I seem to recall that something similar as this case happened in Sweden (10+ years ago?), where a operator was forced to not claim "unlimited data" unless it truly is unlimited and without throttling, but I can't find any references to this right now...
Does it really matter if they change their branding to be unmetered rather than unlimited?
No, not honestly.
There is a natural "hard cap", though. If you're paying for a certain speed, then the natural limit would be however much data you can pump at that speed over a set period of time.
I think it would be fair to call that "unlimited", in the sense that the service provider would not be imposing an artificial lower limit from what physics allows.
If a service provider isn't allowing that, then it's hard to see how they can characterize a service as "unlimited" without it being an outright lie.
Most people aren’t upset about network management throttling, but about the deceptive advertising that says you get unlimited, but in fine print: “limited to EDGE speeds (128Kb/s) after 2 GB”
The problem is that mobile operators are incredibly underprovisioned. If your plan offers 1 GB of LTE data, at 35 Mbps, you can burn through a monthly allocation in 3.8 minutes. That's an average utilization of 0.0087%, or an underprovisioning by a factor of 11,500.
They sell it as if you're buying 35 Mbps access to the network all month long, when really, you can't use that for more than a few hours even on 'unlimited' plans.
I don't expect 1:1 access so that everyone can use their full bandwidth full time; I don't want to pay hundreds of dollars a month for that. But I'd pay a tenth of that for 1:10 underprovisioned access, and I'm sure that plenty would pay a few cents for the current 1:10,000 underprovisioned service...
Not good enough?
In my view, the entire problem is that they want so badly to say "unlimited" while at the same time not allowing actual unlimited use.
The problem could be easily resolved at no cost -- all the companies have to do is stop using the word "unlimited".
