I originally tried to contact Rogers to unlock my parents iPhone 6 but they wouldn't unlock it because it has not been on contract for a minimum of 90 days. We were leaving on vacation in 1 week so we needed the phone unlocked!
I used Keys2Iphone before going to Cellunlocker.net... big mistake! Keys2IPhone took 5 days and did not respond to my inquiries or emails. Then they finally responded saying the carrier would not allow them to unlock the phone?! What?!
So then I tried Cellunlocker.net and within 2 days they unlocked the phone! Amazing! Half the cost and they also respond to emails and inquiries really fast!
