You would never have seen this had the merger between at&t and T-Mobile been finalized. I always thought the free Wi-Fi calling was huge when out of the country. I've been a T-Mobile customer for almost a decade and have been happy with them.

I have a feeling this will not be matched by any of the other carriers, or if they do there will be a host of additional surcharges that will negate any real savings. This enhancement really took me by surprise, and a pleasant surprise. Nice to see a company adding value to an existing product.
