I need help in figuring out which legacy Dell Sierra Wireless DW5811e EM7455 EM7455 (DW5811e) LTE 4G WWAN Module Card is best for LTE-A that covers the US and Mexico, specifically TM, VZ, AT&T and Telcel.
Which Sierra Wireless M.2 LTE-A card do I need for my Dell Latitude 7490. There’s so many USA versions of the EM7455 /DW5811e modules, but I can’t seem to figure out which one I need that will work. For instance, I’ve found these different cards:
KF1W5 MR7VT K9CNF 2J05X 27F80 KRVRM RHPNG 3P10Y
Such a simple question, but after searching for days…I either don’t understand the differences, or the differences aren’t specific to my question. Geez, just kill me now!
