My uncle brings me a t-mobile Galaxy S3 t999 with android 4.3 (t999uvuenc2) phone from USA to Iran. BUT as you guess its locked to t-mobile sims. So the question is, how to unlock it to use sim cards available in iran?
I've already tried some methods, like *#197328640# and no success gained! there is no option as " NV INITIALIZZ"
What is the easiest and cheapest way to unlock it?
Can anyone share his knowledge with me or point to the tutorial if available? Thanks...
