Why can’t I send SMS from my CallMama number?

Ensure your account has SMS credits and a good internet connection.

Use international format (+countrycode) when sending.
Restart your app if the message queue freezes.

Related QNAs

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.

I can’t find my purchased number.

Go to My Numbers → Active Numbers and refresh the page. Logging out and back in forces a full sync from our server if it doesn’t appear right away.

My number isn’t activating after payment.

Activation usually completes within minutes, but delays can occur.

Restart the app or log out and back in.
Ensure your payment was successfully processed.
If still inactive after 10 minutes, contact support@callmama.com with your transaction ID.

International calling option disappeared.

This can occur after an app update. Restart or reinstall the app — it will re-sync all features.
