Related QNAs

The call volume is too low.

Increase your in-call and system volume levels. If still low, plug in earphones for clearer output.

Can I attach media files or images to SMS?

Not yet — CallMama currently supports text-only messages. MMS functionality will be available in future updates.

I changed SIM cards and lost my SMS.

Your messages are tied to your CallMama account, not your SIM. Log back in using your same credentials to recover them.

Why are my messages being sent twice?

Avoid tapping the “Send” button multiple times if your network is slow. The system automatically retries if the first attempt delays.
