GUwonder,

Maybe you could expand on that a little bit.

I know Airalo has their own brand of single country and region sims as well as 7 & 30 day versions of each of those. In addition they market a variation of the "Sim4Crew" service that is data only. Do you have details about variations in service by country, region or duration of service? I'm going to Spain in March and would be interested in hearing more about what you've experienced from their plans. The Airalo website claims they use Vodaphone service in Spain, for instance. I thought they had pretty good coverage there.
