 How can I solve the network lock issue on my Galaxy phone?

Answer:

Identify the problem: A network lock (also known as NCK or Network Control Key) or subsidy unlock is a code assigned to your Galaxy phone by your mobile service provider. This prevents your phone from working on any other network aside from your current one.

Contact your service provider: If your Galaxy phone has a network lock, reach out to your mobile service provider for guidance and assistance. They will be able to provide you with an unlock code or guide you through the process of unlocking your phone.

Terms:

Network lock (NCK or Network Control Key): A code that restricts your Galaxy phone to work only on its original network.

Subsidy unlock: Another term for network lock, referring to the practice of releasing a phone's restrictions when the user completes their contract or fulfills certain requirements.
