Cellular network off after 17.4.1 update

Do you also have an iPhone 14 Plus???

Upvote if yes. Downvote if no, but you have same issue

Sorry to break it to you buddy, it’s IOS side of things, thousands of people are having this same problem after the update on relatively new IPhones

the iso update is surely the issue. Didn’t have any issues until my phone updated overnight. Went to my carrier, and they believe it is the iOS update. They tried a new e-sim, reset my network settings, amongst other things.

I work in software development and while things are tested thoroughly before deploying the changes, issues do sometimes still happen. No one is perfect and with the number of people having issues, I believe apple messed up the iOS update.

FIX: Anyone who has encountered this issue. Make sure your phone is backed up and you’re going to have to factory reset the phone to be able to use cellular data again. This has worked for multiple people.

All this information is great. However, how do we fix it. My iPhone updated overnight and now my cellular is down. Zero “bars”. My number is turned on in the phone. Will not allow me to use my phone number for iMessages either. How do we fix it ?!

I am also having this same issue after updating to 17.4.1. I am on ATT and now am unable to connect to the cellular network. This is definitely an issue with the software update. I have an iPhone 13 Pro.

I was told from apple support that the software update was causing the issue. The only solution given was to wait for a new update as they were working on it due to multiple people reporting the same issue internationally.

I have an iphone 14 plus. My phone would not connect to the verizon cellular network immediately after 17.4.1. Would not update carrier settings (would click the popup but nothing would happen.) Tried everything except factory reset, without avail.

Things were like this for 48 hours until I gave up and factory reset the phone, and it immediately restored connectivity. If you are desperate, try this. I did a reset while maintaining my e-sim card and it worked, so I didn't have to drive to the verizon store.

Good luck everyone, what a pain in the ***!

Apple support will not be helpful, but if you want to fix this without a headache just backup your phone and do a factory reset because nothing else will do the trick.

Sadly this situation may be the IOS update fault.

hundreds of people are having the same issue, and unfortunately it is all pointing towards the IOS. Telling people it’s not that can also make it harder for them

to seek resolution- as if they are like me and having this issue - cannot find any resolution.

some of us don’t have access to a backup and some updated overnight without expecting any issues

It surely is not iOS 17.4.1 because...

I conducted a thorough search of this forum using the term 'Cellular network after iOS' and uncovered numerous posts detailing similar issues across various iOS updates. This suggests that iOS updates may not consistently be the root cause. Below are a handful of examples extracted from over 6,000 search results:

Hi,

Apologies, without an older back-up this doesn't help, but for others like me who were desperately looking for a possible fix. Updated my 13 Mini to IOS 17.4.1 overnight and lost all connection to my mobile network. Came to these forums to see that I am not alone. Was only able to access internet, social media, and send messages via Wi-Fi.

This, touch wood, is working for me:

• Save a back-up of your phone as it currently is, with IOS 17.4.1, even with its bugs.
• Restore your iPhone to a back-up that pre-dates that IOS update.
• Let that happen, re-set up your phone according to the prompts, get it running (this was how I confirmed that it is the update that is the problem, not the provider, as my mobile network was totally fine and operating again on the older IOS)
• Restore from a back-up again, but this time restore the back up that is with IOS 17.4.1

For me (here in Australia) this has allowed me back onto my network (4G at least - a return to 5G is a wait and see).

A caveat is that I'm restoring from back-ups on an iMac, not from the cloud. That may make no difference, but FYI.

Hope this helps a few people.

Gobsmacked that Apple must be aware of this but not acknowledging. Maybe they're frantically trying to fix!
