Related QNAs

My messages are delayed for several minutes.

Delays usually occur during carrier congestion.

Wait a few minutes; messages send automatically when the route clears.
You can enable “Delivery Retry” in settings to handle network delays.

The international call button is greyed out.

This happens when your balance is zero or the feature isn’t activated. Add funds and refresh the app to unlock calling options.

My call ends unexpectedly after a minute or two.

Battery optimization or data saver mode can interrupt ongoing VoIP calls. Add CallMama to your phone’s “Unrestricted Apps” list.

I hear a busy tone immediately.

The recipient’s line is busy or network is congested. Wait a few seconds before redialing.

What are your feelings
