One person’s opinion on a specific technology is really problematic (and I value slava’s opinion very much, what can be a dying technology in one geographic region and seem like dying can still be thriving and growing elsewhere, see mms usage in US vs europe etc)
Edit: just to prove a point not a single carrier dropped mms in europe where it was ‘dying’ in almost a year, when we get information about killing mms like 3g we can re-review, as far as I can tell mms is here to stay for a while longer
Edit2: afaict it’s actually growing with now audio mms becoming norm for ppl to record a message etc, haven’t seen that before, whether mms now being free and not premium or androids finally incorporating it more easily for ppl to use, my own experience is totally contradictory to the ‘dying’ statements, ymmv
Most “ MMS” used now are actually RCS messages. The switch is totally invisible for most users using either Google Messages on Android or iMessages on iOS.
Well it’s visible for me 100% sure not using rcs and started to get a ton of audio mms which never happened <2025, so whatever it is it’s actually growing, so claiming mms is dying is for me foolish (and if it’s technically rcs on their side, who cares, still ends up being mms on mine)
Edit: or alternatively: YAY we got rcs support guise!
Maybe people are just sending you regular voice messages like most people do through rcs/iMessage from their android/iphones, but you are receiving them as an MMS because you don’t have rcs/iMessage.
That’s what makes sense at least, because “voice MMS” is not a thing. Just a fallback mechanism like send as sms if rcs/iMessage is not available.
Vodafone Germany dropped MMS January 17th 2023.
Here in Germany, for example:
Vodafone: “The service was discontinued on January 17, 2023, to modernize the network and save energy.”
Telekom: “Sending and receiving MMS messages on our mobile network will only be possible until June 30, 2026. After that, the MMS service will no longer be available.
And Switzerland and the Netherlands have discontinued MMS, too.
You do realize Graphene OS exists, right?
Another pointless comment about an android custom rom that runs on Google hardware. Totally relatable to sfos and j2. Somehow.
If I had 1€ for every user that is so happy with that rom but always lurks here I would have enough to get J2 for free.
Even if somehow i loved Android, I found the guy in change of that project completely mentally stable, and I would be very happy giving my money to Google to get their phone, just the user base alone would be more than enough to drive me away. So I guess good job in a way?
Ah sorry, I’m sometimes forgetting that they’re an Android fork and not a proper OS in their own right.
Even if a bit toxic at times.
I think it is very ridiculous: a Google Pixel phone that offers privacy? Ah, we are already trying to stay away from big giant companies like Google. 
No, multimedia messages were a thing even in 200x, some nokia phones could send and receive up to 40sec of video, audio, images etc, audio mms definitely is (was?) a thing, even wikipedia covers this and ways isps transcribe multimedia messages to different codecs (mmsc):
Unlike text-only SMS, MMS can deliver a variety of media, including up to forty seconds of video, one image, a slideshow[2] of multiple images, or audio.
Before delivering content, some MMSCs also include a conversion service that will attempt to modify the multimedia content into a format suitable for the receiver. This is known as “content adaptation”.
Interesting, what happens when you send an mms to a vodaphone user? Does it bounce with: their isp is unable to process? Just errors out? Or does it forward it to rcs(google) and nothing happens?
I know, that’s what I’m saying.
25 years later the most common reason to receive a voice message as MMS is someone sending you a typical voice message from iPhone/android, but ends up like MMS as fallback because you don’t have iMessage/rcs.
In some countries they were included in contracts, while in others they’re still pricey.
I have these off as an example.
Well just from your picture you can disable rcs, enable mms and will be free from googol spying on mms (about pricey, no idea, all isps in my country offer unlimited sms/mms as base package nowadays, probably because of all the rcs->mms fallbacks)
Works a treat here in Australia via Voda
MMS is still popular here
You will receive a SMS message with a URL pointing to the content of the MMS. I have this experience once a year on my birthday. 
Vodafone Germany
Until other carriers follow the trend and remove MMS from their offers.
