This was a reason I really hoped 3 would have won the contract.
It's great have 3 mobile broadband, being able to go to Italy, France, Spain etc, and take my broadband with me, and better still they do not charge you any extra for the usuage abroad.
I get 10GB for €19.99 per month (1.34mb download speed average) Made my recent trip to Italy a dream.
Shame my O2 mobile didn't do the same and ended up costing me over €120 in a week because of all the exhorbitant roaming charges... 🙁
