Jul 23, 2020 at 18:30 comment added phoog @JimCullen maybe. But I've never heard the term T9 keyboard or even T9 before reading this question, so YMMV.
Jul 20, 2020 at 22:57 comment added Jim Cullen This answer may not be correct in a technical, official sense. But it is correct in a colloquial sense. I know I for one see that layout and my first thought is that it's a "T9 keyboard". When OP's goal is to install such a keyboard on their smartphone, I suspect searching T9 keyboard is likely to be the most fruitful option.
Jul 20, 2020 at 18:01 comment added Canadian Yankee @crizzis - Yes, that's why I said that you "sometimes" see it referred to as a T9 keyboard. However, the pre-text-messaging keypads did not have a Q or a Z on them (because there was no need to represent every letter).
Jul 20, 2020 at 16:04 comment added phoog @crizzis no, I was thinking more of the PEnnslyvania 6-5000 numbers.
Jul 20, 2020 at 16:00 comment added crizzis @phoog Oh, right, like those '1-800-SUMMERSALE' premium-rate numbers. I just realized I remember those as well. I guess I'm old

Jul 20, 2020 at 15:50 comment added phoog @AlexanderRevo indeed, the design of this keypad predates T9 by roughly 35 years. (Also, the layout is different from that of a standard computer numeric keypad.)
Jul 20, 2020 at 15:29 comment added Alexander Revo This answer is wrong: not all phones with such keypads had T9 (predictive) input. You just had to click through the buttons to get letters you needed. T9 is just a software feature to make using the hardware (keyboard) easier.

Jul 20, 2020 at 12:05 comment added crizzis This answer is a bit misleading. Not all phones with the telephone keypad also had the option to use T9 as an input method (in fact, I remember the T9 feature being a late addition to pre-smartphone-era mobile phones)
