What are eSIM cards?

An eSIM, or embedded SIM, is a virtual SIM module that replaces the physical SIM card in mobile devices. Unlike traditional SIM cards, this chip is embedded within the device and can be programmed with multiple network profiles.

Virtual SIM offers several advantages over traditional SIM cards:

Flexibility. Users can switch between mobile network operators without the need to physically replace SIM cards.

Convenience. Particularly beneficial for travelers, eSIM allows activation of local plans without purchasing new SIM cards.

Environmental Impact. By eliminating physical SIM cards, virtual SIM helps reduce electronic waste.

How eSIM Works?

Devices with eSIM have a specialized software interface that manages connections to different networks. Users can add, delete, or switch between plans without physically changing the SIM card.

Adoption and Availability

Currently, eSIM technology is supported by approximately 400 mobile operators worldwide. Users can check their device’s compatibility by navigating to Settings > Connections > SIM card manager.
