What is eSIM?

eSIM stands for “embedded SIM” (also called eUICC). It’s a standardized SIM chip open to multiple mobile operators globally. Meaning, if you have an eSIM you don’t have to replace one SIM card with another when switching carrier. Since the eSIM can be programmed remotely, it allows you to choose another carrier by just messaging the old and new provider. It is fascinating because, in a country like India where the subscriber has to stand 5 hours in a long Queue just to get a Reliance JIO SIM card, eSIM card is a blessing.
