I’ve got an unlimited data plan with T-Mobile! But guess what? After you’ve used five GB of data the speed is limited to a point where it takes an unlimited amount of time to download something.
The concept of unlimited data requiring infinite time probably seems funny to T-Mobile marketers who promote the “unlimited” plan. (“A new sucker is born every minute, just like Barnum said!”)
If you’re planning a podcast about the future collision between the Milky Way and Andromeda galaxies, I suggest you post it now, so when the event occurs in five or six billion years, T-Mobile customers will have had sufficient time to download it.
