I don't think the EU has ever had net-neutrality as you'd call it in the US. The infrastructure and internet service are separated in most places which has similar outcomes. (and mobile data is wicked cheap for other reasons)

Most notably, this means a bunch of stuff gets "zero-rated" (e.g. free unlimited facebook/whatsapp with any phone plan, but other data is limited), which was explicitly called out as anti-competitive when the fight was going on about net neutrality in the states.
