Apple's mobile phone uses the main card to make calls. Why is the secondary card not on the card?

1, hello, there is no service on Apple's mobile phone. First of all, I suggest you enter Mijing 06 on the dialing page to see if there is any serial code on your mobile phone. If there is a string code on the mobile phone, it means that it is a card or a card holder problem.

2. The SIM card without service is not put into the card slot correctly, so the user can re-insert the SIM card. The SIM card without service is damaged. Check the gold card area of the SIM card for obvious damage or scratches. If it is damaged, it can only be replaced.

In this case, another card will be affected during the call, so there will be no network.
