My phone is displaying the wrong number when texting/calling. What should I do?

Your phone’s settings sometimes keep showing the old or temporary number after a switch. The number people actually see when you call comes from the network, so check that first by calling a friend.

To fix what the phone displays:

• iPhone: go to Settings → Phone → My Number, clear it, save, toggle Airplane mode, then restart. Also check Messages → Send & Receive.
• Android: look for My number under Settings → About phone or under your SIM’s settings, and correct it there. Update your own contact card too.

Resetting network settings is a last resort. You’ll need to re-enter Wi-Fi passwords and set the APN to gamma again.
