I already have a 3G phone mate. Am on the Vodafone UMTS network here in Germany.
The coverage here should be decent enough, I hope! I also have a Vodafone Zuhause chip, which basically acts as a home phone in my handset, with a range of up to 2KM. Gives me greatly reduced call costs from my mobile. I think they're trying to compete with home phones and VoIP. That works fine and uses the same underlying 3G network.
