Three french cellular companies have agreed to allow roaming on their WiFi networks throughout France, according to this article from IDG Hong Kong.

The move is not too surprising considering the European GSM philosophy of having everybody roam on everybody else's network for reasonable prices. Unlike AT&T in the US, the Europeans have always had an aggressive roaming plan that allows smaller, more localized organizations to provide profitable services for their local consumers without locking them out of the national and international roaming ability.

It looks like the French have a good idea here, and we should seriously consider following suit.

The article also mentions that SFR already has agreements with Swisscom AG to have WiFi roaming on their network.
