Because of the large-scale rollouts of new low frequency spectrum by T-Mobile and ATT the last few years, it's best to make sure your router/hotspot/phone is fairly up-to-date and can handle the lower frequency bands. With T-Mobile, you want to be certain that your hotspot/router/phone can operate on bands 71 & 12, with ATT you need band 14. Devices without those bands you loose quite a bit of coverage.
Likewise with external antennas. The antenna needs to be designed for 600 & 700mhz bands to be effective in rural areas that depend on those bands.
(Low frequency bands (600-700mhz) handle long distances better & provide better coverage from the same towers.)
