Hi zeelvaghani0,

Remove SIM => Clear data of SIM toolkit from Settings => Apps => Insert Sim after switching off Phone.
Use Mobile Manager Cleanup feature.
Also Wipe Cache Partion from Android Recovery.

Check whether issue persists with other SIM Cards and also check in Safe Mode https://www.asus.com/support/FAQ/1005163/

Hi Zeelvaghani,

Kindly follow the step mentioned above and revert.
