After entering the code, press the Left Function Key to
confirm.
Warning: If you enter an incorrect PIN code three
times in a row, the SIM card will be locked. You
might unlock the card by entering the PUK code. If
you enter the incorrect PUK ten times, the SIM
Card will be permanently locked.
Then, after the first initial use of the SIM Card (or after
restoring to the factory settings) an option to enter the
current date and time will appear, as well as an opportunity
to copy Contacts from the SIM Card onto the phone. Enter
the correct time using the numeric keys, press the key
DOWN, and follow the same steps to enter the date, and
press the Left Function Key. To navigate between digits,
press the keys Right/Left. If you miss setting the time/date
(Return), the phone will get the data automatically from the
GSM network.
Then, the question will appear: Copy All from SIM to
Phone? Select YES, if you want to copy all Contacts from
the SIM Card onto the phone. Otherwise, press NO.
