What this advice cannot do
Two limits apply to every page on this site, whoever wrote them. Nothing here is legal advice. And this site does not query the GSMA registry or any carrier database, so it cannot see whether an IMEI is really blacklisted — only the carrier can. What it does is tell you which lock your symptoms point to and who holds it.
How the site is funded
REPLACE THIS PARAGRAPH BEFORE PUBLISHING. You did not supply any wording for this section, so nothing has been written for it. Describe the funding accurately — if the site earns from the advertising shown before the detailed steps, say so plainly. Readers work it out anyway, and a site whose argument is “we tell you the truth” cannot afford to be vague about its own money. Delete this box once the paragraph is written.
UnlockBlacklisted sells no unlocking or blacklist-removal service, takes no commission from one, and links to none.
Corrections
Carrier procedures and device line-ups change constantly, and some of what is written here will go out of date. If you find something wrong, please say so. Write to [email protected], or see the contact page.
