What happens to your physical SIM when switching to eSIM

When you switch to an eSIM, your physical SIM will be permanently deactivated and can't be used again. Your entire service, including your phone number, plan, and any remaining credit, transfers to the eSIM.

You should dispose of your old physical SIM card properly, and it is not recommended to swap to an eSIM unless you have specific need for one as eSIMs will require a SIM swap every time you change or upgrade phones going forward as they are bonded to each particular device.

Please note that we're getting ready to launch eSIM in October 2025, so some of the information in this article may not be valid until after this feature is released.
