Good to know
- Make sure your phone supports eSIM — check your phone if you haven't already.
- Your phone must be unlocked (carrier-locked phones, especially some US Samsung models, can't add third-party eSIMs).
- You don't need to remove your physical SIM — keep it active for incoming calls/texts while using the eSIM for data.
