Is not activate SIM cards

If your iPhone can't be activated or an alert says the activation server is unavailable or the SIM card is unsupported, read this Apple document --> If you can't activate your iPhone or iPad (Wi-Fi + Cellular) - Apple Support

This looks to me like a message saying that your iPhone is carrier-locked – and that the SIM you tried to use is not from the carrier to whom the phone is locked. Thus you are not allowed to use that SIM with that phone.

If the phone is carrier-locked, only the carrier who holds the lock can release it – if they choose to do so.
