I've found an answer for a similar question, but it does not apply to iOS 26. I'm trying to send someone a photo, I'm getting an alert saying I have to enable MMS in order to do so, and I cannot find anything in Settings -> Messages that says anything about MMS. What's the secret?
iPhone 17 Pro Max
Well it turns out I was jumping the gun in my case – when I posted that message I didn't actually have cell service – I'd just gotten a new iPhone 17 Pro Max and my carrier was having technical difficulties switching me over to the new phone – and now that my cell service has been restored I see the options for RCS and MMS and other things.
I suppose if your cell service is fully functional and you're not seeing those options it could be as the other poster said and you need to get in touch with your cell carrier.
Thank you everyone for your help!

I also had this issue but I was able to resolve it by doing the following
Not sure which combo of these did the trick, but I can now see MMS messaging on my iPhone 13 pro updated to ios 26
The option for MMS randomly disappears for me with the new iOS. I also have full unlimited everything through my carrier. If I reset my phone, MMS option will work again and reappear.

If you scroll down enough in Settings > Apps > Messages, there should be a toggle for 'MMS Messaging'. It's in the section labeled 'Text Messaging', under the menu for RCS Messaging.

Interesting- it looks like this:
If it's not in the list, you likely don't have MMS with your cellular plan. In that case, you'd have to talk to your carrier.
Yeah, it may be good to contact your carrier then. Maybe they've failed to update something that needs updating because of iOS 26...or something. Good luck!

How do I enable MMS in Messages in iOS 26.0.1?
