Fifth solution: Remove then reinsert the SIM card on your iPhone XS. 

If the previous procedures did not fix the problem and you’re still getting call delays, you can try dealing with the problem through your phone’s hardware components, particularly the SIM card. SIM card errors can also cause calling issues to occur. This is usually the case if the SIM card system has been corrupted from the update. To rule this out, refer to these steps to take off the SIM card from your phone and then reinstall it. It’s a simple way of calibrating the SIM card system on your device. Here’s what you should do then:

  1. Turn off your iPhone completely.
  2. Get the SIM ejector tool then insert it into the small hole on the SIM tray. The SIM tray is found on the side of your iPhone.
  3. Gently push the ejector tool until the tray pops out.
  4. Remove the SIM card from the tray and inspect it for any signs of damage like liquid traces and scratches. If there’s none, place the SIM card back into the tray in the same position and orientation before it was removed.
  5. Push the SIM card tray back into the phone until it’s locked.

Turn on your phone after reinserting the SIM card. Allow it to boot up and then check if it has a good signal prior checking if you have a positive result.

You can also try inserting your SIM card to another compatible phone and check if it still experience call delays even on a different device. If the problem persists on your other device, then that’s more likely due to a faulty SIM card. In that case, you can ask your carrier or service provider for a new SIM card replacement that’s provisioned with the same service your account is subscribed to.
