The Open Source Bluetooth eSIM Card Reader manages eSIM profiles on your Switch adapter without going through a phone. Insert the card, connect the reader, scan a QR code, and the profile is written to the adapter — then move the card to whichever handset you're using. It's pocket-sized, the firmware is open source, and no account or login is involved.
Who it's for
Anyone who can't or would rather not load profiles from their phone. That includes iPhone owners, people running several handsets, anyone provisioning cards for family or a team before a trip, and developers who want to see how the thing works rather than trust a black box.
If you own an Android phone and only use one device, the free Switch app already covers you — the reader is what removes that dependency.
How it works
-
Insert your Switch adapter into the reader.
-
Connect over Bluetooth or USB Type-C.
-
Scan the QR code from your eSIM provider.
-
Move the card to your phone. The profile is on the adapter and ready to use.
Profiles live on the card, not the phone, so the same card moves between devices with nothing to re-download.

What does "open source" mean here? The firmware is published, so you can audit what the device does with your profile data or modify it yourself.
