My wife receives "Error 97: SMS origination denied" whenever she tries to text me. I don't receive them. It started a few weeks back. She can call me fine. I can send texts to her, and she can text other people fine. According to the My Verison page, neither of us have any call/text blocking turned on. If I'm on a group chat with her and other people (MMS), I receive her messages, but not SMS.
We've both restarted our phones. Based on a forum post, I removed the SIM and powered down, then inserted it and started it. No effect. The messages also do not appear on my text messages list in the online msg viewer, so I don't believe it is a messaging app problem. She has a LG K 20 V and I have a Moto G2, both Verizon and both fully updated.
