Hello....
I am recently purchased SIM800 and It is replaced with SIM900A and changed according to SIM800.
I already refereed datasheets of SIM800 and SIM900A. Both are identical, but slightly changed of pins in SIM800 which are non functional for SIM900A.
Also Voltage Range is different as SIM900A: 3.2V to 4.8V & SIM800: 3.4V to 4.4V. So i changed in supply as i was giving 4.4V to SIM900A and now i am giving 4.1V to SIM800.
SIM900A was working fine with all SIm card and also SIM800 is working fine with AIRTEL & TATA DOCOMO Sim card, but when i replace it with VODAFONE IN or IDEA Sim card, it reset continuous and can not detect Network.
So i can work with AIRTEL & TATA DOCOMO on SIM800 but i can not work with VODAFONE IN or IDEA on SIM800.
If any one knows solution of this problem then Please guide me to solve this problem.
