Ericsson GS18. See my other message. You may also consider the Siemen's M1 which is purely a GSM modem (no voice) and costs more (a little) than the GS18. The GS18 has pager (various), voice, SMS, and a fax capability built in. These can be accessed via the RS232 communications port (I say all, but I haven't actually used every one of these via serial communications!)
