Data only prepaid for Europe
 

I am going to Austria and Hungary for around 9 days. I don't need to make or receive calls and only need data.

Rather than have to buy 2 separate sims in those countries, I am looking to get a global sim. Has anyone used Keepgo? In searching, it seems like the best deal to me. For $6/day you get 100mb a day and they ship the sim to my house. There are no sim charges or other fees (other than $8 shipping). I also like that you put in the countries you need and dates and they automatically activate for those days so there is nothing to do once on the trip (going to website or making calls to activate).

It seems like many of the other companies require a bigger investment, topping off, etc. and may be better suited for longer trips.
