Sounds like another Vodafone product launched before it was fully tested!
Setting up my VMC card to send and receive e-mail was a very devil - I've now written an idiot's guide whcih the phone shop has distributed to all its branches!
And I'm still waiting to find out how to send e-mail from a VodafoneD2 hotspot in an airline lounge! I can send e-mails fine from UK Horizons hotspots in the UK - but VodafoneD2 hotspots in Lufthansa lounges always bounce any e-mail back to me.....
