me and my wife are visiting london in february for 2 weeks just wondering if i bring my unlocked phone which carrier over there is the best for unlimited data and text i really dont need many voice minutes as long as the data is unlimited i plan to use an unlocked android phone with an app to make free calls over my google voice on 3g or wifi

3 do an deal for £15 per month pay as you go. The deal has unlimited data allowance. I think you also get 3000 texts and 300 minutes voice calls.
