iPhone 13 Pro Max won't connect to cellular after iOS 17.4.1 update

Agreed its not always the IOS, but mine has essentially become unusable on the Cellular Network.. I reboot, it connects to 5G for a few minutes, down grades to LTE ... then drops the network ...

Additionally, its driving a reboot of the phone (two year old phone) starting this past weekend. Nothing else on the phone has really changed...

It appears there's some kind of software failing here ...

(iphone13, ios17.4.1)

Having this issue now. One thing I noticed is I can unable to update the network settings successfully.

Settings>General>About wait for the pop-up, click “Update”. Then nothing happens.

iPhone 13 mini

eSIM-Mint Mobile

iOS 17.4.1

xactly same issue on my Iphone 13 Pro Max.

Run Diagnostics & Repair , Enhanced logging.

Multiple full reset

Store visit for a full hardware and software ( Mobile resource inspector scan). All checked out green.

New SIM from ATT.

Nothing solved the problem.

Finally today spend 2.5 hours with Service Advisor to get an acknowledgment that it is an known issue and they don't have a resolution yet as they are still investigating the cause.

Hopefully Apple can fix this for us. I cannot just be ask to buy new iphone for their buggy IOS 17.4.1 updates

Thank you so much for your findings Dr. Fauci.

Just went to the Apple Store and got told absolutely nothing can done and have to wait until apple issue an update witch is unacceptable considering my phone is a paperweight at the moment

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:

Apple themselves have confirmed that this is a known issue with something related to IOS. it is not hardware or carrier related.

I have this EXACT same issue. My husband spent all weekend trying to get his phone connected to ATT service. Apple is sending him a phone to arrive in 3-5 days. ATT says they can't help at all! This ruined my Mother's Day. We have been back and forth from ATT and Apple all weekend long. Have you not had any issues with your new phone? Luckily, my husband's phone was still under warranty because Apple said there is nothing wrong with it when they ran the diagnostics. ATT's solution was to "wait it out." Also, they wanted to send us an old Android! I see you posted over a month ago...thanks ATT for the wait it out solution.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.
