Unlock iPhone
1) Upload anySIM and support files to your iPhone and run it.
(Download anySIM)
2) Sync your phone before you install so you have a working backup. You’ll also need to set up your iPhone to never go to sleep under “General” in the Settings app. It might also be a good idea to plug your iPhone in.
3) You will then be prompted to “Slide to unlock”, your iPhone to use any carrier’s SIM card, that is.
Once you’re finished, your iPhone will be free from AT&T. It’s that easy.>
