This block of services is designed to unblock SAMSUNG models from carriers of different countries and from regional blocking. Before choosing a service, make sure that the device asks for a code and that you have correctly identified the type of blocking. In case of blocking on the carrier, an NCK code is required, in case of regional blocking, an RGCK code is required. The type of request on the screen does not indicate the type of lock. The MCK code is a reset of attempts in case of multiple input of incorrect codes. This code cannot be ordered separately. For more information on the types of blocking, see the information on the link.
You can check the type of blocking by checking the IMEI for Samsung
Depending on the type of blocking, select the service, the name of which contains the code you need. If you still have doubts about the choice of the service, consult the site support: support@imei-server.com or via Online chat.
