Hola,

It sounds like you’re experiencing a frustrating issue with the T-Mobile app on your iPhone 15 Pro. Here are a few steps you can try to resolve the problem:

Close and Reopen the App: Double-click the Home button and swipe up on the T-Mobile app to close it. Then, try reopening it.

Update the App: Check the App Store for any updates for the T-Mobile app and install them.

Uninstall and Reinstall the App: Sometimes, uninstalling and then reinstalling the app can resolve unexpected issues.

Reset Network Settings: Go to Settings > General > Reset > Reset Network Settings on your iPhone.

This will reset Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.

Contact T-Mobile Support: If none of the above steps work, reaching out to T-Mobile’s customer support may provide additional solutions or information on ongoing issues.
