Made the switch from Verizon to T-Mobile two weeks ago. First they paid off the two phones with the keep and switch promotion and now using them for trade-ins on new phones. Ordered iPhone 16 Pro Max Black Titanium 256 GB last Sunday and it will be out for delivery tomorrow!
I work for T-Mobile corporate and we were always told if you did keep and switch you don’t qualify for device promotions until 90 days has passed.
