sim detect switch is 4 pin , in which 3pins r connected with gnd & pin 1 goes to sim detect circuit through R3201 (which I marked in picture) .

so we need to connect R3201 with gnd to detect sim by mobile , but remember it's only testing purpose . u should replace switch if broken .

yep , might have .

if u permanent short (sim card detect signal) with gnd then mobile try to always sense sim detection . with battery inserted it's risky . risky for electronic-surge issue .
but without battery no problem . but actually it's not all time possible to remove battery for change or insert sim card .

so I advice u to replace sim detection switch with new one . if not found use from another dead unit . or from china dvd player .

@d-Artigo ,
bro read post carefully/fully , thread starter want to know about sim detection switch . cause it's broken . that's why sim not detect by mobile.
