My S24 Ultra has a horrible time sending MMS. Group texts and photo/video messages never go through. I have to send 3+ at the same time for the last one to go through. Then the rest spin continuously. Verizon is no help except they do something when I call and everything works and then a day or hours later...back to not working. Clearly they know something and are no help. Seems odd to have a $1,300 phone that won't work on their network.
