I am also a victim of this so called 'upgrade' to the KitKat OS and was extremely frustrated that there never seemed to be an adequate response from Verizon in how to solve the problems that it was creating. I tried the solution listed here as the 'answer' to the original post, tried switching to airplane mode, tried the Hangouts app, then the Verizon Messaging App, shut the phone off, etc, etc, etc. And after reading about some of the problems that people were experiencing after a hard reset, I decided not to go that route. I did end up downloading the Textra app and am now able to send and receive MMS messages again. I even like how some aspects of this app works over the others.
Just as a note to Verizon... yes, this is an issue at the Google level, since they're the ones that created this piece of garbage, but given the HUGE outcry from your customers (and the fact that the 'fix' may take months to roll out to LG customers), you would think there would be some kind of proactive way to keep them informed. Personally, I was looking for ANY KIND of communication from Verizon acknowledging that they were aware of the problems and what they knew about resolving them, suggested temporary solutions, etc. Instead the impression is that you're just washing your hands of any responsibility to your customers because it's not 'your problem'.
