2UUL SM01 Dual SIM Card Checker – Fast, Reliable SIM Testing for Mobile Repairs
In mobile repair work, diagnosing problems quickly can make all the difference between a smooth repair and wasted hours. When a phone fails to detect a SIM card, it’s not always clear whether the fault lies with the card itself, the SIM slot, or the phone’s internal circuits. The 2UUL SM01 Dual SIM Card Checker is built to solve that problem—allowing you to instantly test both SIM slots without inserting cards into the phone’s original tray.
This compact, easy-to-use tool helps technicians confirm SIM card detection within seconds, saving valuable time, avoiding unnecessary disassembly, and ensuring more accurate diagnoses.
Why Every Technician Needs the 2UUL SM01
Many repair scenarios involve testing SIM card functionality, especially in dual-SIM smartphones. A faulty slot, a damaged SIM reader, or even a defective SIM card can all cause detection issues. The 2UUL SM01 offers a quick, safe, and reliable method to determine where the fault lies—helping you troubleshoot with confidence.
Instead of repeatedly inserting and removing SIM cards from the actual phone slots—which can damage delicate connectors—this testing board acts as an external bridge. It gives clear results fast, making it perfect for both shop-based repairs and on-site service calls.
Key Benefits at a Glance
1. Instant Results
The 2UUL SM01 eliminates long trial-and-error processes. Simply connect the tester to the phone’s SIM interface, insert the cards, and see if they’re detected—no extra steps required.
2. Dual-SIM Ready
Many budget testers only handle one SIM at a time. The SM01 tests both slots simultaneously, saving even more time during busy repair work.
3. Pocket-Sized Portability
At just a few centimeters in size, this tester fits easily in a pocket or small toolkit. Whether you work in a shop or travel for field repairs, it’s always ready to use.
4. Safe for Phone Hardware
By avoiding repeated use of the original SIM tray, you reduce wear and tear on the phone’s connectors—helping to prevent additional damage during diagnostics.
5. No Power Supply Needed
With a plug-and-play design, the SM01 doesn’t require charging, batteries, or complicated setup. It works the moment it’s connected.

Using this tool is simple and intuitive:
