This never used to happen (I've had this phone on this plan for about a year and a half) but in the last few weeks, I've been having issues sending and receiving pictures. Restarting my phone (Samsung Galaxy Nexus) seems to fix it but only temporarily, seems to be for about a day. And then the next time someone sends me a picture, I get the notification but it shows nothing in messaging, does't even look like the tried to send one. If *I* try to send one, I get the message "couldn't be downloaded, please try again later." I'm on the $15 pre-paid plan, unlimited text/picture/video messaging.
