I don't understand the need for minutes while traveling, I'm using 99% data, 1% voice. Maybe that not the usual pattern? For the few voice calls I do make, I use skype for $0.05/min or free to other skype users. Just like your regular phone you can also take skype calls just as easily for a similar rate.
