T-Mobile said today that hotspot subscribers can roam across the ocean. European subscribers can use hotspots in the U.S. and U.S. subscribers can use hotspots in Europe. Initially subscribers can use the overseas networks without an additional charge but according to a company spokesperson that will change. After a "limited time," international roaming fees will apply.
In other T-Mobile news, the company said it will build networks in US Airways Club locations. Washington National and San Francisco airports will get the networks first followed by Philadelphia, Boston, and New York's LaGuardia. T-Mobile took over offering Wi-Fi in American Airlines lounges when it acquired MobileStar's assets in early 2001, and later added Delta and United club lounges as well.
Neither press release seems to be posted yet but they should eventually be available here.
