Reset Network Settings: Only network settings are removed.

• When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
• To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
• To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
• Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

If the above fails...

Reset All Settings: All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.

1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
2. You can return settings to their defaults without erasing your content.
3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.

If nothing above works probably it could be your iPhone may have a radio or antenna problem. In that case, take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support and get the hardware tested and if needed repaired/replaced.

I had the same exact issue. iOS 16.6 fried the whole entire hardware system. They had to replace my phone. There is no fix for this if the SIM card isn’t reading and if the other things don’t work.

I'm having the same issue. I have a 2nd gen SE. My phone was scheduled for the 16.6 update. When I woke up the next morning, my phone read SOS only where my carrier info is usually located and flashing in the middle of my screen is No SIM Available. I took my phone to my carrier 3 times. They adjusted the SIM and ended up replacing the SIM. Nothing changed. I spoke with my local Apple store. They reset my phone and ran diagnostics. They told me the RF signal from the phone to the towers wasn't communicating properly. They told me they only fix is to replace my phone which was almost $400. My phone worked just fine before the update...no water damage, no drop damage, no damage of any kind. I was very disappointed with Apple. I never liked Apple products until I started selling them at a cell phone carrier. In order to properly do my job, I had to be able to work with and set up Apple phones. The easiest way to learn was to own one. Since then I've come to love iPhones at least. This is my second one and I'm ready to upgrade but my finances aren't ready yet. Due to Apple's 16.6 update and the lack of quality customer service I had anticipated, I'm forced to buy a new phone when I can't afford one because Apple's update destroyed my phone and many other people's too. Apple needs to repair or replace these devices because Androids are cheaper and now have a lot of the same features. This isn't Apple quality and I just don't get why they aren't acknowledging their mistake and fixing it yet. My phone has been down for 3 weeks now. That's money wasted on this months service, a new phone I can't afford and the gas and time I wasted thinking someone was gonna get my phone fixed.

Updating iOS on your iPhone should typically not alter the fundamental functionality of the device. In general, iOS updates are designed to enhance the user experience, improve security, and fix bugs, rather than introducing major disruptions to core features. The reported issue of the screen flickering and displaying a white screen after an update is likely caused by factors that are not explicitly mentioned in your post.

iOS updates primarily focus on improving system performance, introducing new features, fixing bugs, and enhancing security. They are designed to preserve your personal data, settings, and information intact.

During an iOS update, your device's operating system is upgraded, but your personal data, such as contacts, photos, messages, and other information, should remain unchanged. However, it's always a good practice to perform a backup of your device before any major update to ensure that your data is safely stored.

It's important to note that while an iOS update itself should not alter personal details, it's possible that certain features or settings may be adjusted or improved with the update. In such cases, you may need to review and adjust specific settings to match your preferences after the update.

Always make sure to read and understand the update details provided by Apple before proceeding with an iOS update, and follow best practices such as backing up your device to minimize any potential risks or complications.

If the issues you mentioned are indeed caused by iOS, it's likely that numerous users who have upgraded to iOS 16.6 are experiencing similar problems. However, in order for the community on this forum to provide helpful responses, it would be beneficial for you to specify the nature of the issue you are encountering. Without this information, it may be difficult for others to address your concern effectively.

With the limited information that you have provided, It is hard to even guess the problems faced by you.

Please re-post with detail so that someone else can help.

Same issue.. updates to ios16.6 and lost cellular funtionality. Settings to add cellular; e-sim settings; etc all gone. Can not manually enter details to add, doesnt give option to scan QR code, etc. Have not tried to re-install 16.6 for the sheer fact Id prefer not to reset my phone but sounds like thats the fix. Ugh!

Hi, after updating 16.6.1, no wifi, and strangely, no data cellular, voice working!!! I tried everything, and I had to make a hard reset, and it work, and a few minutes later, crash again. Wifi didn't work, and data didn't, worked. But then, after som tears, I tried to take a Genius Bar appointment, and it worked, wifi and data cellular. It is 8pm, still working! I hope for the iOS 17, to clear everything, and start fresh again. It is appalling to see apple do update and didn't check for does MAJOR bug for certain of us. I have a iPhone 12 Pro Max, and I hope, tomorrow morning it is working. I had to configure everything (3 hours)! Crossing fingers! My phone is the only phone for the house, so I hope I don't have to send it for repair, for 10 days!

Exact same thing here! I have an 11 Pro. It happened the other night after the 16.6 update. I tried everything with my carrier and with Apple support including multiple SIMS, physical and electronic, and ultimately a factory reset. Nothing. Conveniently the 15 is being released this week. Coincidence? I think not. This is the first problem I’ve ever had with an iPhone in the 15 years of having one. Inconvenient timing as I’m in nursing school and not working a lot so I really can’t afford a new one, but I have no choice. I haven’t decided if I’ll continue with another iPhone or not. It’s too big of a screw-up for me to not consider other options where in the past I never would have considered anything else.

I’d call apple again, and tell them this happened during the update, your phone forced it and that now your phone is worthless

I don't understand why Apple gives updates when the updates affect cellular connectivity. Now it's Saturday evening and I have this problem on my iPhone 13 after updating to iOS 16.6.1, I can't connect Apple support or network provider until Monday morning. I was wrong to trust Apple.

Mine is a sim issue so I’m not sure it’ll work. And I’ve already updated to 17 thinking maybe it would resolve itself, but it didn’t. Did a factory reset after, too. Garbage update at the worst timing possible. I expected more from Apple.

So every support person on here is absolute garbage you know this issues is still persistent and continue to give the response “go into a store to get it repaired”. But you as the person with the phone can just redownload the update on your computer and reinstall the update but youll have to do it every update as apple is just a huge scam

Apple support will not help you, they will just tell you some bogus “fixes” when they know of the issues and will prompt you to get a “repair” which will be ungodly expensive as they are a scamming company

@dubs thank you very much for posting your solution. Your fix worked for me too. Much appreciated!!!
