SIM card Toolkit (STK) services are
value-added services provided by your
network provider. Your mobile phone
supports STK service, but if your SIM
card and network provider do not
support the service, these functions
can’t be used.
You can add whitelists and blacklists,
and set to enable blacklist, enable
whitelist or off.
You can set caller name and active
time.
You can choose weight and length in
the unit conversion.
The bluetooth device must be paired
before the communication is
performed.
You can turn on or off bluetooth
on your phone. When bluetooth is
on, the icon will appear in the
status bar.
