Are you struggling with a bad ESN? ESN refers to a unique electronic serial number manufacturers use to identify a device.

ESN is quite important as this number can be employed for locking your smartphone in the case of theft.

All you need to do is contact your network provider, who will block it immediately. Sometimes, ESN can even be used to track your device’s spare parts if required.

Part 1: Everything You Need to Understand About Bad ESN

You may find several listings about a bad ESN and a good ESN. Now, you might be thinking about what all does it mean? Here’s detailed information on a bad ESN.

1. What is a Bad Esn on the Phone?

ESN is given to a smartphone employed with a CDMA phone rather than a SIM card. A bad ESN usually means users cannot activate their phones on their existing carriers.

If you purchase a phone with a bad ESN from a person who has used the device on Verizon, for instance, you would not be able to activate the device on the same carrier, that is, Verizon.

2. What Triggers a Bad ESN?

If your device features a bad ESN, the device cannot build a connection to the same carrier network. Normally, when a phone is recognized with a bad ESN, there could be various causes. Some of these common causes are as follows:

  • The phone has been reported as lost or stolen.
  • The phone is involved in some illegal activity.
  • The account linked to your phone has unpaid phone bills.

3. Are ESN and IMEI The Same Thing?

Today, mobile service providers use two leading network technologies across the globe, which are:

  • Code Division Multiple Access (CDMA)
  • Global System for Mobiles (GSM)

The smartphones are designed to support CDMA or GSM, but not both. Smartphone manufacturers assign every phone a unique identification number depending on the technology it supports.

The GSM identification number is called an International Mobile Equipment Identity, whereas CDMA is an Electronic Serial Number (ESN).

4. How to Recognize a Bad ESN Phone?

Cell phone providers report a bad ESN if a phone has been reported as stolen or lost. Also, they will report the device if the earlier account holder used to have an excellent balance.

Well-reputed resellers can check ESN service before selling their device. However, phones bought from a private supplier are sometimes reported as stolen.

When you suspect the ESN of your phone, it is best to check the same online. ESNs are found on your phone’s back, in the phone’s settings, or next to the phone’s battery.

Contact the network carrier directly if there is no error in the ESN service. A network carrier might not provide the account’s information but can tell if the suspension was ever made.
