Mor,
I am not familiar with any of the GSM modems, but it does seem that getting one that will allow you to connect to a Serial port and communicate using RS-232 would be the way to go. You will have to know the command set that the modem would use to communicate to be able to send and receive SMS message, but once you know this you could use the VISA commands to communicate with the serial port and to the modem. So if you are looking for some general steps to follow...
This is just a general outline of what you could do to get something like the application you described working. I hope this helps!

Hello
Sorry I am so late . I just saw the thread today.
I worked with Wavecom gsm modem ( oldet than the one you refer and no in Labview) and they are really good and robust.
They use standard modem drivers and standard AT commands ( and some special )
But you can use most GSM/GPRS telephones. I know siemens and nokia have drivers and cabling for sending sms data fax, etc.
Just a point: wavecom modem supply in fron AC. Mos tels can not have data cable and AC supply at the same time, so if you plan to live it unnatended, make sure all data an Power supply cables can be plugged at the same time.
Hope it helps.

Hello
Sorry for my explanatio. When I said "standard AT coomands .." I meant commands in format "AT...".The character 3 and next can be different in some modems. This is true even in AT commands for smartlink modems and conceptronic modems.
Besides that, there are some kind of standards in AT commands for gsm telephones.
At least, documentation refers to publications that are suposed to be kind of standards. ( see references in attached zip)
Attached zip is made up of 3 documents: AT commands for some Siemens mobiles, AT commands for a wavecom modem and an ETSI document about AT commands for GSM telephones. Thera are more ETSI documents about this commands.
You will see that some SMS commands for Siemens and Wavecom are the ones recommended by ETSI.
Hope this helps you to send SMS whit your siemens.
Cheers
