My ipad mini is about to die. I love the mini. I travel a lot and it is my go to device for when I am on the road. I am grandfathered in on the ATT unlimited data plan. Since it doesn’t look like Apple is going to update the ipad mini, i was thinking of buying the iphone Xs Max in full without a contract and using it as my ipad mini replacement. Is it possible to use my unlimited ATT ipad data plan on an iphone Xs Max? Without activating it as a phone? Just have the unlimited data plan from my iPad? That would be pretty cool if possible. Thanks for any replies.
