I’m wondering how 5G is currently being pushed out to customers...
I ordered a 12GB/Unlimited calls/Unlimited texts SIM on the 30/5 and inserted it into a Oppo Reno 4 Z 5G handset. It has 5G listed and enabled in the handsets settings menu and we get 5G signal too.
I ordered another 12GB/Unlimited calls/Unlimited texts SIM on the 14/6 and that too is in another Oppo Reno 4 Z 5G handset. However, no 5G is listed in the handsets settings menu (only 4G/3G/2G) and so no 5G signal.
I have tried turning off the phone and turning it back on. I have also performed a full factory reset of the second handset and setup a new but still no 5G. So, it appears that the second SIM isn’t provisioned for 5G.

Fixed - I left the second SIM in my S21 Ultra 5G for 10 minutes and eventually up popped 5G.
Put it back in the Oppo Reno4 Z and my son now has 5G on that device too.
