What are the Benefits of eSIM ?

eSIM benefits everyone like the device user , operator , distributers , device manufacturer and so on .

·        It stores multiple cellular profile and that why it works seamlessly across the world.

·        It doesn’t requires a dedicated slot unlike normal SIM cards. Hence it is ideal for the products that have small form factor (basically small in size like a watch ).

·        There is no possibility to lose the card as it is not within the reach of the owner.

·        It is equally secure as the removable SIM cards .It also supports integrity of billing process during roaming scenarios.

·        eSIM have simple management of subscription and connection .

 
What are the drawbacks of eSIM ?

·        If your phone or the device with eSIM some how get damaged or dead then it is not easy to retrieve data  as it is in case of removable SIM .  Therefore , users has to rely on cloud storage to retrieve the data such as messages, contacts and other important things.

·        I am not sure that this is disadvantage or advantage that a person may get in problem who do not want to be tracked when they using eSIM. But if he/she have removable SIM was able to remove the SIM and get safe from tracking.

·        User who like to use different mobile can  change its normal SIM  anytime but not in case of having eSIM.
