Older 3G modems pretended to by Hayes compatible and pretended to be talking PPP. However PPP is terminated in the modem itself. It is not spoken over the 3GPP networks. These are purely IP. And yes, in theory there was a dialup in GSM, but I don't know of any users. Even early 9600 baud communication was RLP based. And for modern things like LTE it is IP all the way (including voice). What some modems still do today is pretend they are Ethernet devices. That is faked by the modem as well and mainly for some odd Windows crap. However many modern modems give you the raw IP stream. You just have to ask nicely.
