Hi Friends.
What may be the possible causes that this ONE PLUS 9 PRO 5G (SA+NSA) Supports both.
But UE is not stable on SA Network.
Network is stable for some time (1, 2, 5, 10) minutes, but sometimes even after keeping it on aeroplane mode or restarting it no network found.
Is it a Qualcomm phone?
If so, you can check the modem logs using QXDM.
Update:
The problem has resolved itself but not completely, when we reach in the 5G SA Coverage Range it never connects itself, it has to restart or have to enable flight mode then disable.
5G SA Transmitting Antenna.
Using another Samsung Galaxy Ultra, there is no issue with that.
