Cannot Send Message: MMS Messaging needs to be enabled to send this message

So I had an IPhone 11 for multiple years and then last year it stopped working with group messaging or sending gifs/pictures/video messages unless they were through iMessage.

The only thing that I can think of that caused this was that I got an eSim while traveling abroad around that same time. When I returned, I removed the eSim and continued with my Verizon plan, and that is when the MMS messaging error bagan.

I did a lot of troubleshooting, through every post I could find about MMS Messaging and group messaging. I called Verizon and they said that MMS was enabled on my plan.

I tried everything, so I finally gave up and decided to switch carriers to T-Mobile. I now have an iPhone 14 Pro with a T-Mobile Unlimited plan with MMS/Group messaging activated….. and it still is not letting me send messages.

I am wondering if this is because I set my new phone up using an iCloud back up for the iPhone 11. I don’t know when the issue began with my messaging, but at it was at some point in September of 2022.

I just don’t even know what to do anymore.

Went through the same issues. Tried all the usual tactics, including resetting network settings and confirming services with carrier. But I didn't want to reset all settings or wipe my phone. Too much of a hassle. But I figured out a solution.

Context: I had enabled a Flexiroam eSim for travelling purposes a while back. Wasn't using it, so I turned it off in Settings>>Cellular. Note that I did not actually delete/remove the secondary eSim. I only deactivated it. Ever since then, SMS messages to non-iPhone users have been acting wonky... lots of errors in sending and duplicates received by the recipient. And I recently realized that MMS messages weren't working. Got the "Unable to send" error. But "MMS Messaging" appeared enabled in Messages settings.

So... I re-activated my Secondary eSim. Now, all of a sudden, the MMS Messaging toggle appeared as "off" (despite it being on prior to this action). So I toggled it on. And all of a sudden, my MMS Messaging works perfectly.

I even again de-activated my Secondary eSim after the step above and confirm that MMS Messaging is still working. Yay!

Hope this helps others.
