(going to united kingdom)? Hey, I'm going to the United Kingdom from Canada for 4 months in two weeks. I was trying to see what coverage my plan will have will abroad (I have 3g right now, one year left of my contract, I'm with Telus). I checked the telus website, and it says that they don't have any service in the UK for 3g but they do for 4g. Is it possible to change from 3g to 4g within the same contract (even if I have to pay more)? I really need my phone while away. Thanks
