> 5G Standalone security and privacy requirements

> To help ensure compatibility of iPhone and cellular iPad devices on private 5G SA networks, infrastructure vendors must adhere to the following security and privacy requirements:

> Privacy concealment: The Subscription Concealed Identifier (SUCI) must use a non-null protection scheme. This can be achieved through either an on-SIM SUCI calculation or an ME SUCI calculation, as outlined in TCA 2.3.1 and 3.1 specifications. For detailed information, refer to the 3GPP Technical Specification 33.501.

This pertains to private networks rather than public operator networks, but it certainly seems to imply that use of SUCI is an expectation on 5G SA networks (private in this context).

In the US, the T-Mobile 5G SA eSIM and SIM cards all have SUCI at least. I don’t have any idea about other networks.

One thing I've always wondered is if you need a R15 sim card for it to use SUCI or if the old cards can receive provisioning to do it. I know for a fact you can use any USIM on t-mobile (so it had to support at least 3G) and it will work in the latest 5G devices without issue on SA.
