The ZTE 5G Mobile WiFi Router MU5001 supports various 5G and 4G frequencies, but it is important to check if they are compatible with the networks available in the USA.

- 5G frequencies: The device supports sub6G frequencies such as n1, n3, n5, n7, n8, n20, n28, n66, n71 and mmWave frequencies such as n257, n258, n260, n261. However, in the USA, specific frequencies are used by the different suppliers, such as n71, n260 and n261, some of which might match.
- 4G LTE frequencies: It supports LTE FDD and TDD frequencies, including B1, B3, B5, B7, B8, B20, B28, B38, B40, B42 and B43. These frequencies are widely used in the USA and should be compatible with most suppliers.

However, it is advisable to check with the local network provider in the USA before purchasing to ensure that the device supports all the required frequencies to ensure optimum performance.
