Try to do a force restart -> Force restart iPhone – Apple Support (UK)
If it doesn't help, remove and reinsert the SIM card.
If it doesn't help contact your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.
Also ask to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.
If it doesn't help, see these Apple articles below:
