Is unlimited internet truly unlimited?
Technically, yes—but there’s a catch.
Unlimited internet means you can use as much data as you want. However, some providers may reduce your speeds (throttle) after a certain threshold, especially during network congestion.
Suddenlink/Optimum plans currently do not enforce data caps or throttle speeds under normal conditions.
