  3. After a second or two, press the flight mode icon again to disable it.

You may perform the above steps and restart the iPhone if the “SIM not provisioned” error warning keeps appearing.

4. Install the Pending Carrier Update on the iPhone

Service providers sometimes push new updates in the form of bug fixes or adding new features to their existing services. Normally, when your iPhone is connected to the network, these updates are installed automatically.

Still, it may happen that the latest updates cannot be installed due to some reason. You can manually check for these updates.

  1. Go to the Settings app and launch it.

5. Manually Activate the SIM card 

Normally, a SIM card gets activated within 24 hours of being registered and put on a phone. Sometimes, users face the SIM not provisioned error when the SIM does not activate within a 24-hour window. If you face a similar situation, try manually enabling the SIM card.

  1. Visit the website of the service provider.
  2. Sign in using the steps mentioned on the site.
  3. Enter the phone number(of the new SIM) and try to activate it.

Additionally, contact the customer support of the service provider and take help from them to activate the SIM card.

6. Perform Another Porting for the SIM card 

Sometimes, the Sim Not Provisioned error may occur due to incorrect porting. It may specifically say that SIM 1 is not provisioned or SIM 2 is not provisioned. You can eject and re-insert the SIM card.

If that doesn’t solve anything, consider contacting the service provider’s support to which you ported the SIM. Follow their instructions to perform another porting.

7. Clean the SIM Card

The SIM card may require a cleaning. Dirt or grime may have accumulated on the SIM contact point after years of use. Carefully eject the SIM card and clean the golden part with a soft cloth. Then insert it back into the SIM tray. Restart the iPhone and this should possibly fix the SIM not provisioned error.

8. Contact your Service Provider 

When none of the above troubleshooting tips are working, you should contact the customer support of your service provider. If your phone cannot make calls, you can use social media handles to reach out to the tech support team of your service provider.

When a support executive is connected to you, explain the issue to him. Then follow the possible solution he will offer in fixing the SIM not provisioned error on your iPhone.

I hope these troubleshooting tips will suffice in helping you fix the SIM not provisioned error in your iPhone. A SIM card is very important to make calls, use the internet and enjoy other important telecom services. So, the problem should be fixed at the earliest.
