An eSIM (embedded SIM) is a digital SIM built into your device that allows you to connect to the internet without needing a physical SIM card. It works just like a traditional SIM, but with no need to insert or swap a tiny card. eSIMs are especially convenient for travelers as they help avoid high roaming fees and make it easy to switch between mobile networks.

eSIMs work on smartphones, tablets, smartwatches, and even smart cars. You can install multiple eSIM profiles on one device and easily switch between networks.
