How to Change GSM Settings on an iPhone
- 1). Turn your iPhone on and allow it to boot up.
- 2). Enter the Settings menu. It has an icon that looks like gears.
- 3). Select carrier and choose the carrier or network you would like to use. If your iPhone does not have this option, enter the "General" menu. Again, it has a setting that looks like gears.
- 4). Select the option labeled "Network." It is a few down from the top, but has no icon. Select the network you wish to use, and your iPhone will start to communicate over that network.
- 5). While you are in the menu turn off Data Roaming to prevent racking up charges as your iPhone does simple things like checking for email.
