Why iPhone users and multi-device travelers choose the Switch eSIM Card Reader
Most eSIM adapters depend on an Android app to load profiles. If you use an iPhone, juggle several handsets, or set up SIMs for family or a team, that dependency becomes a wall. The Switch eSIM Bluetooth Card Reader removes it. It is the only step between your carrier's QR code and a working eSIM on your adapter — and it happens entirely off your phone.
How it works — 4 steps, under 2 minutes
-
Insert your Switch eSIM Adapter Pro or Adapter Max into the reader.
-
Connect the reader over Bluetooth or USB Type-C.
-
Scan the QR code from your eSIM provider.
-
Move the card to any phone. The profile is on the adapter and ready to use.
Download, activate, or deactivate profiles whenever you need. Because profiles live on the card, switching phones is a physical swap — no re-downloading, no carrier re-verification.

FAQs
What is a Bluetooth eSIM card reader?
A Bluetooth eSIM card reader is a small device that writes eSIM profiles onto a removable eSIM adapter card without using a phone. The Switch eSIM reader connects via Bluetooth or USB-C, scans a carrier QR code, and stores the profile on the adapter.
Does the Switch eSIM Card Reader work with iPhone?
Yes. Because the reader manages profiles independently of any phone app, iPhone users can load profiles onto a Switch eSIM Adapter Max and use it in their iPhone.
Do I need this if I have an Android phone?
Only if you don't want to use the free Switch eSIM Android app, or you manage adapters for multiple devices or people.
Can one reader manage several adapters?
Yes — one card at a time. A single reader can serve as many Switch eSIM adapters as you own.
Is an account or login required?
No. No account, no login, and no profile data is stored on Switch eSIM servers.
