failure of the SIM, why I this message all the time?

This means that your SIM card is defective or otherwise expired

Can you make and receive calls and texts?

If so - go out the SIM card - wait about 45 seconds and re insert it back

If not - contact your carrier for a new SIM card

Remove or change the SIM card in your iPhone or iPad - Apple Support
