This is a good check
before you buy any phone, especially second hand ones.
If phone is SIM locked you may not be able to switch to other operator.
Here is how to activate the menu:
<**<
Lock to Network? if pressing yes you have 5 attempts to enter NCK.
<**<<
Lock to Network subset? if pressing yes you have 5 attempts to enter NSCK.
WARNING
Your phone can be locked to a service provider FOREVER by doing this! If
an invalid code is entered all five times, the menu will exit and be deactivated!
Any further attempt to activate the NCK/NSCK lock Menu will result in the
response "Not allowed"!
