I am using the Blackberry 8700g moblie with no data plan, I am using a prepaid sim card. I had noticed that everytime I connect to internet Im being charged.
I am also wondering why cant I detect my wireless router at home. I have tried to manualy scan all available networks but still cant find my home router. Do I need a prepaid load to access the internet, and what should I do inorder for me to detect my home router... thank you in advance!

Probably because the 8700 doesn't have WiFi.
