11.1.4 Tethering & portable hotspot
This function allows you to share your phone's mobile data connection via USB
or as a portable Wi-Fi access point (Please refer to “6.5 Sharing your phone's
mobile data connection”).
11.1.5 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 “6.6 Connecting to virtual
private networks”.

11.2 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 Dialling Numbers
Fixed Dialling 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.
