Run a free IMEI check now: iPhoneIMEICheck.com/imei-check. Enter your 15-digit IMEI (dial *#06# to find it) and check the "Network Status" field in the results. A clean status means you're fine; "Blacklisted" or "Blocked" requires action.
What Does "Blacklisted" Mean for an iPhone?
A blacklisted IMEI means your iPhone's unique identifier has been flagged in one or more carrier databases, preventing it from connecting to mobile networks. Even with a valid SIM card inserted, a blacklisted phone typically cannot make calls, send texts, or use mobile data.
Blacklisting is a carrier-level action, not an Apple restriction. The iPhone still functions normally on Wi-Fi β apps work, iMessage over Wi-Fi works, FaceTime works β but cellular connectivity is blocked.
Common Causes of iPhone Blacklisting
1. Reported Stolen or Lost
The most common cause. When an iPhone owner reports their device stolen or lost to their carrier or police, the carrier submits the IMEI to shared blacklist databases. This is designed to deter theft β a stolen phone becomes useless on any network.
2. Non-Payment / Contract Default
If a device was purchased on a payment plan and payments stopped, the carrier may blacklist the IMEI. This is sometimes called a "financial blacklist" and differs from a stolen-device blacklist β it can often be resolved by settling the debt with the carrier.
3. Insurance Fraud
When someone files an insurance claim for a "lost" device and then sells it or continues using it, the carrier or insurer blacklists the IMEI. This is fraud, and buying such a device unknowingly puts you at a serious disadvantage.
4. Chargeback / Disputed Purchase
If a credit card chargeback was filed on a device purchase (buyer claims they never received it, then keeps it), the carrier may blacklist the IMEI when the transaction reverses.
How to Check If Your iPhone Is Blacklisted
Step 1: Find Your IMEI
Dial *#06# on your iPhone keypad. The 15-digit IMEI appears on screen immediately. Write it down or screenshot it.
Step 2: Run an IMEI Check
Use our free IMEI Checker to get an instant status report. The "Network Status" or "Blacklist Status" field in the results will indicate if the device is clean or flagged.
For a more comprehensive check covering multiple carrier databases, consider a paid service like IMEI.info or CheckMEND (see our IMEI checker comparison).
Step 3: Try a Different Carrier SIM
A practical real-world test: insert a SIM card from a different carrier. If the phone shows "No Service" or "Invalid SIM" regardless of which carrier you try, blacklisting (or carrier locking) is likely. If it works with some SIMs but not others, it may be a carrier lock issue rather than a blacklist.
Carrier Lock: Works only with one carrier's SIM. Unlockable through your carrier or a third-party service.
Blacklisted: Won't work with any carrier's SIM. Unlocking the carrier lock doesn't remove a blacklist. These are separate issues requiring separate solutions.
What Can You Do About a Blacklisted iPhone?
Option 1: Contact the Original Carrier (Best Route)
If the iPhone was blacklisted due to non-payment, contacting the carrier and settling the outstanding balance is the most reliable solution. Once the debt is cleared, most carriers will remove the IMEI from their blacklist within a few business days.
If the device was reported stolen and then recovered, the original owner must contact their carrier to remove the blacklist β no one else can do this on their behalf.
Option 2: Contact the Previous Owner
If you bought a used iPhone that turned out to be blacklisted, contact the seller. They may have unknowingly sold a device that was later reported, or they may be able to contact their carrier to resolve it. Always do this in writing to create a paper trail.
Option 3: Use the Device on Wi-Fi Only
A blacklisted iPhone still functions completely on Wi-Fi. If you're unable to resolve the blacklist, the device can still be used for apps, iMessage (over Wi-Fi), FaceTime, browsing, games, and more β just not for cellular calls or data.
Option 4: "Blacklist Removal" Services β Proceed with Extreme Caution
Numerous online services claim to remove IMEI blacklists for a fee. The reality is nuanced:
- Legitimate: Some services can resolve financial blacklists by working with carriers directly β but only for devices where the debt has already been settled.
- Scam: Many services take your money and do nothing, or temporarily manipulate check results without actually removing the block.
- Illegal in some cases: Attempting to remove a stolen-device blacklist is illegal in many countries and constitutes receiving stolen goods.
Never pay for blacklist removal without fully understanding the cause of the blacklist first.
How to Protect Yourself When Buying Used
The best defense is prevention. Before buying any used iPhone:
- β Run an IMEI check before paying β not after
- β Have the seller dial *#06# in your presence to confirm the IMEI shown matches the device
- β Cross-check the IMEI with the one printed on the box
- β Verify Find My iPhone is disabled (Settings β [Apple ID] β Find My)
- β Pay via a method that offers buyer protection (credit card, PayPal Goods & Services)
- β Meet in a public place and test the device with your own SIM before completing the sale

Frequently Asked Questions
Carrier blacklists are often regional. A device blacklisted in the US may still work on carriers in other countries β and vice versa. However, major international blacklist sharing (through organisations like the GSMA's IMEI database) means some blocks do apply globally. This varies by country and carrier.
Your carrier blacklists the old phone's IMEI. If the stolen device turns up later, you (the original owner) can contact your carrier to remove the blacklist β but only you can do this. Anyone else who has the device cannot remove the block.
No. A factory reset does not change the IMEI and has zero effect on carrier blacklists. The blacklist is stored in carrier databases linked to the IMEI, not on the device itself.
