The first mobile phone I ever bought was the Motorola StarTAC.
As you can see, this was a ‘flip’ phone that closed down to a small and manageable size. The flip action also terminated the call, making sure that you were not still connected by mistake.
The SIM card was the size of a credit card, and slid into a narrow slot on the phone.
It had no camera.
It could not connect to the Internet
It could only make calls and send a text.
It never failed to connect, and stay connected.
Any call made on it was as clear as anything, and never fuzzy or muffled.
You only had to extend the short aerial to always guarantee a signal. (At least in London, where I lived at the time).
I had it on a ‘Pay and Go’ deal, where I topped up the amount I needed. No monthly fee.
The battery lasted for days on end.
I don’t know where it is now, or even if it would still work.
But I wish I had never upgraded from it.
