Let's look at using the English language correctly. Would you say, "I lettered you?" No, you would say, "I sent you a letter." So, therefore you should say, "I sent you a text message." And don't forget to add the word message.

Why would you say, "I sent you a text?" A text what? A text book? So if we used proper English, we would simply say, "I sent you a text message." It's not that difficult. We are just dumbing down our society by accepting the use of the fictitious word, texted.
