124 Troubleshooting
Troubleshooting
Here are some problems that you might have while using your phone.
Some problems require that you call your service provider, but most
of the problems you encounter you can easily correct yourself.
Insert Card
There is no SIM card in the phone or you may have inserted it
incorrectly. Insert a SIM card. See “SIM Card” on page 7.
Insert Correct SIM Card
The phone may have been locked by the network operator to work
only with a certain SIM card. Insert the correct SIM card.
SOS Calls Only
You are within range of a network but you are not allowed to use it.
However, in an emergency, some operators allow you to make an
emergency call. See “Making Emergency Calls” on page 13.
No Network
There is no network within range or the received signal is too weak.
You have to move to get a signal that is strong enough.
Wrong PIN, Wrong PIN2
You have entered your PIN or PIN2 incorrectly.
Enter the correct PIN or PIN2, and press
Y E S .
See “Locking the SIM Card” on page 106.
Codes Do not Match
When you want to change a security code (for example your PIN)
you have to confirm the new code by entering it again. The two codes
that you have entered do not match. See “Locking the SIM Card” on
page 106.

You have entered your PIN or PIN2 incorrectly three times in a row.
To unblock, see “Locking the SIM Card” on page 106.
