SIM Failure message on iPhone

Hi Jengel11,

That's a good step to try, resetting the network settings, but that is something you should seldom have to perform. There are steps you can take to help narrow down if this is an issue with the physical SIM card or the SIM card reader. We'll place the link and steps found below. Skip any you have already tried.

If you see 'invalid SIM' or 'no SIM' on your iPhone or iPad - Apple Support

1. Make sure that you have an active plan with your wireless carrier. 

2. Restart your iPhone or iPad.

3. Check for a carrier settings update. Go to Settings > General > About. If an update is available, you'll see a prompt to select OK or Update.

4. Remove your iPhone SIM card or iPad SIM card from the SIM card tray and then put the SIM card back. Make sure that the SIM tray closes completely and isn’t loose. If you use a SIM tray from a different model iPhone, iPad, or from another phone manufacturer, it might not fit properly.

5. Try using another SIM card. If you don't have one, go to your carrier's retail store and ask them to test with another SIM card. You might need to replace your SIM card.

If you still see an alert about your SIM card, contact Apple support.

Following these steps may help with resolving the message you see popping up about the SIM card. If not, follow the link above for contacting Apple Support.

Take care!
