I dunno in the Live Action Sailor Moon, they actually had Cellphones that worked as normal ones as well as allowed them access to special Senshi-Only things. Primarily a type of "Disguise Power". The design kinda matched the Senshi bracelets however. Though I think that was intentional, still. That and Sailor Luna used her Cell to transform. She punched in a code and then became Sailor Luna.... just like the Tamers do for nearly everything.
If you have no idea wtf I'm talking about, I has proof. lol

And yeah, I got one too. >_> XD
