I need to send a person to London for business for 3 months this summer: I think to buy a Skype IN number but which plan can I choose for mobile? He has a wifi toshiba notebook and a qtek 9100 (gsm-gprs- wifi). In Italy he uses vodafone but what can I choose for London? He needs to check email from our server in Italy and receive calls from europe (and to call across europe)

Thank you
