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.

Yes. Enable “Call Recording” in the app’s call settings. Your recordings will appear in your logs after the call ends.

This occurs if your internet connection drops mid-send. Wait a few moments and resend the message once reconnected.

That number was likely purchased by another user moments earlier. Refresh the list to load available options and select a new one.

The destination network might block VoIP connections. Try calling another line or contact the recipient via a different method.
