What is the the different if user enable the "Mobile Data on Demand" ??. Does it means, it will disconnect when there is no data transferring in/out and auto reconnect to Mobile Data when the data transferring ??
Hello, yes it means precisely that. Under the "Mobile Data on Demand" section there is a field called "No data timeout (sec)". There you can specify the amount of time after which the mobile data connection goes down if no data is transferred. This function is only compatible with PPP connection type.
