The test was on the operator www.elisa.fi

Most of their dataplans are unlimited (without any throttle).

Yea, my comments mostly apply to the USA. The rest of the world seems much saner when it comes to mobile pricing.

It could be that many of these companies want to keep the caps low so that you need to purchase both home internet and mobile internet. If I had a 100gb cap, I'd ditch my home DSL and simply use my phone as a hotspot all the time.

Here in Canada, Bell & Rogers own both the cellular networks and the home internet networks. They are highly incented to sell you BOTH.

That doesn’t make any sense. Here in the US, Verizon and AT&T don’t offer home Internet in the vast majority of the country, and Sprint and T-Mobile don’t offer it at all. The wireline divisions of AT&T and Verizon also make very little of the companies’ profits (Verizon’s wireline profit margin is typically 2-5%). Goldman Sachs has been trying to get Verizon to sell its wireline division for years. Why would it sandbag it’s wireless service to prop up its wireline division?

You're probably right. I'm just throwing out a hypothesis.

That depends on your provider; on my side, data caps have gone up a lot or have been lifted completely during the 4G era.

T-Mobile has 50gb throttle limit that’s only enforced during congestion.

Well, that's an improvement. I liked T-Mobile when I lived where they had coverage.

Meanwhile T-Mobile in Germany has a 4GB cap for 45 EUR/mo
