Which frequency bands does US Mobile use?

GSM LTE Bands:

GSM LTE offers the broadest compatibility. If your device has Band 2 1900 Mhz for 2G and 3G, you should be able to use it for talk, text, and data. Your device may receive fast HSPA (H+) or slow Edge (E) data speeds. If the device also possesses Band 4 1700/2100 Mhz for LTE, or Band 12 700/740 Mhz for LTE then in most areas you should be able to enjoy high-speed LTE data as well.

Warp 5G Bands:

For our Warp 5G network, the requirements are a bit different, so we have a handy compatibility checker built into the ‘Networks’ page. Just enter the 15 digit IMEI of your device to know if you can use it on Warp 5G.  Most devices that support HD voice / VoLTEBand 4 and 13 for LTE are compatible with our Warp 5G service. We highly recommend that you contact us with your device's make and model + IMEI so our experts can determine which network fits it best. You can usually find the IMEI printed on a sticker underneath the device or on the packaging.
