Your phone’s IMEI (International Mobile Equipment Identity) number is an international serial number for your phone to properly identify it. The IMEI number is used by networks to identify valid phones and block stolen or blacklisted phones from accessing the network.
So what does your IMEI number do? Well first of all it is considered the unique serial number of your phone. With the IMEI number you can keep track of your phone. For example, if it gets stolen, you can enter your IMEI number into a free global database and when your phone is found, the IMEI number then can be used to contact you.
Use your IMEI number to unlock your phone. For instance, if you are looking for a permanent iPhone 5 unlock, you use your IMEI number and an iPhone unlock service and unlock your phone. Unlocking your phone has many benefits such as switching SIM card when travelling from country to country and avoiding being overcharged or it will increase the price of your phone if you are attempting to sell it.
Your IMEI can also be used to check what network your phone is with. If you’ve recently purchased a second-hand phone, use a network checker to see what network the phone is currently locked to. You then know if you should unlock your phone.
Your IMEI number isn’t just a number. It provides security for your phone and is its thumb print. Your phone is identified by its IMEI number and it’s useful when you’ve purchased a second-hand phone and when wanting to unlock it.
