Unlimited data SIM explanation please

[NickJoh_2993198]

I have the unlimited data SIM plan, and am looking for a proper explanation of what this actually means. I have read the "fair usage" policy and this is where things get fuzzy. Smarty say tethering 8 devices constitutes a breach, yet the data SIM only plan states unlimited tethering in the UK, which is it? Then, does unlimited really mean unlimited?

@NickJoh_2993198  Replied on your other post. If they say that tethering 8 appliances is considered unreasonable, then that does seem fairly clear.

The problem is that someone downloading large amounts of data contributes to congestion for others on the network who are using smaller amounts - and that, put simply, ain't fair play!

The point is, the plan states unlimited tethering, so 2 different statements does not seem fairly clear.
