Preparing Your Factory Unlocked iPhone for GCI’s Network

October 6, 2016

In order for the iPhone to work consistently on GCI’s network it must be a factory unlocked device. Only Apple’s website or official Apple stores sell factory unlocked devices.

Customers may decide to “jailbreak” or software unlock iPhones from another carrier, however GCI cannot provide network support for these scenarios. We cannot guarantee network functionality.

GCI will attempt to assist with a properly factory unlocked device, and you may call GCI Customer Service for assistance. Unlocked devices are not eligible for GCI mobile device protection.

Syncing your iPhone with iTunes

The iPhone will not connect to GCI’s network until the following steps are completed:

  1. Connect your iPhone to your computer.
  2. Open iTunes.
  3. Select your iPhone and follow the on-screen instructions.
  4. You will have the option to update to GCI’s Carrier Build. GCI recommends you accept this update, but it is not required that you accept the update.

GCI Carrier Update

If you accept the GCI Carrier update you will not need to complete the Setting up your GCI Settings section. Accepting the GCI Carrier update will automatically enter GCI’s data settings and then hide those settings so they cannot be modified.  This update does not lock your phone, it only hides the GCI data settings. If you move to another Carrier, with a different SIM card, you will be able to enter in those data settings.

If you accept the GCI Carrier Settings your About (Menu => Settings => General => About) screen will resemble this screen shot.
