Data settings for non-AT&T iOS device

Learn how to program your iOS device with the correct AT&T APN and MMS data connection settings to use 4G (HSPA+)/4G LTE data services.


Verify SIM & data plan compatibility

Verify the device has a compatible SIM card and data plan before changing the data settings. This may resolve data connection issues without requiring any changes to your data settings:
  1. To verify SIM card compatibility:
    • You should already have the correct type SIM card if you recently purchased it new from AT&T or an authorized retailer. 
    • If you are using a SIM card from some other source or if you moved an active SIM card to a new device, verify SIM compatibility with 4G (HSPA+)/4G LTE data.
  2. To verify data plan compatibility:
    • If you moved an active SIM card to a new device and did not notify us of that change, your existing data plan might not be compatible. 
    • To update the device information on the account and make any required rate plan changes, the account holder or authorized user can contact us.
