There are those type of users who left their favorite device in the trusting hands of the specialists, who not only overcharged their service rarely managed to permanently unlock a device and in the process caused the termination of your cell phone’s warranty.
Some people when they faced the same circumstances as you are now have tried different sorts of methods. I mean, you can’t just go at the carrier’s branch office and ask them to remove the lock on your phone, you can’t end the agreement if you are not willing to pay a lot, you can’t runaway- they have a lot of your personal information, so in short there is really so very little that you can do about your locked device.
So, when you come to think of it your situation is not that great after all.
