An embedded SIM (eSIM) works in the same way as a regular SIM card to provide you with network reception. But unlike a SIM card, you don't have to physically insert an eSIM—just download and install it on your device and you're all set.

As long as your device is compatible with eSIMs and carrier-unlocked, you should be able to set up eSIMs without a hitch. However, devices originating from mainland China, Hong Kong, and Macau do not support eSIMs. You can check if your device is compatible here. If you are unsure, we recommend checking with your device manufacturer directly.
