Hi all;

I’m brand new to this forum and I need help unlocking an iPhone 6 with these specs:

Model: IPHONE 6 MM 64GB GOLD
Find My iPhone: ON
iCloud Status: LOST
Blacklist Status: Blacklisted
Estimated Purchase Date: 09.06.15
Coverage End Date: 09.06.16
Product Sold by: AT&TCOMERCIALIZACIONMOVILSDERLDECV

I’m looking for a reliable service provider who can unlock this at a reasonable cost.
Can anyone here help?

Thanks…
