How to check whether a phone is blacklisted
A phone with no signal is not necessarily blacklisted. Check the device identifier and ask the network to explain its status before deciding whether you can use, buy or sell it.
Start with the right kind of problem
A network blacklist concerns the handset's IMEI, rather than just your SIM or phone number. The GSMA explains that operators can block an IMEI and share device reports with other participating networks. A SIM bar, network lock and an Apple or Google account lock are separate issues.
Write down the exact error and when it started. No Service, SOS or failed calls can also involve coverage, an inactive plan or a SIM problem. Avoid treating one failed call as proof of a stolen-device report.
Find and check the device identifier privately
On an accessible iPhone, look in Settings, General, About. Apple lists other ways to find the identifier in its serial number and IMEI guide. On many phones, entering *#06# in the dialler displays the IMEI; Vodafone describes this in its lost-phone guidance.
Compare the number with your own purchase record where available. Some phones have more than one IMEI, so tell the network what the device displays. Keep these details private: provide them through the organisation's official support channel, rather than posting screenshots publicly.
Ask the network, and understand a report's limits
Contact your network provider and ask whether the problem is an IMEI block, account bar or service issue. GSMA directs consumers who dispute a block to their wireless provider, which can verify the account and recent network activity. Its Device Check service also supports industry organisations; do not assume that every public checker has identical access or coverage.
If a seller provides a report, check its date and identifier. A result describes information available at the time. It is not a substitute for ownership evidence, account-lock checks or an honest condition description.
Resolve a block through the reporting organisation
If your own recovered phone was reported missing, ask the reporting network what evidence it needs. Insurance can affect the next step: Vodafone's recovered-device policy distinguishes devices with an insurance replacement from those without one.
If a second-hand purchase is flagged, contact the seller and relevant provider. Keep the receipt and correspondence. A factory reset, new SIM or network-unlock request does not establish rightful ownership or remove a blacklist.
Before making a selling enquiry
Resolve ownership and network status before offering the phone for sale. Give EXE the model, storage, condition and any remaining issue accurately. Never describe an unresolved handset as fully working, and do not share passwords or verification codes. An enquiry is reviewed individually and does not guarantee acceptance.
