I have a Galaxy S9 Plus. Normally I use the stock messaging app or Textra. For the past couple of months I've been using Textra no problem over Wi-Fi. Since I have Wi-Fi calling enabled SMS and MMS are sent over my Wi-Fi networks as I only have 1x signal in my house. I had the S8 plus before this and I've been using it for over a year.
The past few weeks for some reason text works fine but I cannot send MMS over Wi-Fi. I can receive them just not send them. I actually did a factory reset on my phone and it didn't help so I did a factory reset on my router and it helped for about an hour. I've already talked to Verizon and AT&T who is my DSL provider and no one can figure it out. I've temporarily switch to the Verizon messaging app but I'm having other issues with it although the MMS is working. I would rather use Textra or the stock Samsung app.
Here's a short video of it working on public Wi-Fi. I've also verified that if I make my home network unsecured that it works fine. Once I re-enable the security and password MMS stops working again.
