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.
