APN & Cellphone Setup

Tello (T-Mobile) APN settings for iPhone & Android

If you switched to Tello and data, picture messages (MMS) or hotspot stopped working, your phone is probably still using your old carrier's APN. Enter the Tello settings below exactly as shown, save, restart — then test with Wi-Fi off.

Tello (T-Mobile)

Most phones load Tello's settings automatically. Enter these only if data, hotspot or picture messages fail. Values from Tello's Help Center.

  1. Delete any old APNs from your previous carrier (keep only this one selected).
  2. Save → select the new APN → toggle Airplane Mode for 10 seconds.
  3. Test: turn Wi-Fi OFF, load a page, send a picture message, test hotspot.

Troubleshooting Tello

Tello-specific check: on Android, first reset APNs to default and confirm Tello (or fast.t-mobile.com) is selected — add the wholesale APN only if that fails. On iPhone, use wholesale for Cellular Data and Personal Hotspot and service for MMS. Test picture messages with Wi-Fi off; MMS generally does not go over Wi-Fi.
