I was thinking about this today after running out of minutes, only being left with unlimited mobile to mobile minutes. I realized my phone card is useless as its only good for international calls and despite being toll-free it would still use airtime. Wouldn't it be great to have a number in your network to call that would connect you to an out of network number? Someone with the developmental brains could come up with something mimicking grandcentral or a phone card and then route it through their cellphone. In the long run you're saving tons of money and whoever is running it is making a lot of money by charging less per minute on overages than the carrier.
