What is an eSIM?
An eSIM is a digital SIM card that is already built into your device. You can easily activate it via a QR code or an app, without needing a physical SIM card. It is ideal for traveling or using multiple subscriptions on a single device. Many modern smartphones, tablets, and smartwatches support eSIM.

Will I keep my own number?
Yes, you will keep your own number! Note that answering calls may incur additional roaming charges from you current provider. Therefore, e-simmy recommends making calls and sending SMS via WhatsApp, which uses your data package and incurs no additional roaming charges.
