To the OP and ALL those Affected:

This seems to be catching on. So,...

Report this to Apple:

Do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

1. Go Here: Feedback - iPhone - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment: that this all began after installing an update. Include the URL of this thread.
4. Proceed from there as necessary

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!

Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

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.

Excellent job troubleshooting!

Thanks for doing your part! It will help many, for certain!

have you fix it?

Please tell me about it , having the same issue i have updated my iphone16 since then no cellular network at all. I don’t know what to do, please help

The cellular signal strength on an iPhone is primarily dependent on the service provider and the network coverage they offer based on the plan you have selected. Different carriers have varying levels of coverage in different geographical areas, and the strength of your signal can fluctuate depending on your proximity to cell towers, obstacles like buildings or natural terrain, and overall network congestion.

It’s important to understand that there are no software settings on your iPhone that can directly boost cellular signal strength. However, if you are consistently experiencing a poor signal despite being in an area with generally good coverage, it’s worth checking a few things. First, ensure your iPhone’s software is up to date, as carrier settings updates can sometimes improve connectivity. You can also try toggling Airplane Mode on and off, which forces the device to reconnect to the network and may establish a stronger signal.

A few carriers (Cellular Service Providers) do not provide Carrier Settings in full, but they offer APN settings, for example

• Google FI, which has APN to be entered manually as h2g2
• MTN Ghana, which provides an APN pin to be updated manually, as the internet
• BSNL in India, which provides APN pin to be updated manually as bsnlnet (Watch the GIF below)

Settings > Mobile Data > APN [under Mobile Data APN] enter the APN pin

View and edit your APN settings

If your carrier allows it, you can view your APN settings in one of the following locations: Settings > Cellular > Cellular Data Options > Cellular Network. Settings> Mobile Data > Mobile Data Options > Mobile Data Network.

View and edit your Access Point Name (APN) on your iPhone ...

Use the APN pin based on your carrier. Ask them (Your Carrier) or search using any search engine.

If these steps don’t help and the problem persists, there’s a possibility that the internal radio antenna of your iPhone may be damaged. This can happen if the device has been dropped or exposed to physical stress. In such cases, having your iPhone inspected and repaired by an authorized service provider is the only solution that could restore proper signal strength. A damaged antenna can significantly impair your ability to connect to cellular networks, leading to dropped calls, slow data speeds, and limited coverage.

If you have either dropped the device accidentally or exposed it to liquid or used it beyond acceptable temperature limits then…

Take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support:

Find Locations - Location Selector - Apple

Contact Apple for support and service - Apple Support 

Get a Genius Bar Reservation and Apple Support Options - Apple

Contact Genius Bar.

Manage Reservations - My Reservations - Apple

In summary, while the quality of your cellular signal is largely out of your iPhone’s control and relies on your carrier’s network infrastructure, keeping your device in good physical condition and ensuring software updates are installed can help mitigate connectivity issues.
