hello ,
there is no sim esd filter used in nokia e71 . all sim data lines goes into avilma directly .
so we need to check vsim voltage at C2700 while sim inserted . it should be 1.8v-2.8v
if this voltage is missing or abnormal then this type of problem Aries . we first remove d marked chipcap (C2700 / marked in first picture) & measure d vsim voltage . if still missing this voltage then try to reball or replace avilma.
if vsim voltage ok but same insert sim problem then we also need to reball or replace avilma .
