IMPORTANT!
Cellular terminals or mobiles operate using radio signals and cellular
networks. Because of this, connection cannot be guaranteed at all times
under all conditions. Therefore, you should never rely solely upon any
wireless device for essential communications, for example emergency calls.
Remember, in order to make or receive calls, the cellular terminal or mobile
must be switched on and in a service area with adequate cellular signal
strength.
Some networks do not allow for emergency calls if certain network services or
phone features are in use (e.g. lock functions, fixed dialing etc.). You may
need to deactivate those features before you can make an emergency call.
Some networks require that a valid SIM card be properly inserted in the
cellular terminal or mobile.
