Paul is going to be traveling to Great Britain and wants to know how they can use data while out of the country. Is SkyRoam a good option? Leo says that SkyRoam is an interesting pay-as-you-go option when traveling. Google Fi is another, as is a MiFi card. Pay-as-you-go is nice because Paul would pay for only what he uses. He'd also want to be sure they support high speed data.
Paul should check out prepaidwithdata.wikia.com for the what is the best option for the countries he's going to visit.
