But what does this mean for you? Imagine activating or changing your plan with SFR, Orange, or Free with a single click, without having to fiddle with nano or mini SIM cards. That's the promise of eSIM card : a virtual space for your number, simplified use, and ultra-fast connectivity. The future of telephony is here—are you ready to enjoy it? Follow us to explore the eSIM card, this little chip that makes it all happen.
ESIM: The Sim of the Future
From the 1990s to the early 2000s, cell phones featured traditional SIM cards to 1FF format, equivalent to the size of a credit card. Operators such as SFR, Orange, Free, etc. quickly adopted the 2FF format, also known as mini-SIM (often referred to simply as SIM card). The 3FF and 4FF formats emerged in 2010, with the micro-SIM card and nano-SIM card versions. The latter has virtually no plastic backing and is the minimum size for a SIM card removable.
Then, a new, tiny SIM card format was introduced with the Samsung Gear 2 watch: the eSIM cardSince then, many manufacturers have popularized it and encouraged their customers to use eSIM in their mobile devices. Among them are Apple with the iPhone Xs, Samsung in its high-end models since the Samsung Galaxy S20, and Google starting with the Pixel 3. Today, all brands offer at least one smartphone eSIM compatible, although this new technology is often reserved for their top-of-the-range products.
Here's an image showing the difference between a physical SIM card and an eSIM.

What is an eSIM?
The eSIM is a permanent version of the SIM card integrated into the device's motherboard, offering significant advantages. Its small size frees up space for a larger battery, while the absence of a SIM tray enhances the waterproofing and durability of smartphones. Changing carriers or numbers remains simple thanks to easy modifications to the chip. Quick activation of the phone line is possible with a call to the carrier when purchasing a compatible device. In terms of security, eSIM renders a stolen mobile phone unusable and allows for quick deactivation of subscription information if necessary.
