Cosmote Greece

I've been using Vodafone where you get 8Gb for 10euro. It expires after 28 days but I rarely get that far anyway before needing a top up.
 
Don't think so, I've been using it since January. Just go into the shop when I need a top up, give them details of the SIM and when I get back to the boat the data has been reset at 8Gb
