Something supporting USB Communications Device Class: Mobile Broadband Interface Model (umb driver) would be best. umsm is old crap. Given the different band use in different countries, I think a soldered module would be unwise unless the device is targetted at a particular market. You're looking at what, 3 or 4 variants presently? My vote would be for a mPCIe NGFF slot and a SIM carrier on the board hooked up to it.
