/diy/ - Do It Yourself

I'm building an IoT device (which needs a cell data connection) and the A7670x series (C, E, and SA) look good from a price standpoint but the C & E are listed as intended for Europe, Middle East, Africa, etc. I'm in North America. I already checked a bunch of cell carriers (including mine) and they all support LTE on at least one band that the A7670x chips do. I even have a A7670E running right now getting ~300kb/s on my local network. I know LTE can go much faster but that's fast enough for my application. Am I doing something really stupid if I go ahead and use one of these chips (probably the E but could end up being the C or SA) instead of something specifically marketed for North America?
