Well I still don't get it cause this morning I saw two text not send the circle was still spinning from yesterday. I set my handcent now to tell me the message is sent but I never had this problem before on my 3D or my OG EVO. Last night most of my text went right through but one then I saw today that one and one from earlier in the afternoon didn't. My signal when not on wifi sucks in my house so maybe that's it I don't know. Even though I know text don't use 3g or wifi.

So any of those apps are the same and should work under 1x cellular.
Google Voice to the extent that you haven't combined your numbers uses data so it has the possibility of being less reliable when at 1x, but more reliable if your cell service is bad but you have wifi.
