106 Troubleshooting
Troubleshooting
This chapter lists some problems that you might encounter while using your
phone. Some problems require that you call your service provider, but most of
the problems you encounter are easy to correct yourself.
Insert Card
There is no SIM card in the phone or you may have inserted it incorrectly.
Insert a SIM card. See The SIM Card on page 5.
Insert Correct Card
The phone is set to only work with certain SIM cards. 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 call the international emergency
number 112. See Making Emergency Calls on page 14.
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
YES.
See The SIM Card Lock on page 58.
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 The SIM Card Lock on page 58.
PIN/PIN2 Blocked
You have entered your PIN or PIN2 incorrectly three times in a row. To
unblock, see The SIM Card Lock on page 58.
