Yes, Marko, I have been to London multiple times working in football. You just have to arrange with your carrier before you go. The cost is about $10/day, and it works just like being home. You only get charged the $10 "IF" you place a call or send your first text for the day. I forgot one of those subsequent times, but because I had it set up in the past (with my carrier), I got a pleasant surprise when I re-enabled my phone from airplane mode upon landing at Heathrow. You get a text reminding you that this feature is turned on. I don't recall the exact language of the text. There was no mention of a SIM card, however. We just called Verizon (or Comcast, I forget which), and they just set up our account to handle this.
