This section will guide you through the steps to select which SIM card to use when making a call on your iPhone 13. By the end of these steps, you’ll be able to seamlessly choose your preferred SIM card for each call.

Step 1: Open the Phone App

First, unlock your iPhone 13 and open the Phone app from the home screen.

The Phone app is where you can see your contacts, your call history, and access the dial pad. It’s the starting point for making any call.

Step 2: Dial the Number or Choose a Contact

Next, either dial the number you want to call or choose a contact from your list.

You can find your contacts by tapping on the Contacts tab at the bottom of the Phone app. If you’re manually dialing, just use the keypad.

After you’ve chosen a contact or dialed the number, you’ll see a call button appear. Do not press it just yet.

The call button is usually green and located at the bottom of the screen. It’s the gateway to making your call, but there’s one more step before you tap it.

Step 4: Choose the SIM Card

Now, look for an option that says "Primary", "Secondary", or shows the name of your SIM cards. Tap on it to choose the desired SIM card.

When you tap on this option, a list will appear showing your available SIM cards. Select the one you want to use for this call.

Step 5: Tap the Call Button Again

Finally, with the correct SIM card selected, tap the call button to place your call.

Your iPhone 13 will now use the selected SIM card to make the call. Congratulations, you’ve successfully chosen your SIM card!

After you’ve completed these steps, your call will proceed using the SIM card you selected. You can repeat these steps any time you need to choose a different SIM card for a call.
