The sim card is not defective.
Your a107 may not be working correctly.

Sim card error


If your phone gives you the sim card error, it means either the sim is not properly inserted, or the phone cannot read the sim card. Remove the sim and reinsert it back in the phone to see if it will work.

Try to use the sim in another phone, if it works, then it means your phone has been restricted to some certain sim cards and if it does not work on another phone, then it means the sim card is bad and the solution is for you to get a sim swap.

If the sim works on another phone, then you have to flash the phone with the appropriate software and cable in order for it to be able to work with any sim card.

Take care and good luck

When I switch On my phone it says "Sim card not valid". And its not taking the Sim Card. But without the sim card its perfect. My IMEI is 359849016183862. Please help me...

Hi, what might be the possible cause of the problem is either the Sim card your using on the phone or the Sim tray where the Sim card is inserted in the phone.

You can use the Sim card in another phone to be sure the Sim card is working properly.

After that, if the Sim card works,That means that Sim tray is damaged and will need to be replaced.

Have a nice day.

Nokia 6500 slide sim card registration problemit normally says sim card registration failed immediately i on it


There are two things causing this problem,either your phone is not registered to the Sim card's network or your Sim card is corrupt

To find out where the problem has come from,you should try another Sim with your phone, if the Sim does not work then the phone is registered to a particular network and no other Sim card will work on it.

If you try another Sim card and it works then your Sim card is corrupt and you should replace it.but to be double sure,test the Sim card on another phone to see if it works,if it does then your phone is not compatible with the Sim card's network but if it does not work then your Sim has to be changed
