Prepaid device unlock after 6 months
I'm submitting a request to unlock my iPhone6 after 6 months, every it responds "Your device hasn't been active for 6 months.". The device has been active for 6 months, there are no reason provided why the request being rejected everytime.
I got iPhone 6 on 3/26 & got it activated in at&t store. I had to travel outside the country for a month, Would like to know the actual criteria to activate my phone. I have waited untill completion of 6 months, but the unlock request id being rejected.
