I have a ascend mate 2 4g and it is locked to consumer celluar. When i called to activate it on the screen of the phone it said enter sim service provider block? so i asked them in the phone and they gave me 3 unlock codes none of them worked i even used a 3 party provider and payed and got three move unlock codes. I am so confused and all i want to do is use the phone it wont even work with consumer celluar. It was working fine and had service when i got it when i tried to unlock it then stopped working and asked for the sim service provider block.
