Phone trouble! Kyocera loft not recieving texts.?

[Luis]

I've owned it for 3 months, never dropped it or any damage at all. However every time i receive a text it turns into an email... I've gotten my sisters phone and texted mine, every time i get her text it opens up the "im and email" app. but no new emails no new ims, and no new texts. Its gotten annoying because i keep getting loud beeps when the app activates even when on silence. oh and i dont receive any of my texts =p. Help?
