Why can't I send/receive MMS text messages on my Samsung Galaxy S6 after Marshmallow update?

FYI: I'm using stock text messaging and my carrier is Straight Talk.

I'm also only partially "phone smart" where these things are concerned. Not totally dumb about it, but sometimes you guys (and gals) are WAY over my head.

Mmmm, perhaps your settings slipped a little after update. Call your service provider on another phone and go through your settings with them.
Generally is a good idea to wipe cache partition after bigger updates to clean the device out a bit..
