Hi or hola to Argentina.

All of your countries are within the EU where Roam like at home rules are applied (see European Union ). So generally, we suggest to buy a SIM card in the first country you visit and use it in all other countries at the domestic rate (of the 1st country).

Is your point of entry to Europe in Germany? Then you should check out Germany chapter. It's a bit tricky for some visitors from overseas to register a SIM card here. Telekom is sometimes not willing to register some countries especially online. So you might try it in one of their stores. Your best choice is Vodafone Germany with good 4G roaming in all other countries. Just go to one of their sales points in Germany and make the registration there showing your passport. Stay away from O2 as you don't get 4G/LTE roaming, only 3G on prepaid.

Or is your first country Austria as you have posted your question in the Austrian chapter? Here, it's much easier to get a SIM card, as no registration is necessary yet. But Austria doesn't make so much sense if it's at the 2nd part of your journey. In Austria go to Drei (3) as A1 and many resellers don't offer 4G roaming for prepaid and T-Mobile wants to see a registration for roaming.
