In what can be seen likely as way T-Mobile will play in the USA when they get their 3G up and running this year, over in the UK T-Mobile just added free hotspot access to their Web N’ Walk 3G service offering, and in essence, have created a WiFi/3G bundle. This is the first I’ve heard of any mobile operator creating this type of offer and shows a keen sense of understanding that there is a market which always wants to stay connected.
It also lets me think that there may be a forthcoming 3G/WiFi Voice play coming from them that builds upon the T-Mobile@Home play that they are already offering in the USA.
I have used the Web N’Walk service on a pay as you go/pre-paid customer and like it.
