I concur with what rfranzq said - The need for international sims has reduced drastically! I would guess that most users of these sims are not based in the EU. As you mentioned, EU based travelers will just use their sims, since they can roam at local rates. Plus, all the 4 major US carriers offer some form of roaming package , that make these sims not worthwhile, especially for short trips. For me, my primary travels are to London, and Nigeria. And I have local sims to use there.
