SIM card circuit schematic for the Samsung SM-A22 5G, contained in a 5.25 MB PDF. It covers the SIM tray connector, its supply, clock, reset and data lines, along with protection parts and the detect signal. Use it to diagnose no SIM or SIM card not detected faults by checking SIM voltage and continuity to the processor. Any PDF reader opens the file; confirm that the board in hand is the 5G version of the A22, as the 4G variant has a different layout.
