Hi guys, any help would be great, I had my phone in another country (Taiwan to be exact) and I wanted to use the prepaid sim of Taiwan (I'm from the Philippines by the way), the phone works right and properly in my country but somehow when I loaded the sim from the carrier from Taiwan my phone asks me for something like a PIN number or something and then it doesn't proceed to any menu... as far as I recall that's the problem. Any information on why that is? Is my phone locked for my country's carrier or something? Any help to get rid of that PIN number do I need to get my phone rooted to disable that function? Thanks.
