Port in 2 lines from T-Mobile, then move the new devices with promo to existing 2 lines

So I have two lines now, with paid off phones on them. I want to port in 2 lines from T-Mobile, and get a device promo on both. When they arrive and I go through activation, can I simply swap the new numbers to an existing unlocked phone, place the new devices on my existing lines, and keep all promotional credits I got when I ported in?

See this thread to see exactly what I mean: https://forums.xfinity.com/conversations/devices/switching-number-associated-with-a-phone-purchased-on-a-promotion/66f6d719a6879c6c7ca90f0f

I just want to make sure this will still work. Thanks everyone.

Hello, @RMG1187 in the Get an iPhone on us with trade-in the disclaimer says: 

 

Trade-in must be completed within 21 days of phone shipment date. Must maintain line required for offer until trade-in is completed. Porting of number is not required with trade-in. Up to $830 via trade-in credit applied monthly to your account over Device Agreement period so long as Device Agreement is in effect. Actual trade-in amount varies depending on model of phones for trade in and purchase and will not exceed the retail value of purchased phone. If line is canceled, voluntarily or involuntarily, or phone payments are accelerated, balance of credits associated with Device Agreement are forfeited.

 

 

Swapping your SIM card will not void any promotions associated with your Xfinity Mobile service. However, it's important to note that if you transfer your old device to someone else, the Xfinity Mobile Care (XMC) coverage cannot be transferred to a different line, even on the same account. Additionally, if you move your physical SIM (pSIM) to another device that is ineligible for use on the network, your service may be temporarily suspended, but this does not affect promotions directly.
