got the nokia c3- 2 days ago, I'm with Chat R, i can call, text, and everything. But when i try connecting to the internet it says "temporary network problem" .."Link is not available". I don't understand why this is, I've successfully connected to my WLAN and it shows on my phone that I am connected yet, it still says there's a network problem. Can you please tell me how to fix this problem. Your help is very much appreciated, and i really need to be able to use internet on my phone.
