Please refer to the list below if you encounter any problems when

Your display prompts Enter PIN Code:

Enter the valid PIN code for your SIM card. If you do not know this

code, contact your network service operator immediately.

Your display prompts Enter PUK Code:

If you enter the PIN code incorrectly three times in a row, your SIM

card will be locked. In this case, you have to enter the PUK code to

unlock your SIM card. Please contact your network service operator

immediately.

Your phone prompts Insert SIM card:

Make sure that your SIM card is correctly installed. Check whether

your SIM card works normally. This message may indicate that your

SIM card is defective or damaged. In this case, contact your network

service operator.

Your phone prompts Out of Service Area or Network

Failure:

Check your signal strength indicator. If the indicator shows no signal,

you may be in a basement or a building corner not covered by network.

Move to another location where the signal is strong enough. There is

another possibility: you may be in an area not covered by network. You

may ask your network service operator to inform you of the network

coverage.

The sound is of poor quality, or there is echo or noise,

which makes calling difficult:

Hang up the call, and dial again. Your network service operator may

provide you with a better link when you retry.
