The IMEI number refers to the 15-digit code that’s assigned to all smartphone users. The number is used to collect the basic information about the device, including the origin of the smartphone, the manufacturer of the device, the model number, and other details. You could use the IMEI number of the device to get your mobile blocked by the network provider should you lose your smartphone. Any device can be blocked as long as you know the IMEI number. You could also use the IMEI code to unlock your device on different networks.
If you ever get your phone locked, you must provide the IMEI code to the network provider to have it unlocked. The question is where do you get the IMEI code or how can you generate one? There are plenty of free IMEI unlock code generator tools available online. Note that your IMEI number will not be functional until it is unlocked. If it is locked with a certain network, you are going to have to unlock the code to be able to use it on other networks. The IMEI unlock code generator could be used to retrieve just about any code on your device. Once you have unlocked your IMEI number, you could use any network on your phone.
