Solving Problems
Before contacting the after-sales service, perform the
following simple checks. They may save you the time and
expense of an unnecessary service call.
When you switch your phone on, the following
messages may appear
Insert SIM Card
Check that the SIM card is correctly installed.
Phone Locked Enter Password
The automatic locking function has been enabled. You must
enter the phone’s password before you can use the phone.
Enter PIN
You are using your phone for the first time. You must enter the
Personal Identification Number supplied with the SIM card.
The option requiring that the PIN be entered each time the
phone is switched on was enabled. You must enter your PIN and
then disable this option if so required.
Enter PUK
The PIN code was entered incorrectly three times in succession
and the phone is now blocked. Enter the PUK supplied by your
network operator.
“No service,” “Network failure” or “Not done” is
displayed
The network connection was lost. You may be in a weak signal
area (in a tunnel or surrounded by buildings). Move and try
again.
You are trying to access an option for which you have not taken
out a subscription with your service provider. Contact the
service provider for further details.
