Wireless Joint

Hi All! I live in an rural area with the closest tower around 5 miles. I'm using AT&T and the surrounding towers have bands 2, 5, 12, and 14; possibly band 30 but i think that tower is too far.
What's the major difference Quectel EM12-G CAT12 M.2 Modem and Sierra Wireless EM7511 CAT-12 LTE-A Pro Modem? Any pros & cons going with either one? Thanks

I haven't used them each but Id check their websites respectively to check what bands they cover, on the data sheets. From what I've read both are very well liked and don't seem to have any issues I've read about
