Recovering connection after losing network coverage and getting it back

Hi Ravi,
I’m using sim800.During vehicle movement if network coverage is lost, the tcp/ip fails, but once the vehicle enters network available zone will the TCP/IP automatically recover or do i need to execute some commands like register network in order to get it working.What is the best way to go about it?

Network will auto reconnect, But TCP connection will be lost and you have to reinitiate the TCP connection process.
