Switching to a new wireless carrier used to mean wasting part of your day waiting in line at a carrier store. Luckily, those days are over, and T-Mobile has made it easy for customers who are ready to join its network to make the switch right now.

All you have to do is plug your device's information into T-Mobile's IMEI check. If your phone is eligible, you can switch to T-Mobile in less than 15 minutes online or with the T-Life app. If you bring your own device, you may also qualify for up to $800 in rebates for T-Mobile to help you pay off your phone at your current carrier.

Here's how to use the T-Mobile IMEI checker to switch.

What is T-Mobile's IMEI checker?


T-Mobile's IMEI checker is an online tool that checks your smartphone's compatibility with T-Mobile's network. You'll instantly discover if your device will work with T-Mobile, without you having to visit a store.

What's an IMEI?

Your phone's IMEI (International Mobile Equipment Identity) is a unique 15-digit number that identifies your specific phone. It tells carriers which model of device you're using and which networks it's compatible with, and allows carriers and authorities to track your phone or blacklist it if it's stolen.

How to bring your own device to T-Mobile using the IMEI check


Using T-Mobile's IMEI checker is fast and easy. Plus, if you have a newer smartphone, there's a good chance that it's compatible with T-Mobile's network and you can instantly switch to T-Mobile using an eSIM.

To use T-Mobile's IMEI checker and switch:

  1. Go to T-Mobile's online IMEI checker.
  2. Go into your device settings and find your IMEI number.
  3. Plug the IMEI number into the checker.
  4. If it's compatible, make a new T-Mobile account.
  5. Make sure your device is paid off and unlocked from your current carrier.
  6. Select a new T-Mobile plan and activate it using your current phone number.

If you're bringing over your current phone to T-Mobile, you may qualify for help paying off your device. T-Mobile is offering up to $800 to help customers from select carriers—including AT&T and Verizon—pay off their outstanding device balances so they can switch. Even better, this deal also applies to family plans, so you can use it to help pay off up to four lines.

T-Mobile's best wireless plans


If your phone is compatible with T-Mobile, you'll need to pick the right plan before you switch. T-Mobile has plenty of options to meet different needs and budgets.

The Essentials Saver plan is a budget option that includes unlimited talk and text and 50GB of premium data for just $50/month. For a family plan with four lines, you can get Essentials Saver for just $100/month ($25/line).
