Yep, that's the one. It was my first cell phone as well. With 4 watts it never dropped a call. And the echo echo echo echo.
I've personally never really had a cell phone, I did have use of a Nextel for a short period, but never really used it, except the walkie talkie feature, so I have never found need to get one.
I do remember however, my dad, (he retired from telephone) had a "mobile phone" back in the mid/early 60s. a Motorola unit, took up about 3 cubic feet in the trunk of his company car, (I think it mighta had vacuum tubes in it) and the telephone unit on the cars dash, had mechanical buttons that converted to dial pulse, regular looking handset, but had a PTT button on it. Ringer was hooked to the car's horn when he was away from the car. 100 watts iirc, there weren't many repeater towers back then
