If there is no one time voltage at VSIM, check the lines to CPU (see the service manual)

Had the same probem last week. turns out the glued CPU is making the problem. Sticked some thick sticker on the CPU so it will be pressed against the middle casing/body when screwed.

good luck
@zoboz...

The same as above as the phone can detect SIM card and communicates with it , accepts some of them and refuses some of them .
That means that the SIM card interface module to the ccont is working normal ( may be the problem is 3 or 5 volts - but 1800/900 Mhz is not SIM module's matter !!)
