Well, most Cricket ones do an actual dial out to a server like dialup, the only difference is you go through a tower instead of a land line. If you ever look at the stream for the interface, it's not very different from very low quality DSL, it's more like a typical 56k modem, but, digital instead of analog, that's why I said it's vastly different from 3g/4g. 3g/4g do a different form of dial out entirely though, they are more like a wifi device, being purely digital from my understanding, hence the reason I mentioned Wifi earlier compared to what really cheap services offer.
