You may trace each of the SIM card pin connectors down to each corresponding capacitors. Check the SIM supply voltage (VSIM) for about about 2.9 volts on the corresponding capacitors and VSIM pin connector.
All the SIM data signal is feeds to and from the AVILMA IC, there is a possibility that the SIM error problem is caused by a faulty AVILMA chip, reworking or replacing it will only fix the problem.

A Problem with sim and offline mode on E75 like, The phone goes into an offline state and indicates "insert simcard". The screen goes white and flickers and the buttons gets unresponsive. Sometimes, but not always, then you will opted to restart the phone to an offline mode and manually go online.
This problem can be fix by firmware update.
