About T-Mobile Switch Deals

T-Mobile is one of the most aggressive carriers when it comes to switch promotions. Their port-in deals regularly include free flagship phones like the Samsung Galaxy S26 Ultra and iPhone 17 Pro Max, often with no trade-in required. These deals are available when you activate a new line and port in a number from a competing carrier family.

To qualify, you need a phone number from outside the T-Mobile family. That means numbers from Verizon, AT&T, or Cricket work. Numbers from Metro by T-Mobile or Boost Mobile won't qualify since they're part of the same carrier family. If your current number is on a T-Mobile family carrier, you can purchase a port number from Verizon or AT&T for $14 and use it to claim the deal.

T-Mobile also stands out with programs that pay off your old carrier's early termination fees and remaining device payments, making it easier to switch without financial penalties. Most deals require activation on a qualifying plan like Go5G Plus or Go5G Next, and device credits are applied as monthly bill credits over 24 months.

T-Mobile uses 24-month bill credits

T-Mobile phone deals typically spread the discount over 24 monthly credits. If you cancel early, you owe the remaining balance, but the total commitment is shorter than Verizon's 36 months.

Unlock timeline: 24 months (postpaid) / 365 days (prepaid)

Fast track: $100 refills + 14 days (prepaid only)

Frequently Asked Questions

What do I need to qualify for T-Mobile switch deals?

You need to port in a phone number from a competing carrier family. T-Mobile, Metro, and Boost are in the same family, so you need a number from Verizon, AT&T, or Cricket. You also need to activate on a qualifying plan — usually Essentials or higher.

Are the free phones really free?

Yes, but the credits are applied monthly over 24-36 months on your bill. You pay the full device cost upfront or on an installment plan, then receive equal bill credits each month. If you cancel before the credits finish, you owe the remaining balance.

Can I keep my current phone number when switching to T-Mobile?

Yes. You can port your personal number to T-Mobile. However, if your number is already on a T-Mobile family carrier (Metro or Boost), it won't qualify for port-in promotions. In that case, buy a $14 port number from a qualifying carrier to claim the deal.

How long does it take to switch to T-Mobile?

The in-store process takes about 30-60 minutes. Your new T-Mobile line activates immediately, and the number transfer completes within a few hours. You can walk out with a new phone the same day.

Does T-Mobile pay off my old carrier contract?

T-Mobile frequently offers programs like "Keep & Switch" that reimburse early termination fees or remaining device payments from your old carrier. You typically need to submit your final bill showing the balance. Check current offers when you visit the store.
