Hi Folks,
Have a prototype working reasonably with SIM300, but have been told that SIM300 is an obsolete product and that I should move to SIM900B. On researching here a bit, I found that people have reported lots of problems with SIM900B, while making the move from SIM300. The problems reported are like -
1) SIM not detected
2) Unable to register to network
3) Module power-down immediately after registration to network
4) Unable to send SMS (although receiving SMS seems to work)
and each of these problems seem to have been reported by multiple people. Wondering if anyone here has cracked it, and has got SIM900B working.
My requirements are -
a) Send / receive SMS
b) Send / receive USSD
c) Establish data connection via GPRS / EDGE
d) Send / receive voice calls
Folks who have it working well, if you have had to apply some tricks / caveats then kindly do share.
Thanks,
Jay
