How to set up and close a dual card of Apple mobile phone?

On 20 18, Apple introduced the dual-card dual standby function, allowing users to use two SIM cards at the same time. But sometimes we may only need to use one of the cards, so how to set it up? It will be introduced in detail below.

Step 1: Enter "Settings"

First, we need to enter the "Settings" interface of the mobile phone. You can find the "Settings" icon on the home screen or through the search function.

Step 2: Select "Cellular Mobile Data"

In the "Settings" interface, we need to select the "Cellular Mobile Data" option. This option allows us to control which SIM card the mobile phone uses to surf the Internet.

Step 3: Close the card that needs to be closed.

In the "Cellular Mobile Data" option, we can see the switches of two SIM cards. If you want to close one of the cards, just turn off its switch. In this way, only one card can be used without affecting the use of another card.

It should be noted that after a card is closed, cellular mobile data and SMS functions will not be available. If you need to re-enable this card, just go back to the Cellular Data option and turn on its switch.

The above is the detailed steps of how to set the dual card of Apple mobile phone to close one card. If necessary, you can follow the above steps.
