Schematic excerpt covering the SIM card circuit of an A20s handset, presumably the Samsung Galaxy A20s, in a 2.82 MB PDF. It shows the SIM connector, its supply and data lines and associated protection parts, which helps diagnose no-SIM or SIM-not-detected faults by checking continuity and voltages. Any PDF reader opens it. Only the SIM section is documented, and no board revision appears in the name, so confirm the board version on the phone first.
