How to unlock a blacklisted iPhone 4?

I bought an iPhone 4 online, wasn't told it was blacklisted however so it doesn't make calls/texts. I have no method of contacting the original owner, so that's out of the question. How can I unlock the phone, or the imei?

Once an insurance company has paid out, the phone is legally their property.
Let them know, and they'll probably let you buy it back at a reduced rate.

We can unlock handsets which have been barred or reported as lost or stolen. There will be an additional charge to unlock barred handsets of $50.00. You can check if your handset is barred prior to purchase by going to www.checkmend.com/us

Please be aware however that if the handset is reported as lost or stolen, then it will only work outside the country it was barred in (as the networks share the lost and stolen database and will refuse service).

If its AT&T, hire a company to unlock it remotely. Its cheap and fast and works even with blacklisted iphones…

  • Unlock Blacklisted iPhone 5? I found this iPhone 5 two years ago and the owner never responded to my calls or emails so I soon forgot about the phone. Now I broke my own iPhone and remembered the one I had found, when I turned it on I checked the IMEI number and found it to be blocked. My question is there anyway that I can unlock it and use it?
  • Is it possible to unlock a blacklisted IPhone 5? I have this phone that I bought on ebay, although I only notice after a month or so, they told me that the phone I bought is stolen and had a bad ESN. Immediately I tried to find out if it was possible to return and get a refund, unfortunately I can't. My only options left is whether I can sell it or possibly unlock it. Can I use the phone overseas?
