Yes, sim900 supports AT+CGDATA command, but unfortunately I can't make it
work. I get no error messages, but the connection is not being established.
I wrote about this issue to SIMCOM, but with my local distributor this is
long story.

If I get answer from SIMCOM about AT+CGDATA and make it work properly, I
promise that never send again patch with this funny mistake;)

Anyway, Denis wrote some time ago, we can implement quirks for separating
various models of modem modules of one manufacturer. Like this:

OFONO_VENDOR_SIMCOM_SIM900
OFONO_VENDOR_SIMCOM_SIM5216E
