I had never heard of DeFi until today and now I’m using their service and REALLY liking it.  DeFi is geared to international callers and heavy talkers.  They offer unlimited mobile VOIP or mVOIP calls to anywhere in the world (on Nokia S60 phones) as long as you’re on wifi for $40/month.  I call that impressive.  This is great for travelers who don’t want to pay ridiculous roaming fees just for making calls.  If these guys can get the word out to everyone I think they will do some serious disrupting.

Thanks to Tim for taking his time to tell me all about the service.
