I have never downloaded the same journey, and I can always receive a booking message.

Does the subject want to ask, "What is the message that you can always receive a reservation without downloading the same itinerary?" Personal information was leaked, and some people used their identity information to buy tickets. When you check the SMS, you can receive the reservation SMS at any time without downloading the same itinerary. This is caused by personal information being leaked and being bought by others with their own identity information. You need to take good care of your personal information and raise your safety awareness.
