I just received my new blackberry 7130c, and I'm a newbie with blackberries.I have an ATT sim card and when I turned it on, things seemed OK except the network coverage that says 'network:*none* '. I noticed that turning on the wireless "Turn wireless On", enabled it to connect to my ATT network. However, and this is my biggest concern, by turning the wireless on, am I using my network coverage(ATT regular network coverage) or is this connecting online to an internet connection? I do not have a internet/data plan on my ATT phone plan. I do not want to use this facility and incur a ridiculous bill at the end of the month if this is the case. Is there a way of connecting to my regular ATT network coverage without turning on the wireless device? PLEASE ADVICE.
