I have a friend that uses Android, her and I text cat pictures to each other all day. But today I started getting an error while trying to send any to her. I can send messages without images fine.
I looked in message settings for an option to enable MMS but do not see anything. I searched settings as well.

I get this when I search, but touching it brings me to messages settings and no mms options.


That is strange, RCS should be able to transfer images.
It had been working fine for the last 2 1/2 years that I had this phone. Never had to change those settings once the initial setup was complete. Started receiving the error out of the blue. I reset all of my mobile network settings and it started to work again.
