Unhappy [Q] Cannot Receive SMS Text Only

Just today stopped receiving all SMS texts. Spent over an hour with AT&T, guess what happened there.... anyways.....

I can send texts fine, recipients all get my texts promptly
This happened just today, all day, in multiple areas, full or half battery,2/3/4 out of 4 bars, in/out of wifi range, etc...
AT&T had me uninstall GO SMS Pro which I did reluctantly, and of course fixed nothing
I get texts on Kik/Whatsapp fine from 4G/LTE and wifi just fine
On Android 4.3 still, heard they up to 4.4.2, but this only stopped working today, so not sure if thats relevant
Havent had time to upgrade my CM but I know I should, but again I dont think my texts sending have anything to do with that all of a sudden today, although I thought it was curious AT&T told me their new Android update came out today, tremendous coincidence.

Any thought/suggestions/experiences?
