Hi all.

I am facing a problem with my device (having SIMCOM SIM900D Module) when it gets into GSM Blind (No Network) Region.

I have some device suing SIM900D. Basically its a GSM-GPS Tracker. When I did test continuous run for 24hr at my home. Everything works fine. But while the device is in Car, then sometimes in road GSM Blind area comes. Then the problem happens.

Problem I am facing is:

My Device always connected with GPRS and busy with sending data to a remote IP with 5 sec interval. But when device falls into a GSM Blind network area then it totally stopped. Something hanging. When GSM Network comes again, device not back to operating state. Still GSM Module not functioning.

Any advise ... what are the check-points to debug and what is the idea to fix this?

Thanks.

Regards.
