Choose one of the apps and follow the instructions given for installation. This is a very important step, so make sure that you do it correctly; otherwise, you’ll have to start all over again. Run the app for about 30 seconds, like the instructions say.

Now it’s time to put a SIM card in the iPhone and see if it works. If your iPhone recognizes the new SIM card and you have signal, this means that you have successfully unlocked your iPhone. You can now use any SIM card you want from any carrier.
