13 Best Virtual Phone Number Providers in UK in 2026

UK businesses are moving to virtual phone numbers to reduce costs and stay flexible. With local and toll-free numbers, smart call routing, and AI-powered features, they offer a faster and more efficient alternative to traditional phone systems.

This guide lists the best UK virtual phone number providers to help your business stay connected, wherever your team works.

How we evaluated the best UK virtual phone number services

To bring you this list, we carried out a comprehensive review of the UK’s leading VoIP and virtual phone number providers from the ground up. Rather than relying solely on feature lists or marketing claims, we closely examined verified user feedback and analysed independent review platforms. 

Every provider was scored against five core pillars, each weighted to reflect what matters most to businesses operating in or expanding into the UK market:

• Affordability & value for money (25%) 

We analyzed beyond the base subscription costs. Hidden fees like number porting charges, per-minute billing surprises, and add-on costs for basic features all affected a provider’s score. Providers with transparent, flat-rate pricing ranked significantly higher.

• Ease of use and UK support (20%)

How quickly can you go from sign-up to first call? We prioritized providers with intuitive dashboards and UK-based support teams that understand local regulations and time zone needs.

• AI & advanced UK features (20%)

We tested AI call center capabilities, including call transcription, sentiment analysis, smart routing, and automated summaries, and then scored providers that offer these natively over those that require expensive third-party integrations.

• Call quality and reliability (20%)

We monitored uptime and audio clarity across both mobile data and broadband connections to ensure professional-grade reliability that businesses can genuinely depend on.

• Global reach for UK exports (15%) 

For UK businesses selling internationally, we assessed the availability of international DIDs, ease of adding numbers across multiple countries, and how well each platform supports outbound and blended call center workflows beyond UK borders.

KrispCall is a cloud-based VoIP phone system that enables UK businesses to set up a virtual number in just minutes.  With access to UK local, toll-free, and mobile numbers, companies can establish a professional presence without the cost or complexity of a traditional phone system. 

What sets KrispCall apart as a top virtual phone number provider for UK-based teams is the affordability of its entry-level plans. Even on lower tiers, users benefit from features such as live call monitoring, CRM integrations, voicemail drop, and call notes without upgrading to an enterprise tier. 

The platforms also support inbound and outbound call center workflows and include a unified callbox that consolidates calls, SMS, and contact management into a single, clean interface.

Why we recommend KrispCall?

KrispCall is built for speed and clarity, backed by user reviews on G2, Capterra, and Trustpilot. It’s one of the few platforms where we can obtain a verified UK number and have a functional virtual call center dashboard up and running in minutes.

• Supports number porting so you keep your existing business number hassle-free.
• Seamlessly syncs with popular tools, even in lower tiers, to automate your workflow.
• Responsive 24/7 customer support.

Are there any major downsides of KrispCall?

No provider is perfect, and KrispCall is no exception. Some of the major cons of KrispCall are:

• Since it’s voice- and SMS-focused, video calling is not supported.

2. Nextiva

Nextiva is a US-headquartered cloud communication platform with a strong reputation among businesses seeking a reliable, enterprise-grade VoIP solution. Their 2026 suite, powered by the NextOS platform, excels at merging UK geographic numbers with a sophisticated blended call center environment.

Where Nextiva really pulls ahead is in its depth of contact center solutions. During our testing, we found that its call flow builder, team presence indicators, and multi-level auto-attendant made managing call center operations smoother. 

For larger teams, the addition of the XBert AI receptionist offers 24/7 coverage leads even when your office is closed, a feature growing UK sales and support teams will genuinely appreciate.

Why we recommend Nextiva?

After testing Nextiva extensively and reviewing user feedback, here’s why it consistently ranks among the best virtual phone number UK choices:

• Reliable 99.999% uptime guarantee ensures UK businesses never miss an important call.
• Unified platform that covers voice, SMS, video, and team chat under one subscription.
• AI call center features, including sentiment analysis and call transcription is available natively.
• Create professional call flows in minutes with a drag-and-drop builder.

Are there any major downsides of Nextiva?

