Will vodafone UK make a greater profit with, or without roaming charges?

T-Mobile, Telefonica, etc, are likely to be adversely affected if they don´t announce similar, or even better, promotions. Vodafone´s immediate customer gain may be the other networks´ long-term loss.

The voip companies and the international phone card companies are likely to be losers. The (mobile) voip bloggers (Jeff Pulver, Andy Abramson, Dan York, etc) have not (yet) commented on the new vodafone UK promotion. But let´s be realistic -- who will search for voip wifi access, if they don´t have to pay anything extra (i.e. no roaming charges) to make or receive calls on their normal european cell phones? The vodafone UK promotion, if continued indefinitely, might be so successful that it kills the "mobile voip" mass market in Europe, before it even takes off! Well, at least until cheaper roaming data tariffs become available.
