How do I unlock my Samsung illusion sch-I110
There are website who charge users and generate Unlock Codes to unlock their Smart Phones to work with any Sim-Card.
So I have a att note 2 running DN4 rom 4.4.4.
I requested a unlock code from att. Tried to enter unlock code ,unlock unsuccessful message appears .
Tried some steps I found online but still nothing.
When I dial *#197328640# it says connection problem invalid mmi code.
I'm using an active t-mobile card to unlock device.
