Skype's Eric Lagier, who heads up business development, said high data charges are the biggest barrier facing widespread uptake of wVoIP. The comment throws cold water on the growing speculation surrounding the release of Skype software for Nokia's 3G phones, which many attributed to Skype's getting bullish about wVoIP. Lagier is concerned that promoting mobile Skype as free will create backlash from the potential user base once it receives an outrageous mobile data bill for using it. Analysts point to U.K. carrier 3's recent move to offer unlimited mobile Internet service for a mere £5 a month as a step in the right direction toward a market friendly to wVoIP.
