If you don't escape from prison, you can only enter the SMS sending interface. On the right side of the contact bar, click the "+"button to add contacts one by one, and then send them in groups. To escape from prison, install the KuaiDial plug-in and enter the settings menu of iPhone. You can see that the option of speed dial appears. Select "SMS". Open the slider after "Batch Add Function is on by default". Pay special attention here. After setting, the Home button will exit the desktop, then double-click the HOME button to open the multi-task list, long press the setting icon, and click the red minus sign to close. Otherwise, the changes just made may not take effect.

Enter the SMS sending interface and click the plus sign behind the recipient.

It can be found that in the interface of selecting contacts, clicking a person will be followed by a check mark. You can select any number of contacts at a time. Please note that clicking Cancel above will complete this selection, but it will not cancel the contact you selected this time. So it's solved.
