Troubleshooting

5 Cannot make or receive calls

Check to see if you have ‘Flight’ profile turned on. When this profile is active

you cannot make or receive calls.

Make sure that the phone is not off. Close the cover and switch on the phone.

If you get the message INVALID SIM CARD, your SIM card cannot be used in

the communicator. Contact you dealer or system service provider.

Check the status of your call restrictions and forwards, see ‘System services

settings’ on page 105.

The phone may be busy: data or fax is being sent or received, or the communicator

is being used as a fax modem. Wait for the data/fax transmission to end, or

drop the call by pressing the key on the phone keypad.

6 Call quality is poor

Your location may not allow better call quality. This problem may occur especially

in a moving car or train. Move to a location where the radio signal reception

is better. See ‘GSM data transmission’ on page 43.

Reception is usually better above ground level, outdoors and while stationary.

Sometimes even moving the communicator slightly will improve reception.

You can also try using the communicator in the handsfree mode, see page 93.

Remember to turn the antenna to an upright position.

7 Cannot forward or restrict voice, fax or data calls

You may have not subscribed to the service in question, or it is not supported

by the system, or the message center number and the number to which you

want to forward your calls may be missing or incorrect.
