It would be useful to mention the name of the modem and manufacturer as 
a lot of modems identify themselves as QUALCOMM INCORPORATED, even 
though they are made by other manufacturers.

The modem only supports 2G and 3G, does your carrier still support it as 
in some countries they are turning off 2G/3G and only allow 4G.
