[Q] Must cycle Airplane mode between texts topic

I had CodeFire on my DNA for about a month. All was running well. I just installed whatever was current around 2/23 and never installed a nightly update. Last week, I started having problems texting. I thought the ROM was going belly up on me. So I flashed SlimKat. I still cannot text without cycling Airplane Mode in between each. Alternatively, I can wait about an hour to sent a subsequent test message after a successful one.

I just re-flashed the latest radio hoping that would fix it. I'm at a loss. Do I need to call VZW and have them do something on their end?
