How do I get a Signature at the bottom of my Text message?

Hi

I like to have a signature at the bottom of my text message is there any way to keep it there instead of downloading a app every time I want it there.    My other phone all you had to do was go into the settings and change it to what ever you wanted it to say.   I cant find it on this phone.

Please let me know as soon as possible.

Thank you very much,

Yolanda

Under mail there's a signature under settings. I don't see for text.
