iOS 17.0.3 breaks 5G?

[Prof.]

Is anyone else experiencing this? I live within eye site of a Verizon 5G/UW tower and since 17.0.3 I no longer get 5G coverage at home, and very little 5G coverage when driving. Also, I'm lucky if I get 1-2 bars of LTE at times in my home. I've reset network settings, turned off/on the eSIM... nothing works.

I have noticed on my iPhone 15 Pro Max, on T-Mobile’s towers, that the cellular signal (bars shown at the top) is far lower by 1-2 bars compared to before 17.0.3 (on 17.0.2) or when my iPhone 12 Pro Max was on 17.0.2 before I traded in. To note, my T-Mobile 5G capable cell tower is about 700ft or so away so I normally have all full signal bar strength.

My speed is just as good, so appears to be a visible change vs. a backend change that has slowed the speeds down at all.

I can barely load webpages, or place a mobile order for coffee. Hopefully this is fixed with iOS 17.1 or 17.0.4.

Haven't noticed any difference but now I'll pay attention to see

Seems fine to me with my 15 Pro Max and AT&T

5G is still working for me with a 2022 SE and 17.0.3. I'm not in the US.

iPhone 13 here.

Since iOS 17.0.3, my cellular data randomly stops working sometimes. I have to toggle airplane mode on and off to restore it.

I can't confirm if it's an issue in my area or an iOS issue...I suspect it's iOS as it was mostly fine before (although the Three UK network can be dodgy at times).

As the OP has done, I've also tried resetting network settings. I seem to remember this was an issue in the early days of iOS 16, too.

Same happening to me on Verizon. Used to get 5G UW in more areas, now seeing LTE a lot more. Definitely getting less bars than on my old iPhone 12 Pro Max

Not sure what happened, but at least for sub-6G 5G networks, it seems to work fine with (17.1b3, 15PM, China).

If you don't mind, I recommend loading 17.1b3 to see if the issues are resolved. Perform an iTunes backup first before hopping on the beta train, just in case of any regrets.
