Detailed information
An eSIM is a digital virtual SIM card that is loaded into your device and allows you to use mobile communications without a physical SIM card. The eSIM card has the same capabilities as its plastic counterpart: it can be blocked if the phone is lost, and can also be reinstalled on a new device.
eSIM is an independent module and does not depend on the presence of other SIM cards in the smartphone. A mobile device can support both a physical SIM card and an eSIM card at the same time. If you wish, you can replace your current SIM card with an eSIM. More information here.
Prepare your QR-code for reading (on paper or on the screen in your Personal Account). Make sure that your old smartphone has an Internet connection (WI-FI or data) and completely remove the eSIM profile on it. Then go through the eSIM activation process on your new device by scanning the previously prepared QR- code. More details in the “How to activate” section.
Attention! For customers who were issued an eSIM before September 13, 2022, the owner of the number must contact the A1 store to replace the old eSIM with a new eSIM or physical SIM.
If you lose the QR code on paper, you can view it in your profile in your Personal Account (including when replacing a SIM in the My A1 application or going to A1 store with an identification document.
