⁵T-Mobile in the United States only officially supports LTE Cat NB1, which is not supported by this device. T-Mobile has unofficially enabled LTE Cat M1 in some areas, and where enabled, this device can connect to it. There is no coverage map as T-Mobile does not acknowledge the existence of LTE Cat M1 coverage.

⁶Not recommended due to permanent roaming restrictions. While the device may initially work, it may be blocked by local operators without warning.
