This post describes what is SIM network Unlock PIN code and how to get the Netwrork SIM unlock code from carrier or third-party services. Whether your phone is Samsung, Motorola, LG, or iPhone, this guide will get you covered!
SIM network unlock PIN, also known as network unlock code, is a unique code that is used to unlock a mobile phone from the network carrier's restrictions. When a phone is locked to a specific carrier, it can only be used with that carrier's SIM card. However, by entering the SIM Network Unlock PIN, the phone can be unlocked and used with SIM cards from other network carriers.
Therefore, with SIM network unlock PIN, you can unlock your phone from the network carrier's restrictions and use a SIM card from another network provider. The free network unlock code is typically provided by the original network carrier.
The SIM Network Unlock PIN may sometimes contain both an MCK code (Master Code) and an NCK code (Network Unlock Code), or just one or the other. Users are usually required to provide an IMEI number to the carrier in order to obtain the correct SIM Network Unlock PIN to unlock the phone's SIM card lock.
Note that the SIM network unlock PIN has nothing to do with the SIM PIN or PUK code. The SIM PIN and PUK code are used to protect your SIM card from unauthorized use on another device, while the SIM network unlock PIN is used to unlock your phone from the restrictions of the original network carrier and use it with a different network provider. These are two completely different things.
To unlock the device with a new SIM card from another carrier instead of the original network provider, you may need to get the SIM Network unlock PIN for free from the carrier.
