MoreMins has a feature: Tap to Call Back.
Tap to Call Back is designed for missed calls. It allows your real phone number to be shown for a call receiver if one misses your call.
Tap to Call Back works when both sides – a caller and a call receiver - use MoreMins app.
So remind your loved ones to download MoreMins app if they want to see your real phone number in their missed calls list.
