Limbaugh advertises PureTalk
I looked at it, but PureTalk is a repackaging of AT&T services, while Mint is a re-packaging of T-Mobile Services.
In the trade-offs between the two, IMO... T-Mobile are not the bad guys... (which is only partially, and in small part, but not entirely about the tech on offer ? )
It boils down to who you trust the least.
Or, perhaps for Mr. Limbaugh... who is paying him for the nod.
