Inexplicably received a hotel check-in SMS registration.

Someone should have written your mobile phone number on the contact number when placing an order.

See if you have booked a hotel or air ticket with anyone before. If yes, ask the other party if they didn't change that contact when they made a reservation for someone else.

The specific process of staying in the hotel: you can make a reservation online or by phone, or you can go directly to the hotel and open it now. After arriving at the hotel, go to the front desk to communicate with the waiter, choose the room you need, then take the ID card registration information and pay the deposit. Holding a room key or room card, someone will usually guide you to the room. After checking into the room, make sure that the items in the room are free and need to be consumed. Generally, people who need to spend will have a price tag. At the same time, take care of your important things, take your room card and don't lose it. If you need to save time before checking out, you can call the front desk to tell you to check out. At this time, a waiter will clean the room and then go directly to the front desk to pay the bill. The check-out time of the hotel is usually noon the next day 12, and some members and the like also check out at 2 pm.
