Hi to all,
I am facing an issues while sim900a goes to roaming networking.In home network there is no issues if my device run more then month but once it reach into roaming network it goes to network searching always.I reset simcom powerkey in software as well as hardware but it always shows network searching.Once i remove the simcard and put it into mobile and again i put into device it works?Why it behave like this.Can anybody tell me what is this problem?How to solve this?
 

Check with simcom regarding the firmware of the module...This should be a problem with the SIMCOM firmware..Make sure you have the latest firmware..
