That's true. Some providers are generous and add the US, Canada or even Brazil or Singapore to their home roaming zone. Others are very strict: O2 UK kicked out the Channel Isles or most providers in Germany and Austria exclude Switzerland, while it's stays included by most offers from France.

So roaming becomes very provider-specific. On Vodafone Germany you'll pay 500 times more using data in Switzerland than in Austria! This article shows the base = the minimal requiments that a provider has to give out at the domestic rate by law. In most of Western and Southern Europe only a few large packages will be capped; but in Eastern and Northern Europe some providers will still be allowed to apply surcharges from the first roaming MB.
