What is an eSIM?
An eSIM is a built-in digital SIM inside the phone that works without a plastic card and is activated electronically.
An eSIM is a digital version of a regular SIM card. It is fixed inside the phone and cannot be removed. Instead of buying a plastic card and inserting it, you request the SIM from your network operator and activate it using a QR code or the operator's app. It works the same way as a traditional SIM for calls, messages, and mobile data.
In daily use, an eSIM gives you more flexibility. You can activate a new line in minutes without visiting a store, or use two lines at once if the phone supports it. It is also useful when traveling, because you can buy a local or regional plan online and keep your main line active. There is no need to open the SIM tray, which reduces the risk of losing or damaging the card.
When buying, make sure the phone supports eSIM, as not all devices do. Also check that your network operator offers eSIM service and how many lines the phone can handle at the same time. Some phones support one physical SIM plus an eSIM, while others support two eSIMs. Check network support such as 4G and 5G too, because compatibility varies by device and operator.
