Sony Ericsson Walkman (ATT) won't send text messages.?

[wowthankslove]

I used to not have this problem. My phone sent and received text messages without a problem. Now, all of the sudden, my phone won't send them anymore. Instead of sending them, the phone puts them directly into the "outbox" folder. I can still receive them from other people, however.

I've re-set my phone, but to no avail.
Does anyone know what could be wrong?

Thanks!

Did anyone figure it out - same happened to me. I switched it off for about 5 mins and then it sorted itself out, but it's been switching itself off after sending a text now and again for the past few weeks so i'm just waiting for the roblem to come back again.
