Native Note 3 tethering works - if you have a tethering account. You don't need Fox-fi. If you don't have a tethering account, it's only a matter of time before Verizon's program is looking at your data when you're tethering some laptop or other device and you're caught, regardless of what app you're using. (It's not the app that does it, it's the data you're transferring that does. For instance. downloading an exe file [or a zip of an exe file] on a phone flags you as a potential tetherer. Then you get watched closely.)