Nextiva is a strong platform, but there are a few limitations worth knowing before you commit:

• Some advanced contact center features are only available on higher-tier plans.
• The initial setup and configuration can feel overwhelming for non-technical users.
• International calling rates outside the US and Canada can add up quickly.
• Some users report difficulty adjusting to or canceling long-term agreements.

How much do real users rate it?

G2 rating: 4.5/5 (3400+ reviews)

Is Nextiva affordable?

Nextiva is affordable for small and mid-sized teams, but it becomes expensive for larger organizations that need full contact center functionality. Its lower tiers suit everyday business calling, while higher tiers target high-volume support teams.

Nextiva’s Core plan starts at $15 per user per month and covers essential VoIP calling features for small teams. The Engage plan starts at $25 per user per month and includes tools to help teams handle more inbound calls. Organizations that need advanced call center tools can expect pricing of around $75 per user per month for the Power Suite CX tier, which includes supervisor tools and automation features.

3. Dialpad

Dialpad is a cloud-native communication platform built with AI at its core. UK businesses can get local geographic numbers, 0800 freephone numbers, and international DIDs up and running quickly, all managed through one of the cleanest dashboards we encountered during our testing. 

When we tested Dialpad, the standout feature was its proprietary DialpadGPT, a purpose-built AI that transcribes UK accents with surprising accuracy and provides real-time coaching prompts during live calls. This make its an ideal fit for any virtual call center where managers want to maintain high standards without hovering over every agent.

Why we recommend Dialpad?

Here’s why Dialpad earns its spot among the best UK virtual phone number providers:

• Instantly generates bulleted summaries and action items after every call.
• Scales effortlessly from small teams to enterprise-level contact center solutions.
• Analyze sentiment with AI to predict customer satisfaction scores without sending annoying follow-up surveys.

Are there any major downsides of Dialpad?

Dialpad impressed us in several areas, but there are a handful of limitations that are worth flagging before you decide:

• AI features that make Dialpad stand out are largely locked behind higher-tier plans.
• Customer support response times have mixed feedback on major review platforms.
• International SMS capabilities are limited compared to some competing VoIP providers.
• Some users report occasional delay in voicemail delivery during peak usage periods.

How much do real users rate it?

G2 rating: 4.4/5 (4,600+ reviews)

Is Dialpad affordable?

Yes, Dialpad is affordable for small and mid-sized teams, with entry-level pricing that remains accessible while still offering useful AI-powered calling tools. Costs rise as teams move into more advanced call center features.

Dialpad’s Standard plan begins at $15 per user per month and includes core calling, AI transcription, and unlimited calling in the US, UK, and Canada. The Pro plan costs $25 per user per month and adds CRM connections, multiple phone numbers, and more advanced call routing features. 

Large teams can request custom pricing for the Enterprise plan, which includes full contact center capabilities.

4. RingCentral

RingCentral is widely regarded as the gold standard for enterprise-level unified communications businesses looking to consolidate their entire tech stack. During our testing, we found that RingCentral (specifically their RingEX platform) excels at providing a strong UK presence.

What really stood out was how deeply RingCentral has woven AI into the core calling experience. For teams running an inbound call center, the RingSense AI provides real-time coaching and automated post-call summaries that are incredibly accurate with British dialects. 

The platform’s integrations ecosystem is also one of the deepest we encountered, connecting natively with over 500 business tools, including Salesforce, Microsoft Teams, and Google Workspace.

Why we recommend RingCentral?

After extensive hands-on testing and cross-referencing reviews across G2, Trustpilot, and Capterra, here’s why RingCentral remains one of the top picks:

• Reliable 99.999% uptime SLA means UK businesses experience minimal disruption.
• Background noise reduction delivers consistently clear HD audio even in busy environments.
• Advanced multi-level IVR and call routing handle high inbound call volumes with ease.
• Built-in video conferencing, team messaging, and VoIP calling all under one platform.

Are there any major downsides of RingCentral?

