i know it is in spanish but i found something :
0 1 2
3 4 5 Controlador de sim
6 7 8



Para que orienteis bien la placa el cero es el pin que esta vacio en la placa base. (logicamente tendreis que retirar el controlador sim de la placa base)

hacer los puentes:

puentes

1 al 2
3 al 5
6 al 8

Esto lo hemos testeado y rula a la perfeccion incluso en terminales dañados por liquidos.

yes your connections are right ,

33X 1+1, 2+2 ,3+3
you can use these jumpers in most of nokia phones . which uses R388
(ESD) in sim card ckt ..

may be your conection wrong , there is a posibility to connect 1+2 ( 3+3)

then i tested , 7610,3200,6610,6230,6310,... all working fine

you can test your connection of sim contact , after jumper setting

with ohm meter....

Dear brother,,
Is jumper means " pin 1 of R388 to pin 1 of sim socket " ?
And pin 2 of R388 to pin 2 of sim socket?
And pin 3 of R388 to pin 3 of sim socket?

Thanks you so much..

Dear mandu,,,
Thanks you very much for your kind.

I have 6230 insert sim problem.
I will try to solve with your solution.

But I am not so understand for R388.
Did you mean that I can remove R388?
Can I make jumper on the PCB without R388?

Sorry for your time and my question.

Have a nice everything

hi mate . first you remove R388 and clean pcb then make jumper
it need little time and care , because very small print on pcb , if you
make more heat , it will remove copper from pcb ...
if you cant make jumper you can put a dual rasister (1+1kohm) insted of
jumper 1+1 and 2+2 and put one jumper for 3+3 it is easy

try ...and post result ..
