A communication device is a hardware component that enables a computer to send (transmit) and receive data, instructions, and information to and from one or more computers or mobile devices.
A friend of mine had this phone (I had it too). And there was this one time he was helping an old lady push her car while I was driving behind them to keep the traffic at bay. He dropped his phone and I drove over it. He came over, took a look at it, screamed and smashed it to the ground. We all had a good laugh.
OKI 700 - my first ever mobile from the mid 80s. I was a college student and did a deal with a retailer that meant i had 2 contracts on this phone but that I got the phone for free! Needless to say where did my student grant go?? Early days of geekdom indeed.
