Absolutely. Just pop it out of the older device and into the new one. Easy peasy.
Well obviously I'd have them do it in apple store. I don't have tools to do it plus I'd rather a professional do it. Would I still have any luck selling my iphone 6 without a sim card? Is there more value to phones with cards then without?
Will phone still do anything with no sim card, because I absolutely want to be sure that everything I want to transfer over to new phone is able to go.
I could always just buy a phone with a t mobile sim card in it already and just have them port the number over?
