I would like to know if I can still sign up for the free Apple TV promotion from my t mobile service
I am wondering if I can still sign up because I have T-Mobile & I wanted to get the free Apple TV subscription for a year ,
iPhone 11, iOS 14
If you got a new iPhone from a mobile phone carrier/service provider, then possibly they act as Apple Authorized Reseller. Apple iPhone and device deals - T-Mobile. Then the offer would apply to you too. It is about getting a new device, not about the cellular plan. Apple TV+ - One Year Offer - Apple
There are some conditions. E.g. you have to redeem the offer within the first three months.
