I've been using a product from Siemens, the TC35/T(http://www.siemens-mobile.de/btob/CDA/presentation/ap_btob_cda_presentation_frontdoor/0,,53_0_0_105_0_0_0,FF.html) which is a stripped cellular with only the modem left. It acts as a regular modem which connects with a serial interface but the difference is that its gsmbased.
I'm interested if nokia have something similar which includes the HSCSD feature which would give me a better connection than the 9600bps given by the TC35.
I've seen the cardphone, but since I wont connect it to a computer I need the serial interface.
Is something like that available?
