Never been throttled on my personal account. I thank Pandora Radio, Slacker, Google Maps and my favorite weather widget for pushing me over this threshold month after month.
I have users on my business account who have exceeded their 200 MB plan and yes they've been throttled to some insane dial up speeds. A quick call to upgrade their plan to the unlimited no overages plan usually fixes this problem really fast.
Whether or not we admit it, the more sophisticated our apps become and the faster our wireless broadband is we're going to hit these caps much faster.
“The Internet wasn’t meant to be metered in bits and bytes, so it’s insane that wireless companies are still making you buy it this way. The rate plan is dead — it’s a fossil from a time when wireless was metered by every call or text.” John Legere 1/5/2017
