[.:SARCAR:.]

check vsim voltage 2.8v at C2700 (marked in picture) . if voltage not obtained replace L2704 then check , if still vsim voltage not obtained at marked point then replace avilma.

if vsim voltage ok but insert sim problem aries then reball avilma first , if not help replace it.

there is no sim esd filter used in 2730c . all sim lines goes into avilma directly.
