I recently purchased a new nokia 3620 from eBay. The phone was unlocked when I bought it. The problem now is that I cannot use any sevices specific to my network. I cannot use the internet or download ring tones. The only things I can do are use the phone and send and receive text messages.
So I guess my question is how do I go about setting the phone up for my network. I know there are unlock codes. Are the "lock" codes?
