Is possible to send sms, only when there is no internet connection on android. I have gone through connectivity manager class thorough where i m able to send sms but each time, whenever 2G voice call started, or after switching on the phone. I wanted to send sms only when device goes to Airplane mode / Or Packet data disabled or Not internet pack .
Thanks....
