Hello all, just got the 17 Pro Max and 5G standalone is disabled. Says my SIM card does not support it. I’m on AT&T. Anyone else having this issue? I called AT&T and they said they couldn’t do anything about it on their end. What?!
 
It's been blanked out for me for as long as I can remember.

Couple of things.

I think ATT really has not rolled out true 5G in many places. Per their website, it's only in arenas, busy areas. So really can't limit ATT to SA mode only.

Right now, high-band 5G+ with lightning-fast speeds is available in select airports, stadiums and venues, and other areas where people gather, like entertainment districts. Go to att.com/5Gforyouto read more about the latest details and locations for our high-band 5G+.

Our mid-band 5G+ experience is in limited parts of select metro areas. Our network team is working hard to continue to expand across the U.S. Learn more about AT&T 5G+

And, unfortunately, it's nothing Apple can do. Not iOS related. The Standalone option is carrier controlled. Will need to deal with ATT.


Additional settings such as 5G Standalone and Voice Over 5G Standalone may be available in your market. For more information, contact your network provider.

Im on an older unlimited plan…I wondered if that was the cause? Maybe standalone is tied to certain plans?

Also, my wife’s 16 Pro and my iPad Pro both have the toggle on.
 
You'll have to ask ATT.

The option is controlled by the carrier settings file. Controls features that the carrier will support on a device. Each carrier has their own configuration files. No master file for this.

Usually gets updated during an OS update but will sometime see a message about updating carrier settings on the device.

No matter what, could be almost anything other than an iOS issue.

For sure. I have escalated to Advanced Tech Support twice and the two reps I have gotten have given conflicting information.
 
Upgraded from 14 pro max to 17 pro max; had 5g standalone ON on my 14 pro max, but after upgrading to 17 pro max, that option is now greyed out. I’m on At&t as well, same plan.
