provider. Check restrictions.
– Number is too long. Check number.
– Make sure no obstruction is blocking the satellite signal. Make
sure that your mobile phone has a clear view of the sky. If you
are inside a building, tunnel, or other structure that limits your
view of the sky, the satellite signal may be weak or unavailable.
– Check that the mobile phone is set to ring.
– If you are near another satellite mobile phone not designed for
the Thuraya system, switch the other satellite mobile phone off
or move as far away as possible to avoid interference. In some
situations, the distance required to prevent interference may be
up to 200 metres. If you see the direction in which the other sat-
ellite mobile phone is transmitting, move out of the communica-
tion path. On ships, move as far away as possible from the ship's
satellite antenna.
– Check that the antenna is properly positioned. The satellite mo-
bile phone requires the antenna to be fully extended.
– Make sure that your mobile phone has a clear view of the sky. If
you are inside a building, tunnel, or other structure that limits
your view of the sky, the satellite signal may be weak or unavail-
able.
– When someone calls you at your mobile phone number, there
may be a delay of up to 60 seconds while the system locates your
mobile phone.
– Weak signal. Move higher, to a window or open space.
– Outside GSM/SAT coverage area. Check service provider's net-
work coverage.
– SIM card not valid. Call your service provider.
– New network not authorized. Try selecting manually, or try other
network.
– Weak signal. Reconnection or connection to another service pro-
vider is automatic. Switching off and on may accelerate this.
