T-Mobile has at last linked its US and European hotspot networks to allow subscribers based in either territory to continue using the service when the travel to the other.

Something of a no-brainer, you might think. But only now has the Deutsche Telekom subsidiary managed to connect European and US billing and access systems to let the usernames and passwords of subscribers from one zone to be recognised in the other.

The move opens up over 4100 US hotspots to European travellers and will enable US customers to access more than 700 locations in the UK, Austria, the Czech Republic, Germany, and the Netherlands.

Separately, T-Mobile USA has signed a deal with US Airways to add hotspots to the airline's airport lounges. ®
