iPhone 4S says NO SIM $ problematic ios stuff ios/hardware , assistance please

On March 29, 2015, Posted by , In iPhone, With Comments Off on iPhone 4S says NO SIM $ problematic ios stuff ios/hardware , assistance please

I have an iPhone 4S When I insert a sim card into the phone it says NO SIM.


I have tried

1) Restoring the phone
2) Resetting the Time on the phone.
3) Put the motherboard in a different phone.

The Baseband and Modem Firmware all function
as does the WiFi. The Phone is currently stuck on the ACTIVATION
screen because it will not read sim card.

In another thread someone said it is Resistor R3 on an iPhone 4S
I dont have a schematic so can someone tell me how to fix

    I have tried everything except remove components from the board.

    1)I have tried a different sim card.
    2) I have checked the sim card reader it is perfectly fine
