Actually I bought I phone 17 for my brother so can I put an Apple care+ for him from my phone ? I bought it on 23 Jan 26
yes bro. you can call apple support and they will guide you steps to activate applecare+ for your brothers device. sometime they ask you to come in video call to verify the device physical condition. If they didnt ask then no problem. else you have to visit nearest apple service center to activate applecare+.
