Cellular terminals or mobiles operating over radio signals and cellular network
cannot be guaranteed to connect in all possible conditions (for example, with
unpaid bills or with an invalid (U) SIM card). When emergent help is needed
in such conditions, please remember using emergency call. In order to make or
receive a call, the cellular terminal or mobile must be switched on in a service
area with adequate cellular signal strength.
The cellular terminal or mobile contains a transmitter and receiver. When it is
ON, it receives and transmits radio frequency signals. RF interference can
occur if it is used close to TV set, radio, computer or other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to
turn off wireless devices such as your phone or other cellular terminals. Areas
with potentially explosive atmospheres include fueling areas, below decks on
boats, fuel or chemical transfer or storage facilities, areas where the air
contains chemicals or particles such as grain, dust or metal powders, etc.
