wifi usage and my home internet

30 GB? That doesn't sound right at all.

 

I can't imagine getting more than 5 GB in a month unless you're doing something like streaming radio or watching online videos pretty much all the time.

But that seems like something you'd remember.

You can go into the phone's settings and then into General and "Usage." That will tell you how much data you've received from that cellular network.

It does NOT count Wifi, but you said you use the cell network more, right? So if that says something like 2 or 3 GB then you can be pretty sure you didn't rack up 30 GB on wifi!

Question: Do you have a password on the network? Could your neighbors be watching netflix movies non-stop using your open wifi network?

 

Daisy, make sure you restrict your WiFi to only your use. Sometimes your neighbors will join your WiFi, b/c you don't have a WEP password setup. B/C 30GB is too much for one month.....

 

Contact your ISP to make sure it's not a billing error. If it isn't, then either someone in your house has been downloading loads of stuff you don't know about (e.g. movies) or as others have suggested you have a neighbour leeching on your Wifi. Set up WPA2 encryption on your wireless network (and MAC address filtering if it'll support it).
