ENDC at Samsung phones (like S21) doesn’t work for all PLMNs, operator should communicate with Samsung for enabling ENDC.

Yes, in NSA it is one type of carrier aggregation between 4G & 5G.

A better word is Dual Connectivity.

Since in CA only 1 CRNTI is used by UE but in DC a single UE use 2 crnti mean separate CRNTI for 4G and 5G.
