Not sure if it's possible but when I try and use PureVPN over my mobile connection I use up my data quota very quickly. It would be nice to find out how much overhead having PureVPN on constantly over a mobile connection?

That way as part of your technical documentation and sales pitch you could add the minimum mobile data quota for a constant connection.

Also is there a way, if necessary, to cut down on the mobile data used, maybe having a VPN connection that isn't needed to be constantly connected using mobile data. Maybe it drops the connection and quickly reconnects when necessary. The connection would be stalled so you don't have to recreate the full connection when you need it.
