I have put my old SIM-card into my new iPhone 12, and the provider has confirmed that the card has been activated.  I can send and receive email, but I cannot activate iMessage, SMS, What'sApp, Facetime, &c. I keep getting "Waiting for activation."  I have tried resetting the network, but that has made no difference.  What am I doing wrong ?
