Guys the Saudi Arabia SIM trick didn't worked.. I have just inserted the Indian SIM Card and it is again asking for SIM NETWORK UNLOCK PIN.. My perspective towards Samsung has changed now.. even Apple has never done something like this.. at least Apple was straight forward whether locked or unlocked..
Will contact Saudi Service center support tomorrow and if it dont go well then I will try the last resort Chainfire App..
You just have to enter it once. It costs around 1000 bucks maybe.
Second, I guess after inserting your saudi sim card install the region lock away app. And follow the instructions inside the app. After that if you will insert the indian sim card I think it will work.
