9eSIM B1: The Bluetooth Physical eSIM Adapter

Transform your standard SIM slot into a global eSIM hub. The 9eSIM B1 is a revolutionary physical nano-SIM card that brings wireless eSIM connectivity to smartphones lacking built-in eSIM support.

What Makes It Different? Older physical eSIM adapters required external USB card readers because operating systems like Apple’s iOS and Huawei’s HarmonyOS block third-party apps from writing data to the SIM tray. The 9eSIM B1 solves this by integrating a microscopic Bluetooth Low Energy (BLE) chip directly onto the card. It acts as its own wireless reader, allowing you to bypass these restrictions and download profiles over the air.

Key Features & Benefits

• No Cables or External Readers: Download and install carrier profiles wirelessly using the 9eSIM companion app and your phone’s Bluetooth.

• Massive 30-Profile Storage: Equipped with a premium 1.1MB eUICC secure vault, the card has the capacity to hold up to 30 different global carrier profiles at the same time.

• App-Free Daily Switching: Bluetooth is only active during the initial download. For daily use, simply switch between your saved networks in seconds using your phone’s native SIM Toolkit (STK) menu—no app or internet connection required.

• Zero Battery Required: The card has no battery to charge or degrade. It draws the microscopic power it needs directly from your phone’s SIM tray pins.

• Bank-Grade Security: Built to GSMA standards with end-to-end encryption. Your telecom credentials are cryptographically locked during the Bluetooth transfer, making wireless interception mathematically impossible.

Important Compatibility Requirements Please verify your device meets these three conditions before purchasing:

1. Physical Nano-SIM Slot: Your device must have a physical SIM tray. (Note: This product is not compatible with eSIM-only devices, such as United States models of the iPhone 14, 15, and 16).

2. Carrier Unlocked: Your smartphone must be network-unlocked to accept third-party carrier profiles.

3. App Support: Initial profile downloads require the 9eSIM companion app, available for iOS and Android (requires Android 10 or newer).
