APN & Cellphone Setup

Switched and data or MMS isn't working? It's almost always the APN.

After a port, your phone sometimes keeps the old carrier's APN. Pick your new carrier, copy the settings, restart — data, picture messages and hotspot should come back.

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

APN settings by carrier — a full page for each

The quick picker above covers the fix in place. Each carrier also has its own page with the same settings, iPhone & Android steps and troubleshooting — open yours, or bookmark it for switch day.
