The GPRS modules don't normally implement the WAP or MMS stacks, maybe you could implement something like this on the TC45 http://www.tdc.co.uk/gprs/gprs_siemens.htm#tc45java , but I don't know of the software for free.

The externalcommands program at the link above will create a tcp connection using the TC45 modem, you will still set the context using the cgdcont command.

Set up the APN using

at+apn=orangeinternet (example apn)
at+un=web (username)
at+pw=web (password)

then
atd123.123.213.123:1000

will make the IP socket connection