RingCentral is a powerhouse platform, but it comes with a few trade-offs that are worth considering before signing up:

• Pricing is among the higher end on this list, which can be a stretch for smaller teams.
• The sheer volume of features can feel overwhelming for businesses with simple needs.
• Some users report that customer support response times are inconsistent during peak periods.
• Certain advanced contact center features require purchasing add-ons at an extra cost.

How much do real users rate it?

G2 rating: 4.3/5 (2,900+ reviews)

Is RingCentral affordable?

RingCentral is not a budget option, but it offers fair value for businesses that need a full-featured VoIP and call center platform. The pricing reflects its depth of features and broad platform coverage.

RingCentral’s Core plan starts at $20 per user per month and includes unlimited domestic calling, IVR, and team messaging. The Advanced plan costs $25 per user per month and adds CRM connections, deeper call controls, and reporting tools. 

Large teams running blended or AI-powered call centers can choose the Ultra plan at $35 per user per month, which includes unlimited storage and advanced reporting tools for high-volume operations.

5. 8×8

8×8 is an enterprise-focused cloud communication platform that brings together voice, video, chat, and contact center capabilities under one unified umbrella. 8×8 excels at providing a unified XCaaS (Experience Communications as a Service) platform that blends the best UK virtual phone number services with contact center solutions.

Where 8×8 genuinely stands out is in the depth of its contact center solutions. During our testing, the platform’s omnichannel routing manages inbound interactions across voice, email, chat, and social from a single queue. Its analytics workspace also offered granular real-time and historical reporting that gives managers running inbound, outbound, and blended call center operations a genuinely clear picture of performance at every level.

Why we recommend 8×8?

Here are a few reasons why we recommend 8×8 as a virtual number provider in the UK:

• Omnichannel routing manages voice, email, chat, and social interactions from one unified queue.
• Analytics workspace delivers detailed real-time and historical reporting for performance-driven teams.
• Highly scalable architecture supports everything from small teams to thousands of concurrent agents.
• Deep integrations with Salesforce, Microsoft Teams, and other enterprise tools work seamlessly.

Are there any major downsides of 8×8?

8×8 is a good platform, but it has some limitations, especially for smaller businesses:

• Custom quote pricing makes it difficult to budget without first going through a sales conversation.
• Platform complexity can be a steep learning curve for smaller or less technical teams.
• Not ideally suited for very small businesses or solo operators with basic calling needs.
• Customer support quality has received inconsistent feedback across major review platforms.

How much do real users rate it?

G2 rating: 4.2/5 (1,200+ reviews)

Is 8×8 affordable?

8×8 operates on a custom pricing model, which means the cost ultimately depends on your team size, required features, and the scale of your contact center operations, making it better suited to mid-sized and enterprise businesses than to startups or sole traders.

Rather than publishing fixed tier prices, 8×8 structures its offering around two primary solutions. The platform covers core business communication needs, including VoIP calling, team messaging, and video conferencing, with pricing available on request. We’d recommend requesting a call with 8×8’s sales team to get an accurate figure for your team.

6. Grasshopper

Grasshopper is a virtual phone system designed specifically for solopreneurs, freelancers, and small business owners. It acts as a professional layer on top of your current mobile service, allowing you to separate your business calls from your personal life with zero friction.

During testing, we found that Grasshopper genuinely excels at keeping things lean and purposeful. It won’t rival the depth of RingCentral’s contact center solutions or Dialpad’s AI call center capabilities, but for small UK businesses that want a clean, reliable virtual number with just enough features to stay professional, Grasshopper is hard to beat.

Why we recommend Grasshopper?

After hands-on testing and analyzing user feedback from sites like Trustpilot UK and Capterra, here’s why Grasshopper holds its own among the best virtual number UK options for smaller operations:

• Extremely quick setup and deployment.
• Grasshopper doesn’t charge per user, making it very cost-effective for small teams.
• Deliver your message content directly to your inbox for quick reference.
• Clean, intuitive mobile app praised consistently for ease of use across review platforms.

Are there any major downsides of Grasshopper?

Grasshopper is a great fit for small teams, but its simplicity does come with trade-offs worth considering:

• No native video conferencing feature is available within the platform.
• Lacks advanced AI call center capabilities found in more modern competing providers.
• Not designed to scale into the territory of blended call centers or full contact centers.
• No CRM integrations available natively, requiring manual workarounds for sales teams.

