What is IMEI number?
IMEI stands for "International Mobile Equipment Identity". It’s a 14 to 16 digits long number and it’s unique for every iPhone and it’s the identification of your device. The IMEI is much like a Social Security Number, but for phones. An iPhone can’t be used with a different SIM card unless you make a visit to the Apple Store or where ever the iPhone was purchased from. The IMEI thus also serves a security purpose.
What is an ESN?
ESN stands for "Electronic Serial Number" and it’s a unique number for each device that works as a way of identification of a CDMA device. In the U.S. there are some carriers that work on CDMA network: Verizon, Sprint, U.S. Cellular, so if you are with any of these carriers you have an ESN number attached to your device.
What is a Bad ESN?
A Bad ESN can mean a lot of things, let’s check out some examples:
- If you hear this term most probably you are trying to activate the device with a carrier, but that’s not possible due to some reasons.
- It can mean that the previous owner of the device switched carriers.
- The previous owner had an outstanding amount on their bill and cancelled the account without paying the bill first.
- The previous owner didn’t have a bill when they cancelled the account but they were still under a contract and if you cancel sooner than the due date for the contract, an "early termination fee" is created based on the remaining period of the contract and they hadn’t paid that amount.
- The person that sold you the phone or someone else who was the actual owner of the device reported the device as lost or stolen.
What is a blacklisted IMEI?
Blacklisted IMEI is basically the same thing as Bad ESN but for devices that work on CDMA networks, like Verizon or Sprint. In short, the main reason that a device has a Blacklisted IMEI is so that you as the owner or someone else cannot activate the device on any carrier, not even the original one, thus avoiding selling or stealing the phone.

How to find the IMEI or ESN numbers:
- On the original box of the iPhone, usually around the barcode.
- In Settings, if you go to General > About, you can find the IMEI or ESN.
- On some iPhones, it's in the SIM card tray when you pull it out.
- Some iPhones have it engraved on the back of the case.
- If you dial *#06# on your dial pad you will get the IMEI or ESN.
How to verify if your iPhone is blacklisted?
- There is an online tool wherein you can verify this. This is a highly recommended source to check the status of your phone because it’s quick, reliable and offers no fuss. You just go to the page, enter the IMEI or ESN, enter your contact details, and you’ll soon receive all the information you need!.
- Another way is to contact the carrier that the iPhone was initially sold from. Finding out is easy, just look for a logo: on the box of the iPhone, on the back case of it and even on the screen of the iPhone as it boots up. Just look for any carrier, Verizon, Sprint, T-Mobile, etc.
Ask the seller for a refund
If you bought the device with the bad ESN newly from a retailer or online shop, you might be in luck as they can provide you with a refund or at least a replacement, depending on their policy. For example, Amazon and eBay have refund policies. Unfortunately, if you got the phone from someone you found on the street, or from a seller over sources like Craigslist, this might not be possible. But there are still other things you can do.
Use it as a gaming console or iPod
Smartphones have a whole lot of functionality besides being able to place calls. You can install a bunch of different video games in it, you can use it to surf the internet, watch videos over YouTube, download music and videos to it. You could even use it as an iPod. The possibilities are really endless. You can even install apps like Skype and use Skype call as an alternative to a phone call.
Get the IMEI or ESN Cleaned
Depending on your carrier, you can see if they entertain requests to remove your IMEI from the blacklist.
Swap the Logic Board
The thing about a blacklisted IMEI is that it’s only blacklisted in a particular country. An unlocked AT&T iPhone blacklisted in the US would still function in Australia on another network. As such you can try and change the chips of your iPhone. However, in doing so you should be prepared for some possible irreparable damage.
Unlock it and then Sell it
After your unlock your iPhone you can sell it to foreigners at a lowered rate. You can find out how to unlock in the next steps. But why would foreigners buy a blacklisted phone, you might ask? That’s because they won’t be on US soil long, and the IMEI is only blacklisted locally. So foreigners and tourists might be persuaded to buy your iPhone if you throw in a big enough discount.
Take it apart and sell the spare parts
You can dismember the logic board, screen, dock connector and back casing, and sell them separately. These may be used to help out other broken iPhones.
As mentioned earlier, you can unlock the phone with the blacklisted IMEI. However, since it’s only blacklisted locally, you can sell it internationally where it would still have value.
Flash phone to another carrier
This is an ideal option for those who don’t mind changing carriers. You can flash the phone to another carrier, as long as they accept it, and pretty soon you’ll have a functional phone! However, in some cases, you might land with a 3G connection instead of a 4G.
Determine Hybrid GSM/CDMA Phones
If your phone cannot activate on a CDMA carrier like Verizon or Sprint, the IMEI can still be used on a GSM network. Most phones manufactured these days come with a GSM standard nano or micro sim card slot and have GSM radio enabling for a GSM network. Most of them also come factory unlocked as well.
Having a phone with bad ESN or blacklisted IMEI is naturally a headache, however, all hope isn’t lost. You can do any of the things mentioned in the previous steps, and you can read on to find out how to unlock the phone with bad ESN or blacklisted IMEI.
