An eSIM is a digital SIM card that's built into your device. Instead of inserting a physical SIM card, you can download and activate your mobile plan digitally. It works exactly like a regular SIM card but gives you more flexibility to switch between carriers and plans.

Most modern smartphones, tablets, and smartwatches support eSIM. This includes iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and many others. Check our compatibility guide for a complete list.

After purchasing, you'll receive a QR code via email. Simply scan this code with your device's camera in the cellular settings, and your eSIM will be activated automatically. The whole process takes less than 2 minutes!
