Hai, I am using sim 900 modem as a server. My gprs server is running correctly and clients can connect to it. But after listening for a short time, it becomes unavailable in the network.i.e, no clients can connect to it. But when I checked the status of modem, it says it is still in LISTENING mode. Does anyone faced this problem? Thank you
