I'm grandfathered into the unlimited data plan for AT&T. However, I did get to thinking, if I hit that ominous 3GB in a month. Would I just pay the extra $10 for the extra GB of data without throttled speeds. The thinking being the throttled speeds would just be too unbearable, even though it's still "unlimited data" And on top of that, I could add on the $20 tethering in a month I need it. (Mostly for traveling home where my parents don't have an internet connection) So I was just wondering if any grandfathered unlimited data users voluntarily switched to the tiered plans. (Specifically the $30, 3GB plan with each additional GB costing an extra $10 a month). And how's it gone, and do you regret it.
