Card error, Sim Cards in Decline, Simcard Rejected

This time I will give you a few tips to repair the damage Simcard on all phones, because it is basically the same damage, hopefully these tips can be useful
All this damage is marked with error notification as mentioned above appears on the display. These signs appear when we insert the SIM card into the phone and of course the phone will not work, because the phone is not able to read all the data information contained in the SIM Card including the number that will be used. What causes this problem occur?
There are various factors that may cause problems associated with the SIM Card and not necessarily those problems caused by the SIM Card, among other factors, namely:· Problems Software error or locks (Operating System mobile phone SIM card was not able to read because of system errors in it)
· SIM card damaged (damage is caused by a damaged SIM card so it can not be read by mobile phone)
· Connector connects the SIM card is bad
· Simcard damaged connector (As a means of determining connectivity between mobile phones and SIM Card connector is a major determinant cause of damage)
· Driver support is broken (diode, capacitor, resistor and transistor)
· Filter damaged SIM Card
· IC Power Problems
· CPU Problems
· Disconnect the SIM card route
The steps that must be done to overcome the problems associated with the SIM Card, among others, namely:
· Check simcard with simcard new way to try to (try to pair, if functioning properly, the damage is not happening on the phone but the SIM Card)
· Check sim card connector is damaged or there is bad conn (check the legs of the connector and fix it or clean it carefully)
· Check point (with the understanding the scheme simcard lane and take the measurement using a multi tester x 1ohm or use the buzzer on multitester)
• Use the software to unlock simlock or flashing do in case of data errors (software used by, among others, Tornado, Griffin, JAF, Prodigy and other software improvements)
• If there is a problem in the driver re-do the solder or replacement of the resistors, capacitors, diodes or transistors associated with the SIM Card (see scheme phone line)
· Apply solder to the IC power or re-do the replacement
· Perform solder re-do on the CPU or replacement
