For two years I had metered internet through an AT&T cellular modem. My data usage over that period averaged 14 GB per month and never exceded 15 GB per month. Two months ago, I switched to Exede. In the first month, my 12 GB data allotment was exhausted after 10 days (a rate of 36 GB per month). I increased my data plan to 18 GB, and the 18 GB was exhausted after 6 days (a rate of 90 GB per month), Why has my data usage increased 2.5 to 6-fold when I have not changed my internet use habits in any way? There is something very fishy about the way Exede meters data usage.
