Hello,
This is my first time of working on GSM.
I have got a kit of SIM900A interfaced with ARM7.
To begin with, I am facing following problems...
1. I cant insert the sim card in the slot.
When I try to lock, the sim card oozes out of the slot.
2. I can just see the power on LED on of the SIM900 module at power on. The other LEDs like netlight and status are off completely.
3. I dont have the datasheet of the SIM900A module. Even I tried a lot on google, I could not find it.
(So, I dont know the exact initiation sequence at power on for the SIM900A)
Kindly help me resolving my problems.
