Skype and Nokia today announced a partnership that will bring the world's leading Internet communications experience to the Nokia range of mobile computers. Under the terms of the cooperation, Skype™ will be integrated into Nokia devices, starting with the Nokia Nseries. The Nokia N97 flagship device will be the first to incorporate the Skype experience in the 3rd quarter of 2009.
This might make waves. It may force network providers to rethink their dataplans. a lot of UK based providers simply block the ports used by voip services unless the customer is on the top (most expensive) data plan.
Depending on how Skype and Nokia market this, network providers may find themselves having to develop specific plans with these handsets in mind. The reason a lot of providers block VOIP is because it theoreticaly removes the need for users to make calls using traditional methods. All calling can be done over the web.
The issue I see for providers is "fit for purpose intended". If the phone is capable of doing something, will the provicders be able to offer it unless it can do it on their network. In other words can the providers offer a phone without all its features usable.
