GNex with Jellybean won't send SMS

view story

http://forums.androidcentral.com – This morning, out of the blue, I can't send text messages on my Nexus. I've tried using my preferred app (GOsms Pro) and the stock messaging app with same result. I've rebooted. I've pulled the battery and sim card. Still no luck. I can make phone calls no problem. Data usage for web and apps is working fine. Even tried changing network mode from LTE/CDMA to CDMA and back and still no luck. I love this phone, but this is greatly frustrating. I haven't contacted Verizon Support yet, saving that as a last resort. I did some googling first but only found results from people discussing simil (HowTos)
