This article seems overly deferent, the tech prowess required for making this an actual pleasant and workable experience for $135 or so isn't obviously easy to obtain. The article implies that "it's not like customers are speculating on this" because they have units "almost" ready to ship. That's dubious -- nobody has tried one of these things. Just anecdotally, my experience using portable wifi hotspots, like the products from CLEAR or Boost Mobile, suggests that having a pleasant calling experience on one of these things is far from a guarantee. Getting voice calls to feel and sound non-annoying over some type of relayed data connection in a foreign country is a non-trivial problem to solve and there's no real actual evidence in this article that they've solved it. With that said I sure hope they do, I would find this product very useful. But it seems like the jury is very much out.
