Samsung Messages app: some people not receiving text

Some of my recipients don't receive any of the messages I send. How can I fix that?

Might have something to do with the impending discontinuation of Samsung Messages. They won't be supporting it. Users will need to migrate to Google Messages.

It's not being discontinued... they are only pushing folks to Google Messages for a more enriched RCS experience. I'm using Samsung Messages with full RCS/Chat Settings on my Flip6 (AT&T). Stop telling people it's being discontinued when it is not.

It's from your carrier. It's a hit and miss that always happens. Texting is not reliable on any app
