Telcos use the word unlimited too freely
Often what they really should say is "unfettered access" to the internet, anytime anyplace you have signal, NOT what we think it should mean " all the data stream we can use"
When they throttle the bandwidth they reduce the data flow, so they really are limiting how much data can be used,
Around here, mobile data gets really congested from rush hours thru early evening, I think it's too many people using navigation apps to get home , commute traffic is virtually same most days, traffic delays and accidents are common place, Waze can give you more info than you used to get from the car radio, but it IS still the same slow drive home,
commuting has been getting slower every year, watching the App screen real time traffic glut, won't speed up the drive home
Oops off topic, anyway that's my data use situation, every afternoon, forget internet .. Work on something, read, take a nap
