GSM modem test point with data and SMS support

Probably because MO/MT (mobile originated/mobile terminated) SMS takes place on the cellular "control" channel (somewhat like the "D" channel on a PRI span) and is not seen as "data" by the carrier.

Thanks for your response and three I received off-list.

Multi-tech confirmed that none of their models can do SMS and EDGE at the
same time.  They have to be out of PPP mode to send and receive SMS.

Some additional information on the SAMBA modems can be found at the
manufacturer site:

The SAMBA modems are USB powered and can respond to normal AT commands for
things like signal strength and so forth. Using the sms-tools kit, you can
also send/receive SMS messages. The SAMBA modem I have supports EDGE.

We have some interest in testing the real-world connectivity of several
cellular towers using a GSM modem that has both a IP address on the WWAN and
has SMS support.  Is anyone aware of a self-contained box that supports both
technologies?  EDGE support is preferred, but GPRS would be acceptable.
