> Number porting should require an SMS to the existing SIM
This is done by some carriers in Russia as far as I remember.
> with the ability to respond NO to cancel the proces
There is no such possibility, but you can visit carrier's representative.
> A mandatory time delay (12 or 24 hours) could be imposed.
Some carriers do this for SMS. Here is a quote from one of the carrier's website:
> To protect you from scammers, after replacing a SIM card SMS messages from banks and commercial online services will be blocked for 24 hours. You will be able to send and receive SMS from other users and popular messengers and applications instantly.
> SMS is an extremely powerful authentication factor
But it discloses person's identity and location.
