First there was BRB, LOL, and now…IMEI. Okay, so you probably haven’t used IMEI the way you might use “LOL”. Unlike internet slang, knowing what your IMEI number is and what it’s good for could actually help you save on your wireless plan. 
In this essay, er, blog we will define what is an IMEI number, what it’s useful for, and how it affects your compatibility with other wireless carriers like, say, Ultra Mobile, and some other helpful tips and tricks.

What does IMEI mean?

IMEI stands for International Mobile Equipment Identity. Similar to how your car has a VIN number, nearly all mobile devices come with their own unique IMEI number. And it’s a good thing, because it helps keep your phone securely connected to a network. 

4 cool things an IMEI can do: track device, block stolen device, identify devices, prevent counterfeit devices

What is an IMEI used for?

An IMEI number is a 15-digit identification number that is unique to each device and can be used in the following ways:

  • Device Tracking and Recovery: In the unfortunate situation of a device’s theft or loss, the IMEI number can be used to track and potentially recover the device.
  • Blocking Stolen Devices: Some wireless carriers can use the IMEI to block stolen devices from accessing networks, making them unusable for unauthorized users. Take that, bad guys. 
  • Identifying Devices for Repairs or Warranty: Your IMEI number helps manufacturers and service providers identify specific devices for troubleshooting, repairs, or warranty claims.
  • Preventing Fraud: IMEI verification prevents the use of cloned or counterfeit devices, protecting consumers and carriers alike.

What is IMEI compatibility?

IMEI compatibility is the process of determining whether a mobile device, identified by its unique IMEI number, is compatible with a specific carrier’s network. So if you wanted to bring your current device to a new wireless carrier like Ultra Mobile, you would want to check your IMEI compatibility to make sure your phone works with your new Ultra Mobile plan. And with plans as low as $10/mo, why wouldn’t you want to switch? But back to IMEI compatibility. 

How it works

  1. Device Identification:
    • The IMEI contains information about the device’s model, manufacturer, and supported network technologies (for example: GSM, LTE, 5G).
  2. Network Compatibility Check:
    • Carriers use the IMEI to verify whether a device supports the network frequencies and technologies they operate on.
  3. Lock Status:
    • IMEI can indicate whether the device is locked to a specific carrier or unlocked for use on multiple networks. Usually, when your phone is locked to a specific carrier it’s locked until it is paid off to the network it was purchased from. You can learn more about unlocked phones here.

How to find your IMEI number

If you want to find the IMEI number on your device, there are a few different ways, depending on the brand, device type, and model. Here are some easy ways to find it: 

  • Dial Code: On your phone, dial *#06#. Your IMEI number will pop up on the screen instantly. This method works on most mobile phones and is the quickest way to find your IMEI.
  • Phone’s Settings: Navigate to your phone’s settings. On most devices, it’s found under ‘About Phone’ or ‘Device Information’. This section often provides detailed information about your device, including the IMEI.
  • Physical Device: Sometimes, the IMEI is printed on a label under the battery or on the back of the phone. If you have an older phone with a removable battery, you can find the IMEI on a sticker beneath it.
  • SIM Card Tray: On some phones, such as iPhones, the IMEI number can be located inside the SIM card tray. It’s important to keep this number safe to prevent theft and misuse of the device.
