Okay so I have a mytouch 4g, as everyone knows, the battery life isn't good at all on this phone. Anyway, my phone's service is off as of now, I downloaded the textplus app yesterday. I understand wifi has to be on in order for you to use it. But what I wanna know is, say if I turn wifi off when I don't use my phone(when i'm in class) would i get the text notifications while my wifi is off and just not be able to text back.? Or would i get them as soon as i connect to wifi and click on the textplus app.? Or would I only receive the texts that are sent to me while I'm connected to wifi.. 
I can be connected to wifi at all times on campus, but again, my battery dies fast which is why i'm not really willing to leave wifi on when I'm not in my dorm.
