5g not working since iOS 16.4 upgrade

My 5G is not working after I updated 17.5.1 iOS

Agreed l! I’m using iphone 12 and before update of 16 (major update) i was able to switch over 4g to 5g and even there was option to run 5g as standalone.

after updating 16 and .1, still not able to switch 4g to 5g.

I think you are incorrect. I am having the same problem with iOS 16.4/16.4.1 I even changed from eSIM to Physical SIM. The network is good enough. I cannot see 5G standalone toggle though. It's Apple problem. The same issue is happening with both my SIMs. All over the city.

Let's see, millions of people with the same phone and the same carrier running the same version of iOS are not experiencing the problem.

That puts it squarely in the carrier's camp and some type of issue with your local tower and towers and/or your account.

If you believe it's the software, feel free to lodge a complaint with Apple here:

Meanwhile I will be here giving the same advice, as most people who have had this issue resolved have done so after working through it with their cellular carrier.

I'm glad a hard reset worked for you.

Have you installed the latest carrier settigns update?

1. Make sure that your device is connected to Wi-Fi or a cellular network.
2. Tap Settings > General > About.
3. Follow the onscreen instructions to install your carrier update.

I tried everything nothing works. In the voice & data options before there was showing standalone option and now it is not showing after updating to ios 16.4.1

please show how to solve it if there is any solution

If your carrier account is not setup to offer 5G service that option may not appear even grayed out.

Do you still see the other 5G options?

For example, if I set the Voice & Data option to “LTE,” the greyed-out “5G Standalone” option also disappears.

I am not able to access to the 5G after I upgrade my phone in 16.4.1. This issue as occurred recently and and the indicator is stuck as LTE and not showing any 5G. I have already contacted my service provider, and they have done the troubleshooting and the issue is only about the updated version of iOS.

Another iPhone of the exact same model?

If so, you may want to have your phone examined.

If not, you can't directly compare say, an iPhone 13 against an iPhone 12 with the same SIM card; the capabilities of the devices are different, and that's where carrier configuration of your local cell tower comes into play.

First, make sure your device is fully updated, the most recent version of iOS at present is 16.5.1:

Second, if you believe it's your device, contact Apple Support directly:

Most iPhone 14 owners are seeing more 5G signals than ever.

I don't know which carriers you have, but often many carriers share the same network so multiple carriers may in fact be the same from a signal point of view.

If it were great on their end, you wouldn't be experiencing the issue; if it were an issue with iOS 16.4, we'd see a huge number of posts from people experiencing the same issue.

Have you tried traveling several miles away to determine whether you see 5G from other cell towers?

Your service provider is incorrect.

There are literally millions of users with the same device running the same version of iOS using 5G without issue on their network.

As I asked another user above, have you tried traveling several miles away to determine whether you see 5G from other cell towers?

iOS 16 allows you to shut off 5G under "Cellular Data Options," but that is all.

If you cannot connect to 5G networks it is a configuration issue with your account in your cellular provider's system or a tower issue.

If it's on multiple towers we are back to an account issue.

If you have a physical SIM, make sure it is one that supports 5G service, not all do.

Simply put, if it were iOS, it would be broken for everyone.

When you do that, it causes the cellular network to resync with the capabilities of your phone.

That's why when you go from a cellular plan without 5G to one with, carriers tell you to do the same - shut off your phone, wait several seconds, then turn it back on.

Carrier Settings are definitely used in India (and everywhere else) - they don't lock your iPhone to a carrier, rather they are what allow your phone to be used with a carrier - they're essentially a preferences file for the network of the carrier you are currently using.
