No, Apple cannot fix a problem with your phone that doesn’t affect hundreds of millions of other iPhones with a patch. The only chance for Apple to fix it is to troubleshoot it either yourself or with Apple’s help.

Have you tried updating your carrier’s settings→Update your carrier settings on your iPhone or iPad - Apple Support

Best way to contact Apple: 

• Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) access to diagnostic data on your device

Other options:

• • Click on “Support” at the top or bottom of this page
  • Go to Contact Official Apple Support

(Note that both of the above have options to receive a callback or chat)

• • Call Apple Support; the phone numbers are in this link→Contact Apple for support and service - Apple Support
  • Make a Genius Bar appointment at an Apple Store→Genius Bar Reservation and Apple Support Options - Apple
  • Find an Apple store or Apple partner service provider→Find Locations

Check cellular/Mobile settings for an update.

I think that is Settings/General/About for carrier updates→Manually update your carrier settings on your iPhone or iPad - Apple Support

You are correct, much obliged.

I have a similar problem. However, when I try to use only one SIM, the signal is better, but still not as normal as it was before I updated to iOS 18.5. My workaround is to close the dual SIM function and only use one SIM for now. Hope Apple can fix this issue in the next patch...I am using my backup phone for the second sim now..

I tried to update the cellular settings and reset the network settings, as well as perform a hard reset, but it didn't help.

Restart the phone.

If you have a physical SIM, remove it and put it back while the phone is still powered up.
