APN & Cellphone Setup

T-Mobile / Verizon / AT&T Postpaid APN settings for iPhone & Android

If you switched to T-Mobile / Verizon / AT&T Postpaid and data, picture messages (MMS) or hotspot stopped working, your phone is probably still using your old carrier's APN. Enter the T-Mobile / Verizon / AT&T Postpaid settings below exactly as shown, save, restart — then test with Wi-Fi off.

📱 iPhone: Settings → Cellular → Cellular Data Network🤖 Android: Settings → Network → Mobile Network → APN → + New🔄 Always restart after saving

T-Mobile / Verizon / AT&T Postpaid

Postpaid APNs auto-configure via carrier settings update, so there is no single combined value to copy — use the row for your carrier only if you must enter one manually (for example on an unlocked international phone). On a normal postpaid line, accept the carrier settings update instead of typing values.

Troubleshooting T-Mobile / Verizon / AT&T Postpaid

Postpaid-specific check: on a postpaid line, a hand-typed APN is usually the problem, not the fix. If data broke after you edited settings, delete the manual APN entirely, install the carrier settings update your phone offers, and restart — T-Mobile, Verizon and AT&T postpaid all push correct values automatically, and a manual entry overrides them until it is removed.
