More compact, more secure, more flexible, and more responsible, the eSIM or embedded SIM card is making its mark in the world of telephony. This rapidly growing device is particularly well suited to mobile professionals, expatriates, and long-haul travelers, as it eliminates roaming charges.
More than 250 operators worldwide have already integrated physical-free technologies into their mobile subscription management, signaling a gradual shift toward a fully digital ecosystem. This trend is part of a broader transition toward the dematerialization of telecom services, where the elimination of physical SIM cards is much more than just an ecological gesture.
It marks a profound transformation in the logic of mobile data activation, portability, and security. The use of a chip integrated directly into the device (eSIM) redefines the standards of flexibility, immediacy, and security expected in modern telephony. In this article, we discuss the technical, regulatory, ergonomic, and environmental dimensions of this evolution.
Using an eSIM in France: a controlled rollout with multiple implications
In France, the use of eSIMs is gradually becoming more widespread as incumbent operators and MVNOs (mobile virtual network operators) adapt their infrastructure to this embedded technology. This chip, which is soldered directly onto the device’s motherboard, eliminates the need for a removable medium and introduces a new way of assigning network profiles. To use an eSIM in France, activation requires downloading a digital profile via a QR code, a secure link, or directly from the phone settings, using the management interface provided by the operator.
The challenge is not limited to convenience. France, through the ANFR (Agence nationale des fréquences), ensures the interoperability of devices and compliance with GSMA specifications, thus guaranteeing continuity of service for travelers and professionals on the move.
More secure subscription management
The software integration of eSIMs paves the way for real-time monitoring of subscription settings, offering users the ability to switch from one plan to another without any physical manipulation. This model eliminates the risks associated with SIM card loss or theft, while strengthening security against swap fraud (unauthorized SIM card exchange to steal a number).
Operators can thus combine enhanced authentication layers with line activation, using single-use cryptographic protocols or biometric double verification. For their part, businesses are now using eSIMs to remotely manage fleets of business devices via MDM (Mobile Device Management) platforms, with unprecedented control over access permissions and network configurations.
