T-Mobile has been aggressively expanding its network in the last few years. If you’ve turned on a television recently, you’ve probably seen a commercial telling you so. Part of that expansion is T-Mobile’s push into using band 12 (700 MHz) and band 71 (600 MHz). These lower frequency bands can pass through walls and structures easier giving users better indoor coverage.
The process is pretty simple. You either manually enter part of your IMEI number or scan the barcode on your phone’s box. To find your IMEI number, open up the Settings app, then scroll down to about “About phone”, and then press “Status”. You’ll find your IMEI there. You only need the first eight digits of your IMEI for the app to do its thing. Not only will it tell you if your phone can take advantage of Extended Range LTE, but VoLTE, too.
The app is actually designed for T-Mobile’s employees to use, but anyone can download and use it. It’s an extremely useful tool if you’re switching over to T-Mobile from Verizon, AT&T, or Sprint and want to know how your phone will work on T-Mobile’s network. It’s not a guarantee that you’re going to get amazing data speeds, just that your phone will work with T-Mobile’s latest technology.
