Under what circumstances does SMS reply prompt your hotel order?

There are two situations. In the first case, you have registered your mobile phone number on the platform before or booked a plane ticket and hotel with this mobile phone number, so he sent you corresponding advertisements and preferential information.

The second is your mobile phone number, which was used by the previous owner when booking air tickets and hotels on the platform, but the latter number was not changed when it was not used, so his information will be sent to the number she used every time she booked air tickets and hotels, but you are using this number now, so you will receive relevant information.
