[Different how? It's nearly on the tip of Kunsel's tongue to ask, but Terra probably needs more information first before he could give a decent answer. So instead, Kunsel reaches around to tap a button on the device.]

Each person who has one of these has their own number, and you can record those numbers, along with their name, if you want. It makes it faster to call them, and you don't have to keep their number memorized. Here- [Another button tap.] -you can read old messages people have sent, or delete it if it isn't important to you. Some PHS's can access specific networks, too, but they have to be set up for that first.

[He pauses, checking to make sure that Terra got all that. If he's seen something like a PHS before, he might well have had no problem.]

Any questions so far?