How much do real users rate it?

G2 rating: 3.9/5 (150+ reviews)

Is Grasshopper affordable?

Yes, Grasshopper is affordable for very small teams and solo founders who want a simple business number without paying per-user fees. Its flat monthly pricing can be cost-effective when multiple people share one main line.

Grasshopper’s True Solo plan starts at $14 per month and includes one phone number with three extensions. The Solo Plus plan costs $25 per month and provides unlimited extensions on a single number. Small teams that need more flexibility can use the Small Business plan at $55 per month, which includes up to four phone numbers and unlimited extensions, keeping costs predictable as teams grow.

7. Phone.com

Phone.com is a straightforward, no-fuss virtual phone number provider with a solid reputation among small businesses and entrepreneurs seeking reliable core calling features without the complexity of enterprise-grade platforms.

What we appreciated most about Phone.com during testing was the ProSI technology, which enabled phone calls to route over the cellular voice network rather than relying solely on data. While Phone.com may not compete with the sophistication of Dialpad or the enterprise depth of RingCentral, for UK businesses that simply need a professional, dependable virtual number solution, Phone.com delivers exactly what it promises.

Why do we recommend Phone.com?

Phone.com is the ultimate utility player for small business communications, and here’s why it earns its place:

• Exceptional flexibility to mix and match different plan types for different users on one account.
• A very clean user interface with a minimalist dashboard.
• High-quality hold music and professional voice recording.
• IP desk phone compatibility gives teams the option of a traditional office phone feel.

Are there any major downsides of Phone.com?

Phone.com is well-suited to smaller operations, but there are some clear limitations that larger or faster-growing businesses should factor in:

• Minute caps on entry-level plans can catch businesses off guard as call volumes grow.
• Lacks the advanced AI call center features found in more modern competing platforms.
• Integration options are more limited than those offered by enterprise-focused providers on this list.
• Native video conferencing is available, but often requires an additional monthly fee to unlock.

How much do real users rate it?

G2 rating: 3.5/5 (30+ reviews)

Is Phone.com affordable?

Yes, Phone.com is affordable for small businesses and budget-conscious teams that want flexible plans without paying enterprise-level rates. Plans start at $15 per user per month, making it one of the lower-cost full-featured VoIP providers.

Phone.com’s Basic plan costs $15 per user per month and includes core calling features, voicemail transcription, and one phone number. The Plus plan costs $22.50 per user per month and includes unlimited minutes, call recording, and video meetings. Teams that need deeper reporting and CRM connections can choose the Pro plan at $33.33 per user per month, which includes call analytics and advanced call handling for inbound-heavy workflows.

8. Ooma

Ooma is a well-established VoIP provider for small and medium-sized businesses seeking a feature-rich communication platform at a price point that doesn’t require a large IT budget. While other platforms lean heavily into complex AI call center analytics, Ooma focuses on the essential experience that ensures small UK shops never miss a local enquiry.

During our testing, we particularly appreciated how Ooma handles the transition for businesses still tied to physical hardware. Their Ooma Telo and Base Station options allow you to keep using traditional analog handsets while enjoying the benefits of a modern VoIP call center. It’s a practical, middle-ground solution that avoids the overwhelming complexity of enterprise software.

Why do we recommend Ooma?

Here’s why Ooma remains a top recommendation for very small businesses:

• Comprehensive feature set available at base tier without needing to upgrade immediately.
• Video conferencing built natively into the platform supports up to 100 participants per call.
• No long-term lock-ins with contract-free monthly plans.
• Works seamlessly across desktops, mobile devices, and IP desk phones for maximum team flexibility.

Are there any major downsides of Ooma?

Ooma performs well across most areas, but there are a few limitations that are worth factoring into your decision, especially if you’re planning to scale:

• Advanced AI call center features are limited compared to AI-native platforms like Dialpad.
• Its proprietary hardwares aren’t really compatible with other providers.
• Contract terms and cancellation policies have received some criticism across user review platforms.
• SMS and messaging features are more limited than those of competing VoIP providers.

