It's a BIG SCAM
Purchased iCloud activation service and after 2 days I got an email from them saying my device is blacklisted which is not.
I saw a great number of reviews having the same problem with the same excuse "Blacklisted device", so if you haven't dealt with them yet, just don't. If you unfortunately did and they used the "blacklisted story" you can check you IMEI in this site (swappa. Com/esn but without space) it works if you're in the US but you can use a VPN for that very easily. Also, if the activation screen on your device is showing the first letter of an email (such as s****@gmail.com), this means your device is not blacklisted.

Oh yeah, I have to mention they won't do REFUND. This is a quote from the email they send me
"How to obtain a card refund
If you have proof the device is not lost/stolen e.g. the original invoice from Apple or your carrier, either electronic or physical" which makes it obvious that they are big scammers because if the customer has the original invoice, he/she would not come to you in the first place.

Finally, I will say it again, if you haven't dealt with them yet (iphoneIMEI.net) then DO NOT
