How to avoid roaming charges on your Indian SIM
Quick answer
Before you land, turn Data Roaming off on your Indian SIM and choose the Olysim eSIM for mobile data. Your Indian SIM can stay on for SMS, but it will not use any roaming data.
Most surprise roaming bills come from the Indian SIM using data by itself abroad. Two switches stop it.
