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

 

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.

 


 

 

Unlock PIN (Personal Identification Number)

PIN is set to prevent unauthorized user to access your SIM.

 

If your device locks when used with a SIM card and requesting for PIN code, simply insert your PIN code to unlock your SIM card.

 

A new SIM card usually comes with a temporary default PIN of 0123 or 1234.

 

*Important Note*

SIM card will be blocked if you enter incorrect PIN code for 3 times.

Once SIM has been blocked, it will request for PUK code.

 

If you does not have your PIN / PUK code, you have to contact your Mobile Network Operators (Telcos) to obtain your PIN / PUK code.

 

Samsung customer support regarding unlocking the phone so it can be used with that SIM card. Customer support contact details are here.
