SMS Issue Resolved (Google Voice) Android 4.3 CM 10.2
After flashing CyanogenMod 10.2 stable release, I was experiencing problems with my sprint galaxy s3 regarding SMS. I thought it had something to do with my google voice account, because the 10.2 family includes voice+ for google voice users. Well, it turns out it did. After doing many things and wiping and factory reseting many times, I tried deactivating my google voice number to see if that would work. After I did that, my text messages immediately started working. The problem was solved.
I have not yet tried to re-activate my google voice account and use 10.2 stable. Hope I could help somebody out.
