So it seems eSim is very different from physical Sim, there will be residue that will not be factory reset as the hardware remains even when there is change of operators. Genius everywhere.problem solved. guided by a guy in eight telegram group
i used to hide my caller ID for Simba e-sim line. now duno why it is still in effect when i have terminated it.
anyway, the guy asked me to try Hiding Caller ID (*31#) and unhiding Caller ID (#31#).
It worked!
