Network Lock

If you originally received your device from one network provider and your new SIM card is from a different network, the original network provider may have locked the device to their 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.
