I lost my phone two days ago and purchased another phone off of craigslist (I am with ATT). I rooted, updated the recovery image, the new spl, and ROM.

Everything went great... except I could not send SMS messages. I found a solution with partial help from a forum post (I think on this forum) about someone using ANYCUT to create a homescreen shortcut to "Phone Info."

I used that shortcut to observe some settings with my phone. One suggestion was to turn off - then, back on - the radio. I did that without success.

Finally, I called ATT and was provided excellent customer support. The rep asked me if I had set my "SMSC." I replied that I had located a setting for the SMSC using the above shortcut - but, there was no number listed and I had no idea if the setting was correct.

He provided the following SMSC # +13123149810. I entered the number and selected the "update" button. PROBLEM SOLVED!

So, IF you have an ATT phone and you EVERYTHING works, except your SMS messages won't send... Try using the above shortcut method to enter that setting. If that doesn't work call ATT and find out if the SMSC number is the same for an HTC device in your area.
