Is the need for an "International" SIM Card ending?

don't think yet. although roaming has become cheaper providers have raised their price for roaming in non eu countries.

Lower roaming rates means less income so the will find a way to compensate this.
Dataroaming is still to expensive and it will take years before that will become cheaper.

Many of the cards offered here are also used by tourists from the usa or when going to the usa. and the free roaming card have many more free places where they roam.

Places outside the EU will never become cheap when you own say a dutch or german card. Why would they if they are not forced to offer low roaming for non eu countries.

So in the end it all comes down to a personal profile. Do you travel outside the eu, cards are still interesting. Do you travel withoing the eu and do you live in the eu, your local card could become more interesting.
Travel from outside euo into the eu, free roaming cards are still interesting
and so on
