Who I have the same questioned this topic

I just got a new Samsung Z Fold on Tues. It is now Friday and I still cannot receive any MMS or send any MMS. It just says that they failed to send or just indefinitely attempts to load one that was sent to me without success. I have tried Samsung messages, Verizon messages and Google messages. I have tried just using WiFi, just using data, and having both WiFi and data on. I've gone through numerous threads and have tried everything I can think of and it still won't work.

I've restarted my phone multiple times. 

I'm at a loss. Please help.
