I want to edit a reminder message but don’t know how? The guest has booked a room with us, and then we need to send him a check-in reminder text message.

Warm reminder from ×× hotel/guesthouse: Mr. ×/Miss ×: Hello! If you reserve room × on × month × day at × hotel/guesthouse on × month × day, you can check in tomorrow. If you have other arrangements, you can cancel the reservation by replying to a text message or calling us. Thank you for your cooperation and wish you a happy life. !
