What is the Apple 10 echo button?

For Apple's SMS echo effect, there is no charge as long as it is connected to the network, but the other party needs to turn on the iMessage function and connect to the network.

If your iPhone will be charged inexplicably, it is basically because you have not turned off the automatic renewal of some subscription types of apps. The solution we want to solve is also very simple, just cancel those packages that will automatically deduct fees.

There are five steps to cancel automatic deduction.

1. First, click "Settings" on the desktop to enter and select the options in the red box.

2. After entering, find the column of "AppleID" and click Enter.

3. After entering, select the "View AppleID" option.

4. Then find the item "Subscribe" and click enter.

5. After entering, find the item to unsubscribe, and click unsubscribe to close the automatic renewal.
