I've been having this problem since I got the phone, even after the latest software update. About 50% of the time, texts sent to me never arrive. Another thing is, when I do receive SMS about half the time there is no notification whatsoever. Meaning, it does not appear in the bar nor does it make any sound or vibrate. I have all these settings turned on in the messaging app and have tried toggling them on and off as well as resetting the data/cache and deleting my entire inbox. Anyone else having this problem or know a solution? EDIT: As far as the not receiving texts thing, I also tried dialing *228 and updating roaming capabilities a couple times with no improvement.
