This scenario is trivial, as far as the Sierra Wireless Airlink supports UDP client/server links. I.e., a properly configurated gateway (easily done through their web interface) should be able to accept UDP packets on any defined port and accept messages in the form '<<<phonenumber,format,length,message>>>', so just using netcat to send the line
<<<16046556677,ASCII,14,5448495320495320412054455354>>> (being the message formatted in hex ASCII, in this case 'THIS IS A TEST') will do the trick. You should receive another UDP packet to a port of your choice ACKing the message. And that's all.
