Elysia's? version of a mobile phone, basic Crystal-Operated Mobile Communication Devices (COMs for short) have been around for a couple of decades and offer basic telephone and text communication.

Standard COMs have a touchscreen interface. More expensive units also access the CORWW for instant messaging, email, and chat. Some newer units have video communication capabilities.

COMs aren't available for purchase yet in Nirim?, and aren't even allowed through the Zanaryan? portals. Characters hailing from Earth? might still refer to COMs as cell/mobile phones.
