I don't think the stats are that relevant, at least for romania. For example I pay 6 eur/month for a prepaid sim that has something like 2k minutes and sms, and 6 gb of traffic. The thing is that my carrier (Orange) always offers an extra 50gb of traffic for free. Afaik, most carriers have a deal like this. The quality is decent, they have 4G coverage almost everywhere, maybe except in the mountain areas, but that's to be expected.
