The tech specs for the ASUS Zenfone 9 (dual SIM)
state in the "SIM Cards" section:
Dual slots: 5G*+5G or 4G dual-SIM / dual-standby support
If I have two SIM cards in the phone does it mean that each one cannot
use the 5G network? Or perhaps it means that SIM card #1 can use the
5G network and SIM card #2 not?
