I think we are going to have to agree to disagree here
Basically I've been using the EuropaSIM at 3 euro a day for 500 MB of data when I've been travelling outside of the UK and in Europe.
I have a dual SIM handset (Cubot x6) with my regular contract O2-UK SIM in it, and a Toggle Mobile SIM for cheap voice calls when I travel.
I then use the EuropaSIM in a Mifi (Alcatel Y800).
If I could pay £20.00 for a 1GB of multi-country data on my Toggle SIM, I'd jump at the chance, as it would mean I wouldn't have to take my MiFi with me.
As Bourbonkiller mentions, it really comes down to convenience. Obviously, if you're travelling to a European country without Toggle discount call/data facilities, then other choices become necessary.
I think the really interesting feature with Toggle is the US voice and data option, which can be a low-cost and convenient option for globe trotters.
