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.

Call settings

Use Call settings to configure normal phone call settings and other special
features offered by your carrier. You can also use Call settings to configure
the phone so that it can place outgoing calls only to a fixed set of phone
numbers.
11.2.1 Fixed Dialing Numbers
Fixed Dialing Number (FDN) is a service mode of SIM, where outgoing
calls are restricted to a set of phone numbers. These numbers are added
to the FDN list. The most common practical application of FDN is for
parents to restrict the phone numbers to which their children can dial.
For security reasons, you'll be prompted to enable FDN by entering SIM
PIN2 which is usually acquired from your service provider or SIM maker.
11.2.2 Service Dialing Numbers
Service Dialing Numbers (SDN) is a service mode of SIM, where you can
place the call from the SDN list. These built-in numbers are added to the
SDN list by operator.
