The 2UUL SM01 Dual SIM Checker Card Quick Test Board is a compact and efficient diagnostic tool designed for testing SIM card functionality and SIM slot performance in mobile phones. It enables technicians to quickly determine whether a fault lies in the SIM card, SIM reader, or motherboard circuit, helping to avoid unnecessary repairs and save time.

This tester supports dual SIM testing, allowing both SIM slots to be checked simultaneously. With its plug-and-play design, there is no need for additional power, software, or complicated setup—simply connect the board, insert SIM cards, and power on the device to view results instantly.

The SM01 acts as an external testing bridge, reducing the need to repeatedly insert SIM cards into the phone’s tray, which helps protect delicate connectors during repair work
