If it's the SIM card that's actual invalid and not a problem with the phone itself, then you get a new SIM card.

Thanks for the question.

Make sure that the device you are using, works with the carrier you got your SIM from CDMA vs GSM

Not all SIM cards will work with all phones. Additionally, ensure that the SIM you are using has been activated.

Hope thus helps
