Zadarma is a global cloud telephony platform that offers virtual numbers, VoIP calling, and a full-featured PBX system for businesses and individuals in over 100+ countries. Its pricing appears straightforward, with a free plan and affordable paid tiers ranging from $0 to $79/month, depending on region and features.
However, the platform uses a hybrid pricing structure that combines subscription plans, pay-as-you-go call rates, and add-ons such as virtual numbers and extra storage. This layered pricing model can make it difficult for new users to fully understand the real total cost of ownership, especially when additional charges such as outbound call rates, number rentals, and feature limits come into play.
In this guide, we’ll break down:
- Zadarma’s core pricing plans (Standard, Office, Corporation)
- What features are actually included vs. paid extras
- Common hidden costs and billing nuances
- Whether Zadarma is truly a cost-effective VoIP solution
Overview of Zadarma Pricing and Plans

Zadarma Standard Plan
The Zadarma Standard Plan is the entry-level plan that best suits small teams or startups needing basic PBX features without bundled numbers. This plan usually costs $0 per month per 5 users. This plan includes
- 5 PBX/CRM users
- 200 MB call recording (~14 hours)
- 2 video conference hosts with 20 participants
- Free number porting if you pay 12 months’ prepayment
- Pay-as-you-go for outgoing call minutes
However, it has no virtual or toll-free numbers, and it lacks AI agents or speech-recognition minutes, making it ideal for minimal setups but limiting for growth.
Zadarma Office Plan
One of the recommended plans in Zadarma’s pricing is the Office Plan. This plan is designed for growing teams, starting at just $39 per month per 10 users with an annual payment. It includes:
- 1 virtual phone number
- 400 speech recognition minutes
- 10 PBX and CRM users
- 2GB cloud storage for call recordings (~142 hours)
- 5 video conference hosts with 50 participants
- 100 AI agent minutes
- 10 Concurrent outgoing calls
This plan is considered the best for mid-sized businesses that need AI tools and basic conferencing, though storage may fill up quickly with high-volume recordings.
Zadarma Corporation Plan
The top-tier plan for larger operations is the Corporation plan, designed for large enterprises with more extensive requirements. The price plan is $79 per month for 20 users with a one-year prepaid plan. This includes:
- 20 PBX and CRM users
- 2 Virtual numbers
- Cloud storage limit 4 GB (~283 hours) for call recordings
- Up to 1000 minutes for speech recognition
- 12 Voice menus within IVR (PBX)
- 10 video conference hosts, including 100 participants
- 200 AI agent minutes
Suited for enterprises with heavy AI/video needs, but additional numbers cost $2 each beyond inclusions.
Extra Costs and Hidden Fees in Zadarma Plans
Zadarma plans include pay-per-use elements and add-ons that can increase costs beyond base pricing. These arise mainly from exceeding bundled limits on minutes, numbers, and storage.
- Additional number of users: Charged at $2 per user per month for each additional user, beyond included limits (5 in Standard, 10 in Office, 20 in Corporation); some may incur connection fees or higher rates for special types.
- Calls beyond bundles: Outgoing calls to countries outside the bundle are billed at standard tariffs (e.g., 500 or 1000 mins to 18 countries in paid plans) at ~$0.02/min or higher; no connection fee, but per-second billing applies.
- Concurrent outgoing calls: The number of outgoing calls that can be made simultaneously from your PBX system. To increase the number of outgoing concurrent lines, switch to a different pricing plan or contact support.
- Exceeded cloud storage: Limited to 200MB (~14 hours), 2GB (~142 hours), or 4GB (~283 hours) for recordings; overages require upgrades or deletions, potentially forcing paid expansions.
- AI agent and speech recognition overages: Free minutes capped (e.g., 100 AI mins in Office, 400 recognition); additional usage billed separately, adding variable costs for heavy AI reliance.
What’s Missing in Each Zadarma Plan
Zadarma plans are structured around increasing the number of users, including minutes, and virtual numbers. Here is what is often missing or limited in each Zadarma plan:
Standard plan
The base plan offers unlimited US/Canada calls but lacks bundled resources for growing teams. Not including virtual phone numbers or toll-free numbers means every line costs $2+ per month, limiting scalability without upfront investment. Storage limited to just 200MB restricts recording retention, and zero AI agent minutes hinder modern analytics needs such as speech-to-text.
Office plan
Office ($39 for 10 users) provides 4 numbers and 400 minutes, but caps concurrent calls at 4, which can bottleneck busy teams. Limited to 100 AI minutes and 400 recognition, it falls short for AI-heavy operations that require real-time coaching or QA; teams must pay for overages or upgrade. Video conferencing limited to 5 hosts/50 participants suits small groups but not larger collaborations.
Corporation plan
Even Corporation (for 20 users) restricts concurrent outgoing calls to 20, which may be insufficient for high-volume centers. While offering more free speech recognition minutes (1000) and storage (4GB), it lacks unlimited global calling or advanced AI like live in-call analysis, forcing per-minute extras. No native power dialers or deep CRM automations beyond basics, requiring third-party tools for outbound efficiency.
Zadarma Plan & Pricing Compared To Competitors
KrispCall is a strong competitor to Zadarma in cloud phone services. It offers affordable pricing for each user, making it easier for growing teams to scale.

