At T-Mobile, you can get a free iPhone 11 Pro if you meet all of the carrier’s qualifications. First off, you have to switch from another carrier and trade in your old device, or if you’re an existing customer, you can get one by adding a line to your plan. For either one, you’ll pay for the phone up front, then T-Mobile will pay you back in billing credits each month over a 24-month period.
It’s worth noting that Apple is likely a month out from announcing the rumored iPhone 12, and with any new iPhone release, there are usually a bunch of carrier incentives. Still, it’s a free iPhone now, if you want it and meet the criteria.
