I'm going on a poker world tour and I will be in various different countries for relatively short periods at a time. I'll have my laptop with me and I want to be playing a lot of online poker from whatever beach I happen to be lying on.
Is there any option for me to be able to do this easily, either through some sort of 3G internet or something? Even if I have to get a different provider per continent or something - can anyone offer advise on this please?
