I recently had an issue with my iPhone 7 that needed for my motherboard and battery to be replaced by Apple. Once I got them replaced I tried reinserting my SIM card and now it just works for about 5 minutes then says this “SIM has locked please power cycle and if the problem persists contact Customer Service”
