so, I've just bought my first touchscreen phone... it came with a SIM card, Norton security, other bundle stuff like that.
I've mucked around with it and I see that I can use both my home WiFi and mobile data to access websites ... and I'm curious what exactly I'm paying for this. -- when I go to settings/device/status, it doesn't even list my phone as having a phone number ("unknown"), I'm not sure what to do about that. was I sold some sort of pre-paid data with my SIM card or something? I don't understand why it's not really a 'phone' yet, but I apparently can run up data usage.
also, curious what the most accurate gauge of that usage is--I think some settings tell me WiFi usage, and others only tell me mobile data usage, or something, because sometimes it says 0kb used, sometimes 90kb used, sometimes 200mb used (I think the latter is when I was browsing apps through WiFi). is there a good app for android that says where your data usage came from (not which apps, but what source--wifi or mobile data?)
