How to connect iPhone to private 5G? (Band N78 SA)

I am able to connect android phones to our private 5G network which has PLMN 999-99 and 001-01.

But iphone is not getting connected even after apn addition and supported plmn.

Please help if you know.

I think you should make profile for enabling SA. Check below link:

Also iPhone enable 5G SA/NSA and LTE bands based on surrounding PLMNs, make sure N78 is enabled for your country.
