How do I fix an invalid SIM error on my iPhone 15 Pro Max?

Since yesterday, I’ve experiencing the issue of sim failure and invalid sim on my device. I’ve done all the steps removing sim card, resetting the network settings and updating the phone but still no positive result.

Can anyone come up with suggestions??

SIM card and SIM failure are carrier issues. Apple cannot help on this.

Please contact your carrier for assistance. They will likely need to send you a new SIM card.

You may need to temporarily use another phone to contact your carrier if your phone is not able to make calls, text, etc.
