Why is my iPhone showing no signal after iOS 18 update?
After updating my iPhone to iOS 18, I started experiencing a frustrating issue where my phone consistently shows ‘No Signal’. It was working perfectly fine before the update, but now I can’t seem to connect to my cellular network at all. I’ve tried restarting my phone multiple times, but the problem persists. This signal issue is causing a lot of inconvenience as I rely heavily on my phone for both personal and work-related communication. I’ve also noticed that other devices in my area are not experiencing the same problem, which makes me think it might be specifically related to the iOS 18 update. Can anyone explain what might be causing this and why my iPhone can’t connect to the network after updating?

If none of the usual fixes worked, the problem might be related to the phone’s hardware. This happened to a friend of mine after a previous iOS update. They had to:
1. Visit an Apple Store or an authorized service provider.
2. Get the phone checked by a technician.
3. The technician found that the antenna needed adjustment.
If your phone is under warranty, this is usually a straightforward process without much hassle. Identifying this as a potential hardware issue might be the key if software fixes don’t work.
Dealt with this issue myself and it was quite frustrating. Sometimes, updating your carrier settings can solve the signal problem. Here’s what I did:
1. Connected my phone to Wi-Fi.
2. Went to Settings and tapped General.
3. Selected About.
If there’s an update available for your carrier settings, a prompt will show up. I updated these settings, and my network was back up and running.
I faced this issue as well and guess what worked for me? Turning the Cellular service off and on. It sounds simple, but sometimes it does the trick:
1. Navigate to Settings.
2. Tap Cellular.
3. Turn off Cellular Data.
4. Wait for a few moments and turn it back on.
This quick action rebooted my network connection and resolved the ‘No Signal’ issue.
My experience was a bit different; the issue was with the SIM card itself. After the iOS 18 update, my phone didn’t recognize the SIM card correctly. Here’s the process I followed to fix it:
1. Turned off the iPhone.
2. Removed the SIM card using a SIM ejector tool.
3. Cleaned the SIM card gently.
4. Reinserted the SIM card carefully.
5. Turned the iPhone back on.
After this, the ‘No Signal’ issue was resolved, and my phone connected to the network without any problems. It seems that removing and reinserting the SIM card helps the phone detect it properly.
I had a similar problem with my iPhone after the iOS 18 update, and the solution turned out to be resetting my network settings. Here’s the step-by-step process I followed:
1. Open Settings.
2. Tap on General.
3. Scroll down and select Reset.
4. Tap on Reset Network Settings.
After following these steps, my iPhone rebooted and the ‘No Signal’ issue was resolved immediately. It seems that the network configurations were disrupted during the update.
In another instance I had, I reached out to Apple Support. Sometimes, these signal issues are due to software bugs related to the new update. Here’s what I did:
1. Used the Apple Support app to contact them.
2. Detailed the problem and mentioned all the steps I had already tried.
3. They guided me through additional troubleshooting steps.
4. Apple identified it as a bug and released a software patch a few days later which resolved the issue.
Reporting the problem to Apple helps them address software bugs and provide fixes quickly.
