Operation Manual

Troubleshooting 87
After 5 or 10 failed attempts (depending on the type of SIM
card), the SIM card is permanently locked. You must then
contact your network provider to obtain a new card.
SIM LOCKED
In certain cases, the handset can only be used with some
types of SIM cards. This message means that the SIM card
you are using does not match the phone. Take the SIM card
out, and switch the phone on again. If the message
SIM not
present appears on the screen, you will need to check its
compatibility with the phone vendor. If not, please contact your
after-sales service.
No call connection
Check that the number you have dialled is correct.
If the icon is displayed without any network name displayed,
only emergency services can be called.
Check the status of your credit.
Check that the SIM Card you are using offers the service you
are requesting; check if its validity has not expired.
Check and deactivate the outgoing calls restriction when
necessary.
The network could be saturated. Try later.
If the problem persists, please contact your Technical
Helpdesk.
No incoming calls received
Try to make a call in order to check that the phone and the
network are operational.
Check and deactivate the permanent call forwarding
(permanent call forwarding icon displayed on the screen).
Check and deactivate the incoming calls restriction when
necessary.
If the problem persists, please contact your Technical
Helpdesk.
Poor reception quality when calling
Avoid placing your fingers on the bottom of the phone, where
the aerial is integrated: the phone will have to use full strength
to establish a quality transmission.
