The first method involves using a dual-SIM adapter, which allows users to insert two SIM cards into their device. These adapters are specifically designed for the G973N U7 and can be purchased online.

Converting your with Binary 7 (U7) firmware to dual SIM capability is a specialized process primarily performed by technicians or advanced users . While the South Korean (G973N) variant is physically a single-SIM device, it uses the Exynos 9820 chipset, which inherently supports dual-SIM functionality.

: Modified ROMs used for this conversion often include added features like a native call recorder , which is sometimes disabled in original Korean firmware. Banking Apps

In the combination firmware dialer, enter: *#0808# and select . Then enter *#0011# → press Back (not home) → then Key Input → type Q0000 → press OK . This opens the Service Menu.

Use a tool like (or free method via adb shell ) to execute:

A significant hurdle is that single SIM devices often have only one IMEI. Converting may result in a "generic" or "repaired" IMEI for the second slot to function. ⚠️ Important Considerations

While converting a G973N U7 to a dual-SIM device can be beneficial, there are potential risks and limitations to consider:

The second method involves using an eSIM (embedded SIM), which is a digital SIM card that can be activated and managed through the device's software.