How much do real users rate it?

G2 rating: 4.6/5 (130+ reviews)

Is Ooma affordable?

Yes, Ooma is affordable for small businesses that want a full VoIP feature set without paying enterprise-level prices. 

Its Essentials plan starts at $19.95 per user per month, placing it in the mid-range of business phone providers while still covering essentials like a virtual receptionist and call queuing. Higher tiers, like the Pro plan at $24.95 and Pro Plus at $29.95 per user per month, add useful tools such as call recording, voicemail transcription, and hot desking, making Ooma a cost-conscious option for teams that need more than basic calling.

👉Detailed Ooma pricing

9. Quo (formerly OpenPhone)

Quo, formerly known as OpenPhone, is a modern cloud-based phone system that has rebranded with a sharper focus on AI-powered communication. While legacy providers focus on desk phones and complex hardware, Quo is built entirely for the modern, mobile-first UK startup. 

What genuinely impressed us during testing was Quo’s Sona AI agent, a built-in AI layer that handles call tagging, generates post-call summaries, and can autonomously manage certain inbound interactions without human intervention. For small and growing UK teams that don’t have the headcount to staff a traditional inbound call center around the clock, this kind of intelligent automation is a meaningful differentiator. 

Why do we recommend Quo?

Quo is the gold standard for startup communication, and here’s why Quo earns its place among the best virtual phone number providers:

• Shared numbers and group calling make collaborative inbound call handling genuinely seamless.
• Unified inbox consolidates calls and SMS into one streamlined view for maximum team efficiency.
• Easily create your custom workflows or dashboards with clean webhooks & API.
• Clean, minimal, and intuitive interface.

Are there any major downsides of Quo?

Quo is a strong contender for the right type of business, but there are some limitations worth factoring into your decision before committing:

• Video conferencing is not natively supported, requiring separate tools for face-to-face team communication.
• No call barging features to assist agents during high-pressure calls.
• CRM integration options, while growing, remain more limited than those of longer-established competitors.
• The advanced Sona AI features are a significant price jump from the basic tiers.

How much do real users rate it?

G2 rating: 4.7/5 (3200+ reviews)

Is Quo affordable? 

Yes, Quo is affordable for teams that want AI-powered calling tools without paying enterprise-level rates. Its entry pricing stays within reach for small teams, while higher tiers suit growing inbound-heavy operations.

Quo’s Starter plan begins at $15 per user per month and includes core calling, SMS, shared numbers, and basic AI call tagging. The Business plan costs $23 per user per month and adds the Sona AI agent, detailed call summaries, deeper reporting, and CRM connections, making it a strong fit for structured inbound call center workflows.

Larger organizations with complex requirements can go with the Scale plan with advanced AI and priority support at $35 per user per month.

10. Zoom Phone

Zoom Phone has rapidly transitioned from a video add-on to a serious contender for the title of best virtual phone number in the UK in 2026. For businesses already embedded in the Zoom ecosystem, the transition to Zoom Phone feels less like adopting a new tool and more like unlocking a feature that was always there.

During testing, we found that Zoom Phone’s greatest strength is also its most obvious one: seamless integration with Zoom Meetings. Escalating a phone call into a full video meeting with a single click is genuinely useful in practice. Despite its past lite reputation, the current version supports enterprise-grade features such as call monitoring (barge/whisper/takeover) and unlimited auto-attendants, making it a surprisingly powerful virtual call center tool.

Why do we recommend Zoom Phone?

Here’s why Zoom Phone earns its spot among the best virtual phone number providers in the UK for Zoom-native teams:

• Familiar Zoom interface means minimal onboarding time for existing Zoom users.
• Flexible call flip allows active calls to transfer between laptops and mobile devices without any audio interruption.
• Scales well for growing teams already using Zoom for broader business communication.
• Strong call quality backed by Zoom’s established global network infrastructure.

Are there any major downsides of Zoom Phone?

