What is an eSIM adapter, and how does it work?

An eSIM adapter is a programmable physical SIM card that holds digital eSIM profiles. You insert it into your device's existing SIM slot, then download carrier profiles onto it using an app or a card reader. Your device treats the adapter as an ordinary SIM card, so it works even on hardware manufactured years before eSIM existed.

Switch adapters follow the GSMA eSIM standard, which means they accept QR-code eSIM profiles from most providers, including Airalo, Holafly, Ubigi, and hundreds of regional carriers.

Does the Switch eSIM Adapter work on iPhone?

Partly — and the distinction matters before you buy.

iOS does not permit third-party apps to write eSIM profiles to an external card. An adapter inserted into an iPhone can use a profile that is already loaded, but cannot download, delete, or reorganize profiles from the phone itself. This is an Apple restriction and it applies to every eSIM adapter on the market, not just Switch.

The workaround: the Switch Bluetooth eSIM Card Reader handles provisioning independently of your phone. You load profiles onto the adapter through the reader, then insert the adapter into your iPhone. Full profile management on iOS, without needing an Android device.

If you own an iPhone and no Android phone, buy the Max + Bluetooth Reader bundle ($28.54), not the adapter alone.

No account, no servers, no telemetry

Switch does not require registration to use an adapter. Profile provisioning happens locally between the app or card reader and the card itself. Switch operates no server that stores your eSIM profiles, carrier credentials, or device identifiers.
