The invention discloses a text message display method and a mobile terminal. The method is performed as follows. When the mobile terminal receives a targeted text message, the mobile terminal determines if any character string in the text message satisfies pre-set rules. If so, the mobile terminal outputs a text message display frame containing the targeted text message, and the text message display frame is displayed in a floating manner on the currently running interface. The currently running interface is used to input the character string which satisfies pre-set rules. When the mobile terminal detects that inputting action is performed on the currently running interface, the mobile terminal keeps the text message display frame displayed on the currently running interface in a floating manner. Therefore, it is noted that when recognizing a verification code text message, the mobile terminal can display the verification code text message in a floating manner on the currently running interface in the form of the text message display frame. A user can therefore operate the currently running interface because the text message display frame is kept always at a display state. In this manner, a user can effectively input correct confirming code, thereby improving user experience.
