BusinessWeek's Olga Kharif today looks at Vonage's plans to start offering wireless services during the second half of 2007. "The company also expects to announce new agreements to resell other carriers' Broadband Internet access services, as well as other content deals later this year," she writes.

The expectation, Kharif says, is that Vonage will become a mobile virtual network operator (MVNO), possibly even renaming itself Vonage Wireless. "While Vonage won't divulge any details, it did confirm after its Feb. 15 fourth-quarter earnings call with analysts that it will start selling dual-mode phones offering cellular as well as Wi-Fi access in the second half of the year," she writes.

GigaOM's Om Malik is skeptical. "Given the trials and tribulations of MVNOs, that road is full of potholes the size of a Hummer!" he writes. "It will take tens of millions of dollars to get a cellular-Wi-Fi MVNO rolling. Whatever move the company makes, it is a desperate move by a desperate company, which is seeing its subscriber growth slow down."
