A small detail I’ve been thinking about regarding the Pokemon world is how many devices there are to make calls. You got Silph’s Pokegear, Devon Corp’s Pokenav, Unova’s Xtransciever, and Lysandre Labs’ Holo Caster. Also considering the fact that Poketches can’t make calls, Pokegears are probably prevalent throughout Sinnoh as well.
What I’m thinking is that all these devices are bound to run off the same network. It’s just not plausible to have a world of travelling trainers and have different communication tools that are incapable of registering friends who use different devices. Also some of the devices seem to be more communication-oriented like the Xtransciever and Holo Caster whereas the Pokenav and Pokenav Plus are obviously more suited for navigation.
