I've also tested it with a Netzing NE110, and it is not able to send outgoing
SMS messages.

As discussed earlier, this phone really seems like it has a protocol bug.  It
sends a CM SERVICE REQUEST, we answer by CM SERVICE ACCEPT, and the phone never
sends any follo-up message (such as establishing the SAPI3 connection or
actually sending the SMS).

I suppose nobody has tested this phone (or the underlying stack) with
a GSM network that doesn't do authentication and/or encryption.
