Related QNAs

How do I change my number type from local to toll-free?

Delete the existing number and purchase a new toll-free one. Each number type uses a separate routing category.

Why does the SMS feature use mobile data instead of my SIM?

CallMama SMS works over the internet (VoIP), not via your cellular provider. A stable connection is needed for sending or receiving.

Can I receive OTPs on virtual numbers?

Yes, most online services support CallMama numbers. However, some banks block VoIP-based OTPs for security reasons.

Can I use the same number on multiple devices?

Yes — you can log in with the same credentials on several devices. Just note that active calls work on one device at a time.
