What is the track record for Ekit, in terms of the likelihood of their going belly-up, like Celtrek apparently has just done?

I strongly suggest that you get the SIMple Plus card indicated above. It is $9+$3shipping=$12 versus $20 +$3=$23 for the Passport. The SIMple card has the _SAME_ rates as the Passport for Greece and Costa Rica and cheaper rates in the USA [so you can test it?! or set up voicemail] before you go. Be sure you use the eBay seller ekitmobileusa for the SIMple card.
I have been using various ekit cards for over 3 years and their web interface and customer service is excellent.
