eSIM: What It Is, How to Activate It, and Compatible Smartphones


Looking for a free prepaid SIM with 10 CHF credit included?

Since 2016, with the advent of the first wearable devices and later with the release of smartphones compatible with this technology, eSIMs continue to be one of the ongoing revolutions in the telecommunications sector. eSIMs are virtual SIM cards, not physical, and technically they are actual codes that can be applied to a circuit already present inside the smartphone or connected device.


Wondering how they work, how much they cost, the pros, and cons? Read our eSIM guide to become an expert.


What Does eSIM Mean and How Do Virtual SIMs Work?

eSIM or embedded subscriber identity module is a SIM card integrated into the cellphone that cannot be removed and allows you to activate a phone number without needing a physical SIM card.


In phones compatible with eSIMs, there is already an integrated circuit with the device's circuits, enabling eSIM activation without inserting any external hardware. Activation is as simple as scanning a QR code: scan the code, and then, from the smartphone's settings, the related phone number will be activated.

eSIM Advantages: All the Pros of Virtual SIMs

Below are the main advantages of virtual SIMs:

  • No Risk of SIM Loss: Those who use their SIM continuously across different devices may risk losing the physical card. This especially happens when traveling abroad and needing to purchase a prepaid mobile tariff for tourists. In these cases, opting for an eSIM can be advantageous, eliminating the need to remove the original SIM card and reducing the risk of losing it.

  • Dual-SIM Option: Another advantage of phones compatible with eSIMs is the ability to install multiple phone numbers on a single device, similar to dual-SIM phones. This allows access to a greater number of services differentiated based on the subscribed tariff with the various eSIMs.

  • Easy Purchase and Installation: A third advantage of virtual SIMs concerns number portability. When canceling a mobile subscription, there's no need to physically replace the SIM card to make room for the new one. The process is as simple and automatic as scanning a QR code, avoiding the wait for the physical card to arrive by mail.

  • Eco-Friendly Choice: Avoiding the purchase of a physical SIM saves CO2 emissions by avoiding the production and exploitation of raw materials.

  • More Phone Memory: A final advantage of eSIMs primarily concerns smartphone manufacturers. With the increasing adoption of this type of virtual SIM, it will be possible to eliminate the slot for inserting the physical card, making room for increased device memory.

eSIM for Travel: An Alternative to Convenient and Economical Roaming

For those planning a trip abroad, eSIMs are an excellent alternative. You can purchase an affordable eSIM before your departure and activate roaming services without having to buy a physical SIM upon arrival.

How to Buy and Activate an eSIM?

Depending on the selected mobile operator, you can purchase eSIMs online or in a physical store. Buying online allows you to receive the QR code and activation instructions within minutes, avoiding the wait times associated with traditional SIMs.

To activate an eSIM, scan the QR code provided at the time of purchase and follow the instructions for your specific cellphone model. Sometimes, a verification code is required, either from the email sent by the operator or received via SMS. Generally, you'll always need to verify your identity before using the connection features.

eSIM: Which Swiss Operators Offer It?

As of today, the adoption of eSIMs in Switzerland is still limited, as not all Swiss mobile operators offer them. Even when available, eSIMs are not always a free alternative, making them not the preferred choice for users looking to save money.


Here's a breakdown of the costs of eSIMs from the major Swiss operators.
