Can someone tell me how to use the t9 text messaging?

Answer 1

It's easy. Just spell the word. For instance with
the word BAT you would hit B then A then T. The word won't look like the word your trying to spell unill you type the last letter.

Every letter you hit, the program makes a guess using its internal dictionary what word your trying to spell.

Withoug T9 you would have to hit the AB key twice then wait then hit AB key again then hit T. It's super fast; that's why you want to use it.

Answer 2

T9:

When spelling a word, tap each key once for each letter in the word. Ex. Phone = 7-4-6-6-3.
Alternate words will be displayed on the screen as a list. Use the Joystick to select the desired word. Press Continue or insert a Space to choose the desired word.

I ask someone in the past about this question on the site that I listed in my source. They have a cool section where you can ask them any question about a cell phone in their contact area.
