Better than that, Doug has a collection of cell phones from various other worlds (especially early 21st century Earths) -- the reason for getting a 1992 cell phone is to get the SIM card to put in something newer for her. I didn't want to stretch believability by having him make a SIM from scratch and then hack it into the system.
DoCoMo didn't launch its 2G service until 1993, so you're going to be limited in which phones can talk to the networks.
The phones they were selling were carrier-locked, too, but that might be more easily hacked around. They probably won't have removable SIM cards, though - that's a GSM thing, and GSM was Europe-only at this point.
