Is SMS the same as a text message?

Yes, SMS (Short Message Service) is a protocol for sending text messages between mobile phones. While “text message” is a general term that may include SMS, MMS, or app-based messages, all SMS are text messages, but not all text messages are SMS.

What are the disadvantages of SMS Text Messaging?

Some drawbacks of SMS include: it is typically unencrypted and thus less secure; there is a risk of spam or abuse if recipients opt out; and it has limited content capacity (text-only or very short) compared to multimedia or app-based messaging.

What are the different types of text messages?

Common categories include:

SMS (Short Message Service) – text only, supported across all mobile devices.

MMS (Multimedia Messaging Service) – includes images, video, and larger content.

Instant messaging via the internet (e.g., chat apps) and push notifications.

What’s the difference between SMS and app-based messaging (like WhatsApp or iMessage)?

How do contacts opt out of SMS messages on KrispCall?

Recipients can reply with one of the standard single-word keywords (e.g., STOP, QUIT, UNSUBSCRIBE, END) to unsubscribe from further SMS from that number. After that point, further messages to that number will fail. They can opt back in by replying START, YES, or UNSTOP.

How does SMS text messaging work on KrispCall?
