I inserted a new SIM card in my Samsung smartphone and now it's asking me for a PIN to unlock it. How can I unlock my device?

Region Lock


Some Samsung smartphones, such as the Galaxy Note II, Note 3 and S4, are designed to work only with SIM cards issued from mobile networks from a certain region (this region should normally be found on your device's packaging). Should the device activate with a SIM card from a different region the device will lock automatically and you will need to speak to Samsung customer support regarding unlocking the phone so it can be used with that SIM card. Customer support contact details are here.


Network Lock


If your device locks when used with a SIM card from a region authorised for that device then it strongly suggests that device has been locked by a mobile network to only work with that network's SIM cards.


Samsung does not lock any of its devices to any particular network. You will need to contact the original service provider or retailer for your handset to request an unlock code. This is not something that Samsung can do on your behalf. 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.
