How to openline
A gsm can be locked the SIM card is NEVER locked!!
The SIM itself is
never locked: you can use it in any compatible unlocked cellular phone.
There are 3 different kinds of simcards for mobile phones. Two 2G
cards; a 1.8 Volt version and 3.6 Volt version. All newer sims are 3.6V
versions. Some real old phones (older then the year 2000) have trouble
handling the new simcards. Next to this you now also have the uSim(also
referred to as 128k sim), this is a special simcard for UMTS phones and
has more space to save contacts and text messages.
Different kind of locks.
are different kind of simlocks, this depends on the brand but there are
a couple common kinds of locks which are often used.
Sim lock -> Locked to 1 simcard
Operator lock -> locked to one operator (provider)
Password lock -> GID lock you have to have a code to unlock this lock.
locks are 'Wap lock', 'Mp3 lock'. Sometimes the names of the different
locks are just different. For example; the term NCK code is same as
network (operator) unlock code.
Note: a 'security code' or a 'user
lock' is not a simlock! It is like a pin code only then not saved on the
simcard but on your phone. This is usually a 5 digit number which the
user of the phone has to set. This code can however also be reset by SRS
