Re: IF YOUR SPRINT Samsung SPH-A640 HAS REJECTED A TEXT MESSAGE....
You can't. If the message is not in your inbox after clearing out previous text (in and out), pictures, and etc to obtain enough memory then that message is simply not there.
You could also power off the phone for two minutes after clearing memory, remove the battery, then place the battery back in and turn it on, however again if that message is not there then the one who sent it will have to re-send.
