Is this a total scam?
On the website, it says they accomplish this by
What we can do is replace the IMEI number of the blacklisted phone with an IMEI number from a phone that is not blacklisted. We have a stock pile of salvage phones that are damaged beyond repair and we use the IMEI numbers from those phones to replace the blacklisted IMEI of your phone.
ONCE WE RECEIVE YOUR PAYMENT, A RECEIPT WILL BE SENT TO YOUR EMAIL. ON THAT RECEIPT, NEXT TO THE SERVICE DESCRIPTION, YOU WILL SEE A "DOWNLOAD FILE" LINK. CLICK ON THAT LINK AND THE INSTRUCTIONS ON HOW TO SETUP YOUR COMPUTER AND PHONE WILL DOWNLOAD TO YOUR COMPUTER. THEN SETUP YOUR COMPUTER AND PHONE PER THE INSTRUCTIONS. IT TAKES ABOUT 5 MINUTES. THE SETUP PROCESS IS SIMPLE. THE NON-TECHNICAL USER WAS KEPT IN MIND WHEN CREATING THE INSTRUCTIONS. IF YOU CAN DOWNLOAD AND INSTALL A FILE, YOU CAN DO IT! AFTER COMPLETING THE SETUP PROCESS ONE OF OUR SERVICE TECHS WILL CONNECT WITH YOU AND REPAIR YOUR IMEI. IT IS THAT SIMPLE!
