Vonage said Wednesday that it was partnering with British Wi-Fi provider The Cloud to offer its customers free service at any hotspot operated by the company. Owners of Vonage's mobile Wi-Fi phone would be able to use the service, the company said. The size of a large mobile phone, the $140 handset allows a Vonage subscriber to make calls anywhere with a wireless Internet connection.

The Wi-Fi service would be free to those who already pay Vonage a $14.25 per month fee to place calls to U.K and Ireland phone numbers. The Cloud has nine hotspots around the UK, with satellite service points in airports, transit stations, coffee shops, hotels, and college campuses.
