Replying to C DM: Yes, wifi calling was also available. These mobile hotspots are astonishing (within the limits to the amount of data you can use on a daily basis -- the number escapes me, but it wasn't an impediment; on the other hand, I wouldn't stream a movie while on the road). They fit in a coat pocket, and you can order a vehicle charger or a spare battery for an extra fee in addition to the wall charger that comes with the unit. We went with the vehicle charger and were glad we did, as the wall charger process took hours. Also, some rental car companies provide their own version (I think Hertz does, for example, but we went with the other approach.) As for Gmouse's question, the my-webspot mobile hotspot is compatible with every phone, regardless of carrier, to the best of my knowledge. One final note -- if you can't use wifi calling for some reason, you may still need to add an overseas plan to your Verizon account for the duration of the trip. Check with your providers.
