Here is what I have on my past usage:
2011
May: 9.4GB
June: 8.6GB
July: 4.6GB
August: 5.9GB
September: 6.7GB
October: 6.8GB
My wife used between 3.2GB and 4.5GB during that timeframe for each month.
We have the $30 grandfathered plan.
I am so happy I have unlimited
I commute 95mi to work; 190mi round trip. I stream podcasts and music for approx 4hr (commute), surf the web and check emails, some days I stream music at work as well.
What do you guys use data for so much?
1 to 2gb a month, grandfathered under AT&T unlimited, considering letting it go for the 4gb that includes tethering.
