# Do I need to remove my physical SIM to use an eSIM?

No, you don’t need to remove your physical SIM card to use an eSIM. Most modern smartphones support dual SIM functionality, which means you can use your physical SIM and an eSIM at the same time.

This setup is especially useful for travelers:
* Keep your main number active on your physical SIM for calls and texts.
* Use your eSIM for data while abroad, often at better local rates.
* Easily switch between networks in your phone’s settings.

However, if you’d like to use only your eSIM, you can remove the physical SIM — it’s completely up to you but not recommended for the reasons above.
