If you don’t have a sim card to activate your iPhone then it will be stuck on the activation screen. iTunes will not let you use your iPhone until its activated so you will need to perform a process called “hacktivation.” Hacktivation, as its name implies, is spoofing your iPhone into thinking its activated. This doesn’t mean you will get free cellular service. Rather, it will just trick iTunes into thinking that there is a sim card in your iPhone and allow it to bypass the setup screen. Follow the steps in this video to get your iPhone up and running in no time. The video is performed step by step so you do not get lost during the process.
