I haven't looked in a while but IMO if you want this, the only feasible way is likely to go with carrying an internet hotspot and off-shoring 2/3/4G functionality. Ideally, a phone without the second processor is the only way to actually achieve this -- then you have "only" the chip hardware and wifi chips to deal with/secure.
