Iphone selects the secondary card to send SMS.

After setting the dual card, the default setting is usually the main number for sending SMS. If you want to use the secondary card to send short messages, you need to manually switch between the primary card and the secondary card. Here's how to use the secondary card to send messages.

How does Apple xsmax send text messages with a secondary card?

1. After returning to the desktop of your mobile phone, find and click the dial icon.

2. Click Address Book in the bottom menu bar.

3. Then find the contact you want to call, such as "ba", and click on the contact.

4. After entering the contact details page, click the main number under the contact name, as shown.

5. Then we can see the options of primary number and secondary number in the mobile phone, click the secondary number and then select Done, and then select a short message to send to the contact.

Note: The next time you want to send a text message with the main number, you still have to repeat the above steps and set it as the main number, which is still troublesome. It would be very convenient if you can set a primary card or a secondary card for a single contact. At present, there is no such function, which is still a pity.
