While unreliable it wouldn't be unrealistic to use wifi in densely populated areas. It looks like the pager industry is still alive, too.

Most wifi hotspots have location information anyway, so your phone will know where it is, and then one of the many apps on your phone can report back with that information.
And isn't a pager just a really simple cell phone? I'm not sure how that's a solution if cell towers can triangulate your position.
I should have been clearer: One way pagers seem to still exist. They do not transmit.
Isn't this just a billing distinction though? A 'receive only' pager still needs to announce itself to the cell tower to have messages routed...pretty sure they're not just multicast across the entire global cell network?

Dan Geer (CISO at In-Q-Tel, has been warning about the dangers of surveillance for years) has spoken about how he uses a pager instead of a cell phone.

I wonder if even an old iPod Touch withought a cellular chip would actually be a useful decice for this kind of wi-fi-only connectivity.
