I have an S10e on Xfinity mobile with the stock messaging app, it won't send MMS messages at all anytime WiFi is turned on. Even if mobile data is still on, it won't send. From everything I've read this is a known issue and effects everything from the S8 up since OneUI and Pie were rolled out. If this a carrier issue, a Samsung issue, or what? Everyone is passing the blame and nothing says how to fix it. Please help!

I tried all the solutions on here yet none seemed to work. Switched to the unmetered on my WiFi, etc. If I disconnect my WiFi on my phone, the text messages will come through. But, it's a pain to keep doing that.
I called Samsung and they told me to clear my cache, same as the originaly solution. I did that already! But, I only did that on my one messaging app. What they meant was to clear the entire cache by going into the developer mode on the phone. To access that, you need to turn off the phone and then hold the power button + the up volume button. Use the volume keys to scroll and the power button to select to clear the cache. It takes a second. Then reboot the phone.
I did this recently and so far it's working well. Fingers crossed it actually fixed the problem!
I will add my $0.02. I have an S10 Plus on AT&T Prepaid. I purchased the phone while on vacation. It worked great in NY and all the way to FL. After returning home to SE Alaska, it all changed. My prior phone worked great off our home WiFi. This one, not at all. I cannot make or receive telephone calls that can be understood and cannot send pictures via text or email at all when connected to WiFi.
I have tried both WiFi calling on and off. I have checked for data saving settings. I have gone in and cleared the cache. I have reset the network settings. I have done everything suggested above to no avail In as much as we are in a poor area for AT&T reception, we cannot use the phone without a booster. I am working on that. In the mean time I need it to work on WiFi and I am very disappointed.