Even a giant like Zoom has its limitations that UK business owners should keep in mind:

• Heavily dependent on the broader Zoom ecosystem, so less compelling if your team doesn’t already use it.
• International calling rates can add up quickly for your team’s calling destinations.
• Detailed reporting often requires an extra power pack add-on.
• Some users report occasional audio sync issues when transitioning between call and video modes.

How much do real users rate it?

G2 rating: 4.6/5 (2,600+ reviews)

Is Zoom Phone affordable?

Yes, Zoom Phone is one of the more affordable options on this list, particularly for teams already paying for a Zoom Meetings subscription, since the two integrate so seamlessly that the combined cost feels well justified.

The plans offered by Zoom Phone begin with the US & Canada Unlimited plan, available to users for as little as $15 per user per month, which covers unlimited domestic calling and core VoIP features. Their Pro Plus plan costs $18.33 per user per month and includes unlimited calling to 40+ countries, including the UK. For businesses that want the complete package, the Business Plus bundle at $22.49 per user per month combines unlimited phone service with the full Zoom Meetings Pro experience and increased cloud storage.

👉 Detailed Zoom Phone pricing

11. AVOXI

AVOXI is a cloud communication platform with a specific focus on global voice infrastructure. While some competitors struggle with international routing, AVOXI’s network is optimized for blended call center environments where clear, low-latency connections to 150+ countries are a non-negotiable requirement. 

What set AVOXI apart during our testing was the reliability of its infrastructure. Multi-factor authentication, automatic failover, and real-time traffic metrics are all AVOXI’s standard features. The platform’s real-time traffic dashboard also gave us a level of visibility into call performance that is useful for managing call center operations across multiple geographies simultaneously.

Why we recommend AVOXI?

Based on our research, here’s why AVOXI earns its place among the best UK virtual number providers for globally minded businesses:

• Automatic failover ensures call continuity even when primary network connections experience disruption.
• Quick number provisioning across global markets is consistently praised on major review platforms.
• Build complex, multi-level phone trees with advanced IVR & auto-attendant.
• Unlimited concurrent calling without additional per-channel fees.

Are there any major downsides of AVOXI?

While AVOXI is a powerhouse for global voice, here are a few areas where it might not be the perfect fit for everyone:

• Domestic-only businesses may find the global focus adds unnecessary complexity to their setup.
• It lacks its own built-in video conferencing suite.
• It does not offer SMS/texting capabilities for UK-based virtual numbers.
• Native CRM integration options are more limited to enterprise-focused providers.

How much do real users rate it?

G2 rating: 4.4/5 (20+ reviews)

Is AVOXI affordable?

AVOXI offers competitive pricing that can be affordable for businesses focused on global calling and that want flexible, usage-based pricing rather than per-user fees.

Plans start with the Launch plan at no monthly minimum for beginners. The Contact plan begins at $29.99 per month and adds call queuing, monitoring, and analytics for growing teams. The Engaged Enterprise plan starts at $49.99 per month, offering advanced routing, VIP calling, and priority support.

12. CallHippo

CallHippo is a virtual phone system designed for sales teams and businesses running high-volume outbound call center operations. It provides a lightweight, browser-first experience that allows an outbound call center to be operational in minutes.

What stood out most during our testing of CallHippo was how well it handles the core mechanisms of outbound calling at scale. Its sticky agent feature ensures that a customer is routed to the same agent they spoke with previously, fostering a sense of continuity and personalized service that is often lost in a traditional virtual call center environment. 

Why we recommend CallHippo?

Based on hands-on testing and reviewing user feedback, here’s why CallHippo earns its place among the best virtual landline UK providers:

• Automate sequential outbound dialing with a power dialer.
• Gain instant feedback on the emotional tone of your calls to improve agent training and customer retention.
• Affordable entry pricing makes it accessible for growing sales teams on a controlled budget.
• Syncs seamlessly with HubSpot, Salesforce, and Zoho to keep your lead data up to date.

Are there any major downsides of CallHippo?

