A&T iPhone Unlock Problems of “ SIM Not Supported ”
The problem comes to both ordinary users and companies that specialize in factory unlocking iPhone 5S / 5 / 5c / 4S / 4 by IMEI number. Ordinary iDevice owners often contact AT&T on their own after their contract expires asking for the free service. Here is how it should work.
AT&T iPhone Unlock Troubleshooting Story
As mentioned last November by 9to5Mac, the problem began last year. Back in the fall 2013 a lot of resellers had to close their business because AT&T iPhones could no longer be unlocked. These handsets are popular across the world because of the frequencies used by this American carrier that are good to be used in many foreign countries. AT&T iPhone unlock policy was changed at that time causing problems, delays and unlock fails. The new rules became strict and complicated for everyone in the market. Some business owners were forced to leave the market. Others had to adjust asking their customers for patience. As WSJ noted, AT&T didn’t change its policy for individual unlocks. Customers can still request this service after the contract has ended [but we see that this practice also experiences big problems nowadays]. AT&T unlock issues with resellers began with the higher unlocking price. The U.S. company said it would unlock the cell phones at the price of $100 instead of $1 or $2 they used to get for the same mass-unlock service. Why has the carrier changed its policy? It is not clear and no one can answer this question. AT&T itself does not unlock devices that are still on contract. Third-party companies do. Yes, they experience problems with iPhone 5S / 5C / 5 unlock, delays and sometimes fails, but a lot of their requests are fulfilled and successful making customers happy.AT&T iPhone Unlock Delay
Different sources and forums mention AT&T iPhone unlock issues in the end of 2013 and early 2014. Delays are not the biggest problems since you can be still unlocked, even with the status delivery delay while others cannot.
