support the receipt and display of this message type.

First you need to get into your phones setting, then touch the pannel for text messages and click get settings.

After you are in your settings there will be a pannel to put in your voice mail and text message number.

You then must go kill your self

I did more searching and found the answer! Clean out your inbox and outbox, and your phone should go back to sending normal messages. You might need to restart it afterward.

The phone allocates a certain amount of storage for messages on a whole. Even though there may still show space available for text messages, you have hit an invisible "limit" and the phone is now defaulting to MMS messages because there is "room" there. Delete a fair amount of messages and you should be able to start sending regular text's again.

Go to your message setup and there should be a place there to change that.
