You are also paying for truly unlimited data. Not like the 5GB cap or 10GB cap others have (even Sprint use to cap supposedly at 5GB before charging, though I've never gotten close to that).

The 4G fee is a "premium-data fee" which means you can litterally have 100GB or more if you want, of data and you will have 0$ extra charge. Tethering, using your 4G phone as your home internet, etc. is completely acceptable when there are no monthly bandwidth limits.

10$ a month for that is nothing, IMO though the 10$ is more for helping pay for more 4G towers and that stuff aint cheap. Early adopter fees :P

Still, I think it's perfectly acceptable. With all the extra charges, even on a regular plan, Sprint is by far the cheapest carrier out there.
