Why does iOS block downloading Enhanced Accessibility Voices over 5G?

Question

Why does iOS block downloading Enhanced Accessibility Voices over 5G?

Has anyone else run into this frustrating issue? I am trying to download the Enhanced Slovenian voice (Tina) for text-to-speech. The file is only 84 MB, and I am on a blazing-fast 5G connection pulling over 300 Mbps.

However, the download just spins endlessly in the Accessibility settings. I finally realized iOS hard-blocks these voice downloads over cellular data and forces you to find a Wi-Fi network to complete it. Why are we still dealing with 3G-era download restrictions on modern devices? Is there any hidden workaround to force iOS to trust my 5G data?

iPhone 14, iOS 26

I am glad it worked on your setup, but this issue is specifically about background asset queued downloads failing or hanging on cellular for larger or non-US voice packages like Tina Enhanced and Jamie Premium.

Even with 'Allow More Data on 5G' enabled, the iOS asset downloader frequently stalls on cellular data due to carrier profile restrictions and background queue policies. The exact same download triggers instantly the moment a Wi-Fi connection is established, which points directly to an iOS cellular download restriction for these specific voice assets.

Nope, iOS isn’t blocking it.

I just downloaded the Allison enhanced voice on cellular.

I suggest you check your settings to see why it’s not working for you.

That's great, but what settings should we check?

I'm trying to download Jamie Premium (137MB) on a super-fast 5G connection and it's been stuck for hours. I have 100GB free space on my phone. I remember something similar happening with the clean-up tool in the photos app. I think I had to use wifi to download it, but I'm nowhere near wifi today.
