During operations, the mobile phone may display the follow-
ing operating tips:
“Please Insert SIM”
You must insert the SIM card before using the mobile
phone. If the SIM card has been inserted, please get it out
and wipe clean with a dry cloth on the golden region, and
then insert the SIM card.
“Invalid SIM”
The SIM card of the mobile phone is locked and the insert-
ed SIM card is unable to be accepted. Please insert the cor-
rect SIM card or contact with the vendor.
„Please enter PUK”
The SIM card has been locked since the wrong PIN code has
been inputted for three times. You must consult your net-
work provider for the special PUK code with eight numbers
to unlock the SIM card (The PUK code may have been pro-
vided with your PIN code at the same time).
Warning:
The SIM card will be locked permanently if the wrong PUK
is entered for ten consecutive times. You must then apply
for a new SIM card from your network provider.
