In your country, do they offer unlimited Data across Europe, or only within your country? What is a price per month for such data plan/subscription? Do you need to buy a smartphone or SIM? Does the operator have a good application and support, as to update subscriptions quickly? Pretty sure there are differences across the EU, although they should not be, yet many say to check out individual country and get their number, instead of sticking to the country, where you now reside or live. What you say?
