Do I need a SIM in the phone to update?
My iPhone 6s has no SIM and i don't have one that will work with it. It is currently running IOS 11.0.3 and Im scared to update to IOS 11.2.5 as i don't know if I need a SIM to activate it after updating. After i restored it originally, I needed to borrow a SIM from a friend to use and set up the phone. Thanks.
