There are pros and cons to any product or service. Researchers highlight some eSIM concerns in their paper, “eSIMplicity or eSIMplification? Privacy and Security Risks in the eSIM Ecosystem”, such as:
- It can be trickier to transfer an eSIM than a physical SIM.
- Users are taking on some complicated provider operations.
- There are concerns about cybersecurity related to eSIMs
Trouble switching eSIMs
If you damage your phone, you can simply put a physical SIM in a different device. Unfortunately, eSIMs aren’t quite as simple.
You may encounter logistical hurdles when transferring eSIMs between devices if an eSIM is tied to a device. Unfortunately, to prevent unauthorised eSIM sharing, operators are tying eSIMs to singular devices, making it harder to switch devices. This rigidity runs counter to the flexibility of easy local network access.
Trouble managing eSIMs
Till eSIMs, the provisioning and management of subscriber SIM profiles were done by operators. Now, eSIMs are moving this administrative process to users through Remote SIM Provisioning (RSP). Users may encounter several issues when trying to manage their eSIMs. For example, in some cases, deleting an eSIM profile while the device is offline may create a conflict between the device and the server. If one thinks the profile is active and the other doesn’t, it can hinder profile reactivation.
