Default GSM localization - triangulation

The flippant answer is to buy a GSM modem like the Sierra Wireless 312U
(no longer available new). It has an onboard GPS receiver which can be
activated, and the exact position of the modem read with a few AT
commands.

But persevering with your SIM900, the big question is what you can get
out of engineering mode.

I'd try:

AT+CENG=3

followed by:

AT+CENG?

Without a SIM900 myself, I'm not in a position to explore further. I'm
sure you'll have further questions as you progress.
