T-Mobile sets its APN automatically on nearly every phone. When it doesn't, usually on an imported or older unlocked phone, data and picture messages fail while calls still work. These are the values from T-Mobile's own support page.
Check these first
- Restart the phone with the SIM or eSIM installed. Most phones request carrier settings again on boot.
- Confirm mobile data is on, airplane mode is off, and the right line is set for data on a dual-SIM phone.
- Make sure activation finished in the carrier's app. A pending activation looks like an APN problem.

Where to enter them
- Android: Settings > Network & internet > SIMs > Access Point Names, then add a new APN. On Samsung: Settings > Connections > Mobile networks > Access Point Names.
- iPhone: Settings > Cellular > Cellular Data Network. This menu only appears when the carrier allows it; most iPhones set the APN automatically.
- Leave any field not listed blank, save, select the new APN, and restart.
If it still won't connect
Reset network settings, restart, and try again. If data still fails, the phone may be locked to another carrier or missing T-Mobile's bands. Check the lock status before spending more time on APN fields.
Mint, Metro and Tello use the same network from $20–$30/mo.
