Troubleshooting
If you have trouble with your device, try these procedures before you contact a
service professional.
When you turn on your device, the following messages may appear:
Message
The SIM card is
missing.
Enter PIN.
SIM card blocked.
Your device does not show a signal (no bars next to the network icon)
Try this to solve the problem:
Ensure that the SIM or USIM card is installed correctly.
When using the device for the first time or when the PIN
requirement feature is enabled, you must enter the PIN
supplied with the SIM or USIM card. To disable the PIN
requirement feature, tap Start or the Menu key and on the
My Menu screen, tap Settings > Basic Settings tab >
Security > SIM PIN, and then tap
when phone is used.
Your SIM or USIM card is blocked, usually as a result of
entering your PIN incorrectly several times. You must enter
the PUK supplied by your service provider.
