Follow the below mentioned method, also see the advantages of T9 dictionary :
1.
Check your manual to learn more about text messaging
Check your cell phone's user manual to see if your cell phone has the T9 function. While most new phones contain this function, if you have an older phone, you'll want to check to be certain. Look under the Text Messaging section in the manual.
2.
Enable T9 for easy texting
Enable the T9 setting on your cell phone. Some phone require that you enable this function. Check under your cell phone's Options menu and also under the text messaging options. Depending on your cell phone, you may be able to set T9 as the default method of text input or you may have to toggle the text input functions to choose T9 for every text message. Generally, the toggle key will be your asterisk key. Again, check your cell phone's manual for more information.
3.
Choose your language and other preferences for T9 texting
Pick your T9 preferences. Your T9 function may allow you to set several preferences. The most typical preference is language, and you also may able to set whether you want your cell phone to use T9 for word completion only or to predict which word you will type next. You may also be able to set the "delay" - the amount of time before your T9 function changes the letters you are typing to what it thinks they should be. Again, try your Options or Preferences menus in the text messaging module of your cell phone or consult your cell phone's manual. You will want to try different set-ups to determine which works best for you and your style of text messaging.
4.
T9 gives you more then one way to select the right word for your text message
Type your text message, toggling for T9 if your phone requires it. Once the T9 function is enabled or toggled, simply type the word you want. Do not be concerned if the letters do not appear correctly when you first start typing the word - they will correct themselves when you finish typing the word, as long as you spell it correctly. Your phone may offer a drop-down menu with word suggestions as you type. If your word shows up, scroll down and select it if you wish or continue typing your word. If your phone does not offer a drop-down menu, and the word that you type is not the word that you wanted, press the Down arrow key on your cell phone and another word will show up. Keep pressing the Down arrow until your word shows up. When you have the word you want, use the space function to continue typing.
5.
Add your own text expressions to T9
Add your own words to the T9 function. The T9 function comes with an extensive dictionary, but you can add your own words or abbreviations, too. Again, you may have to dig around the Options or Preferences section in the text messaging module of your phone. Once you find it, simply type and add your own special words or expressions to have them at your fingertip when you text.
Use T9 to express yourself in your own unique way!

JUST READ THROUGH
Just wondering if anyone else was having issues with Microsoft Word from MS Office 2008, where you open the application, you type a few sentences, and the application freezes with the spinning circle of death that won't go away until you click the dock where it says "application not responding" and do a force-quit? You can leave the circle spinning for 10-20-30 minutes, and it never goes away.

Now for the weird part--this error only happens for me when I'm using a specific document on my computer. I can open Word, start a new document, type several paragraphs of text, and it works fine. But I've been working on an existing paper for about two months that all of a sudden started causing these freezes/crashes when editing it. It's about 30 pages roughly, no images, no big inserts that would take up a lot of memory (116 kb in size). And up until today, there were no problems. So why all of a sudden can't I edit anything on this paper without freezing the program?! I downloaded the Microsoft Office 2008 Service Pack 1 that was just released after this problem started, and ran all the recent Java and program updates through Software Update with computer restarts. I even copied the text from the Word document I was working on, pasted it into a new document, tried saving it as both .doc and .docx, and again the program still freezes when working with that text in a new file. This one baffles me. It's like the text within a document is somehow freezing the application. One thing I did notice is that the freezes seem to happen when I'm scrolling using a mouse wheel. Not always, but quite a bit. I suppose this is some memory issue related to several pages of text that the program can't render or process when you add new lines of text or scroll, but again, I can't figure why this paper I've been working on for months all of a sudden decided to start freezing Word today. Can you really only have 30 double-spaced pages of text in Word before it crashes?

Looks like I've found my reason to switch to Open Office, since I'm 3-4 days out from a

try to reset

Start-->System Tools -->Master Reset

I had the same problem, and it will only get worse. It's a simple fix though...just follow these steps. I actually found this solution on this exact website =] so if you can't fully understand how I explain it, ou can find other posts as well.

Settings >> Text Input Settings >> Uncheck box next to "Suggest Words When Typing."

Simple enough, restart the phone and start texting, It should be fine. Hope this helps!!

throw your phone.... hahahahahahaha

i would guess that when you droped it you knocked something loose is it still under a warenty? if so i would return it for a new one if not take it into a shop

The problem is autocomplete.. disable it and the text messaging will stop freezing. Just go into the same screen as if you're about to type up a text. Then follow these menu prompts "Options>Text Setup>Word Completion (Off)" That should help.

try deleting some text messages, especially your outbox and unused files on your phone.

probably is because your memory if full so you have to delete all the messages that they are store in your memory phone go to messages select options select delete all and that will be all
