5. Connect your iPhone to your PC and open iTunes.
6. Click Shift on your keyboard and at the same time click Check for Update in the iTunes window.
7. On the right-hand side there should be a drop-down, click on it and select “iPhone Carrier Configuration files (*.ipcc)“, find the ATT_US.ipcc file and then click Open.
8. Reboot your iPhone. MMS should now be working!
