It is actually unlimited? Several companies in the United States offer "unlimited data" but throttle speeds after you use 50 GB~ so much that it is basically unusable.
Unlimited has to be unlimited by law. After 10gb of usage a day, you need to text a number (for free) to get a few more gb, and so on. That's just there to prevent flooding the network too much.
From what I have heard it depends on the mobile provider. Some have daily limit around 10+ GB. But that seems quite reasonable.
I have monthly 10GB 4G for my phone and I have never hit it.
I've heard stories after a screw up the mobile provider gave unlimited 4G for a year and the guy used it as his internet at his home.