CallHippo is well-suited to outbound-heavy teams, but there are some limitations worth considering before making your final decision:

• Many essential features, like CNAM (Caller ID Name) and spam protection, are sold as separate monthly add-ons.
• Call quality has occasionally been flagged as inconsistent on lower-bandwidth mobile connections.
• Video conferencing is not part of the core platform offering.
• Navigating the different pricing tiers (Bronze, Silver, Platinum) and their various feature gaps is quite confusing.

How much do real users rate it?

G2 rating: 4.5/5 (350+ reviews)

Is CallHippo affordable?

Yes, CallHippo is affordable for small teams, but you must watch out for the add-on trap.

The plans offered by CallHippo begin with the Starter plan, which costs $19 per user per month and covers core calling features and basic call management tools. The professional plan costs $29 per user per month and unlocks the power dialer, smart routing, and deeper CRM integrations. For larger organizations running complex call center workflows, CallHippo’s Ultimate plan is available at $49 per user per month and delivers the platform’s full feature suite.

13. Google Voice

Google Voice is the virtual phone number offering from Google, and it occupies a unique position on this list, not because it’s the most feature-rich option, but because it seamlessly fits into the workflows of businesses already built around Google Workspace. 

What makes Google Voice unique is its intelligent workspace awareness and capability to deliver exactly what it promises. It doesn’t compete with the heavy-duty AI call center features of Dialpad or RingCentral; instead, it offers a clean, distraction-free experience that lives directly in your Gmail and Google Calendar. However, it quickly becomes clear that Google Voice is designed for simplicity rather than scale.  

Why do we recommend Google Voice?

After our hands-on review, here’s why we recommend Google Voice for small teams (under 10) who want a set-it-and-forget-it phone system:

• Native Google Workspace integration makes setup effortless for users of the existing Google ecosystem.
• Superior spam protection with Google’s massive database.
• Unlimited texting within the US makes it useful for businesses with US-facing operations.
•  Delivers message content directly to your inbox for quick reference.

Are there any major downsides of Google Voice?

Google Voice is a capable tool within its intended scope, but its limitations are significant enough that growing businesses should weigh them carefully:

• You cannot use the business version of Google Voice without a paid Google Workspace subscription.
• Limited third-party integrations.
• Advanced contact center features like a power dialer are entirely absent.
• Customer support is notoriously difficult to access.

How much do real users rate it?

G2 rating: 4.1/5 (150+ reviews)

Is Google Voice affordable?

Yes, Google Voice is comfortably the most affordable option on this list, though it’s worth being clear that the low price reflects a deliberately limited feature set rather than exceptional value at scale.

The plans offered by Google Voice begin with the Starter plan, available for as little as $10 per user per month, covering core calling, voicemail transcription, and unlimited US texting for up to 10 users. 

Their Standard plan is priced at $20 per user per month and includes ring groups, call queuing, and desk phone support for growing teams that need slightly more structure. For larger organizations within the Google ecosystem, Google Voice’s Premier plan is available at $30 per user per month, unlocking advanced reporting, automatic call recording, and BigQuery integration for data-driven teams.

What are the different types of UK virtual phone numbers? 

Not all UK virtual numbers work the same way, and choosing the right virtual numbers can make a real difference to how customers perceive your business and how your team manages calls. Here’s a breakdown of the main options you’ll come across:

• Local (geographic) numbers: Local UK numbers carry area codes tied to specific UK regions, such as 020 (London) or 0161 (Manchester). Familiar local caller IDs improve pickup rates, and recipients are 4 times more likely to answer calls with a local area code, which makes outbound call center campaigns significantly more effective.
• National (non-geographic) numbers: UK national numbers start with 03; these numbers work nationwide without being tied to any specific location. They’re a strong choice for businesses that want a credible, professional UK-wide presence without suggesting a regional bias to any particular caller.
• Toll-free numbers: Toll-free UK numbers typically start with 0800 or 0808. These numbers are free for callers to dial, making them particularly effective for inbound call centers, customer support lines, and any business where removing barriers to contact is a priority.
• Mobile numbers: Mobile UK numbers start with 07 and are useful for businesses that rely on SMS workflows, WhatsApp Business communication, or need a number that feels more personal and approachable to their customer base.
