What is SIM lock?

Last Update Date : Jan 08. 2018

SIM lock is the highest security provision of this handset.
If you activate SIM lock, then you can use only that SIM (which is present
during SIM lock activity)  with your handset. If you insert any other SIM, then you need to provide the SIM lock password.

If you forget the password, then you will need to visit Samsung Authorized
Service Centre to unlock it.
