Remove my phone from blacklist this is my imel [Personal IMEI Information Removed]

Did you purchase it from a third party? If it was reported as stolen only the original owner can correct the issue. However, if it was reported as stolen and then an insurance claim was made there is nothing you can do. A common scam. Once blacklisted, it can't be used with any other carrier as well.

If you bought a used phone it's probably legitimately blacklisted has lost or stolen. You got scammed. Do what you can do to get your money back
