Not receiving some text messages

[soxfan5]

For the past couple weeks my phone has been missing some text messages, maybe 1 or 2 a day as far as I can tell. The messages show up as received on my usage details, but they never make it to my phone. I've had the phone for over 3 months and it has missed a few before, but it's never been this bad. Is anyone else having this problem?
