11.1.4 VPN settings A mobile virtual private network (mobile VPN or mVPN) provides mobile devices with access to network resources and software applications on their home network, when they connect via other wireless or wired networks. Mobile VPNs are used in environments where workers need to keep application sessions open at all times, throughout the working day, as the user connects via various wireless networks, encounters gaps in coverage, or suspend-and-resumes their devices to preserve battery life.A conventional VPN cannot survive such events because the network tunnel is disrupted, causing applications to disconnect, time out, fail, or even the computing device itself to crash. For more information of VPN, please refer to section 6.5 Connecting to virtual private networks. 11.1.5 Mobile networks Data roaming If you don't need to transmit data on other carriers' mobile networks, unmark the check box of Data roaming to avoid incurring significant roaming charges.

A mobile virtual private network (mobile VPN or mVPN) provides mobile
devices with access to network resources and software applications on
their home network, when they connect via other wireless or wired

keep application sessions open at all times, throughout the working day,
as the user connects via various wireless networks, encounters gaps in
coverage, or suspend-and-resumes their devices to preserve battery life. A
conventional VPN cannot survive such events because the network tunnel
is disrupted, causing applications to disconnect, time out, fail, or even the