KrispCall’s pricing starts at $12 to $32 for small teams. It scales to mid-sized operations with advanced call tools and offers custom pricing for Enterprises. Each plan includes one free local number (US, UK, or CA), but there are additional charges for calls and texts beyond the bundled amount.

- KrispCall emphasizes apps (web/mobile) and SMS, while Zadarma focuses on PBX/IVR depth (up to 12 menus) but caps storage/AI.
- Integrations favor KrispCall (100+ claimed) vs. Zadarma’s free CRM/API basics; both lack unlimited international without extras.
- Support is 24/7 for both, but KrispCall highlights dedicated managers for Enterprise; Zadarma has per-plan limits on concurrent calls/storage.
Should you still use Zadarma?
Zadarma offers affordable international virtual numbers and cloud PBX services, making it a good choice for small businesses and remote teams. However, it has slow customer support and potential account issues, posing risks for users needing high reliability. It’s best for budget-conscious users comfortable with a complex setup, while those prioritizing reliable support may want to consider its alternatives.
Pros and cons of Zadarma pricing plans
| ✔️Pros | ❌Cons |
| Offers a free cloud PBX and competitive international rates. | The system is not so user-friendly; non-technical users may struggle with initial setup. |
| Integrates with leading CRMs, including HubSpot, Salesforce, and Zoho, for automated call logging. | Strict compliance requires uploading passports or proof of address, which can cause delays or temporary service suspensions. |
| Provides virtual numbers in 110+ countries for a quick global presence. | Response times can reach 24-48 hours, which is challenging for urgent issues. |
| Delivers high-quality voice calls and stable connections. | SMS reception is typically limited to the country of origin. |
| Includes advanced tools like AI speech analytics and auto-dialers to enhance scales and support workflows. | Some users also report that mobile apps can drain battery life. |
Final Verdict: KrispCall Edges Out on Price
KrispCall delivers superior value at $12–$32 per user/month, compared to Zadarma’s $39–$79 flat rates for fixed-user packs, and includes a free local number from day one, eliminating Zadarma’s $ 2-per-extra-number charges.
Features like unlimited storage on higher plans, 100+ integrations, power dialers, and true unlimited users outpace Zadarma’s capped storage (200MB–4GB), limited AI minutes (0–200), and basic CRM/API.
KrispCall’s intuitive Unified Callbox, bulk SMS, and mobile-first design suit startups/SMBs needing global reach in 100+ countries without Zadarma’s concurrent call limits (4–20) or complex IVR setup.
While Zadarma shines for unlimited US/Canada calls and low international rates, its slow support, compliance hurdles, and per-minute overages inflate the true cost for growing teams, making KrispCall the smarter, more scalable pick.
