Which frequency bands does US Mobile use?

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. Depending on the coverage, your device may receive either 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.

For our Warp 5G network, the requirements are a bit different, so we have a handy compatibility checker built into the β€˜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.
