What to do when your Samsung galaxy phone is Network locked? This article will provide you with different methods to unlock your Samsung Galaxy phone. 

How to know if your Samsung Galaxy Phone is locked to a network?

Samsung does not lock any of its devices to any particular network. You will need to contact the original service provider or retailer to request an unlock code.

Some service providers may allow you to unlock the device for a small charge or for free, whereas others may not allow the device to be unlocked at all.

Insert a SIM card of a different network in your Samsung phone and then turn it on. It will show you one of the following messages if it is locked to a specific network:

  • "Network lock"
  • "SIM network unlock PIN"
  • "SIM password"
  • "SP lock"
  • "Phone freezes SIM unavailable"

You cannot unlock your Samsung phone using unlock codes if the Phone is hard-locked. 

If the phone is hard locked, it will show you the message "Network lock with an SOS or Dismiss button."
