What is an eSIM?

Travel, international business, managing multiple mobile plans—all these situations require a flexible and efficient solution to stay connected. That's where eSIM technology comes in. In this blog, we'll explore what an eSIM is, the advantages it offers over traditional SIM cards, how it works, and a list of compatible phones. And if you're looking for a modern and convenient solution for your mobile connectivity needs, eSIM could be the future you've been waiting for.

What is an eSIM?

An eSIM, or digital SIM card, is a chip integrated directly into your mobile device. Unlike traditional physical SIM cards, there's no need to remove or insert a card into your phone. Everything happens digitally, through a simple download or profile activation.

The advantages of an eSIM over traditional SIM cards

1. Significant savings on international roaming charges

If you travel abroad frequently, you're probably familiar with the hassle of purchasing local SIM cards to avoid high roaming charges. With an eSIM, it's easy to download and activate a local mobile plan before you even land in your new country. You can compare offers from local operators directly from your phone and choose the one that best suits your needs.

This translates to:

  • A significant reduction in roaming charges.
  • No need to wait to buy a SIM card after your arrival.
  • An immediate connection upon arrival in a foreign country.

2. Simplified switching between operators

Switching carriers with a traditional SIM card can be a tedious process that involves ordering a new card, waiting for it in the mail, or going to a store. eSIM simplifies all of this.

  • You can instantly switch between operators without having to handle a physical card.
  • Ideal for testing promotional offers without long-term commitment.
  • Perfect for users juggling between personal and business plans.

3. More secure than a physical SIM card

eSIMs offer increased protection against loss or theft:

  • Being integrated into the phone, it cannot be removed or inserted into another device.
  • In case of phone theft, access to the eSIM profile can be quickly disabled remotely.
  • eSIMs also reduce the risk of spoofing, which is often done with physical SIM cards.

4. An ecological option

Physical SIM cards require plastics for their manufacture and energy for their distribution. In contrast, eSIM eliminates these needs:

  • Less plastic produced, therefore less electronic waste.
  • Reducing the logistics transport associated with the delivery of SIM cards is an advantage for the environment.

By opting for an eSIM, you are joining a global trend towards more sustainable solutions.

How does an eSIM work?

Activation and management of eSIM profiles

Using an eSIM is easier than you might think. Here's an overview of the typical process:

  1. Choose an eSIM-compatible carrier: Most major carriers worldwide now support this technology. You can visit their website or mobile app to set up an eSIM.
  2. Receive a QR code or digital activation: Once you purchase an eSIM plan, the carrier will send you a QR code to scan or apply an activation via their app. This code contains all the information needed to set up the profile on your phone.
  3. Download the eSIM profile: By scanning the QR code, your phone automatically downloads the eSIM profile and activates it.
  4. Easy management: eSIMs allow you to store multiple profiles on a single device. Switch between profiles via your phone's settings, depending on your needs (for example, switching between a personal profile in France and a professional profile abroad).

eSIM compatible phones

More and more recent phones are integrating eSIM technology. Here is a list of the most popular models that support this feature:

  • Apple: All models from iPhone XS, XR and later.
  • Samsung: Galaxy S20, S21, S22, and Galaxy Z Flip and Fold models.
  • Google: Pixel 3 and newer.
  • Huawei: P40 and Mate 40.
  • Oppo and Xiaomi: Some high-end models.

Before purchasing an eSIM plan, make sure your device supports this technology. Also check if your mobile operator supports eSIM.

The future of eSIM

eSIM isn't limited to smartphones. It's also becoming popular in other devices like smartwatches, tablets, and even smart cars. With the growing reliance on digital and connected solutions, it's a safe bet that eSIMs will become the norm in the coming years, replacing physical SIM cards.

Adopting eSIM today means preparing for a future where connectivity will be simpler, faster and smarter.
