Spoke to a rep today. She said that there is no way to tell if towers are highly congested. What she said to me that I found interesting is that they attach a certain code to each unlimited plan. If your plan is not attached to this code then they won't throttle you. She also said you must meet all the criteria and to be in the to 5% of all users, you would have to use more than 100 gigs a month to even be close to the top. Do I trust this, kind of, but we will see. I told her that I was going to just switch to straight talk...she replied..they throttle too...and I replied...they throttle at a 100 bucks less a month so if im being throttled I might as well save my money. hopefully this wont affect too many of you.
