Maybe this is not exactly the solution you're looking for, but have you considered using a 4G gateway? In the past I've had great success with Sierra Wireles AirLink family. It's pretty easy to send SMS commands through IP with them, so a local Ethernet connection to the gateway should do the trick. Neat devices!
