Made this account just for figuring it out since theres nothing for my particular model out there that isnt the basics, nor nothing in here ( closest on the mms issue is for later entries to the galaxy series)

I have a galaxy note 9 , on the super lte network and ive had a issue recently with getting mms messages , they always end up on download and later expire since I cant get to them, or sending a mms since it doesnt send at all . Tried messaging the site for help to no avail (were p helpful however, just wasnt helping the issue) is there something im missing ? It worked perfectly fine before and it should work perfectly fine in my area when i checked the coverage map

​

(As a side note if anyone has advice on what to do/how to set it up so this wont happen to the note 10 since im planning to upgrade to at some point it would be a big help as well, thank you!)
