Note - If you bought your Nokia
on UK Vodafone or UK Cellnet you
do not need to check this
because they both transmit on
GSM900, and they don't lock the
phones. However if you bought
your phone on UK Orange or UK
One2one your phone may be
blocked. The reason is that they
both transmitt on GSM1800. To
make a call on GSM1800 you need
what is known as a "Dual band"
phone. A dual band phone is able
to transmit on both GSM900 and
GSM1800, so they lock the
phones so you can't use it with
any other network simcard. If
you find that your phone is
locked you can try different
software to unlock it. (we havn't
found one that works yet), or
you can ask your service
provider who will gladly
exchange the 10 digit code for
about £35.
This is how to check the status of
the 4 different locks. Aslo don't
try entering the wrong number,
because after 3 times it will block
the phone for good.
There are 4 different locks on
your Nokia phone.
COUNTRY-LOCK
NETWORK-LOCK
PROVIDER-LOCK
SIMCARD-LOCK

status of your phone is

The code has 10 digits, To read
out the sim-lock status you can
enter every combination you
want!
"Y" Shows the status of the
network-lock. Here you can enter
a number from
