Can I complain if the courier arrives without SMS notification?

If there is no SMS notification when the courier arrives, you can complain, but you need to check the courier information first to confirm whether the courier has arrived. If the courier has arrived, but did not receive the SMS notification, it may be because the courier company or courier did not send the notification in time, or the mobile phone number is wrong. At this time, you can contact the courier company or courier to inquire about the specific situation and negotiate a solution.
