If you have an iPhone, there are a few ways to delete messages from both the left and right side of the device.

  1. Open the Messages app and select the “Delete” button at the top.
  2. Type “delete” in the text field and press Delete.
  3. If you have multiple messages on your left side, they will be deleted one after the other, but if you have multiple messages on your right side, they will all be deleted at once.
