If anyone is considering T-Mobile Home 5G Internet, you can dramatically improve your connection speeds by getting the devices to connect on the 5G n41 band, where T-Mobile has much more spectrum. Unfortunately n41 is 2500 MHz, which means it's readily absorbed by building materials. Hooking up external antennas to the hotspot requires a bit of playing with the device [1], but can be a big help.
