The invention relates to a terminal operation control method and device. The method comprises the following steps: receiving an operation instruction on a terminal when the terminal is in a standby state; judging whether the operation instruction belongs to a preset communication operation instruction or not, wherein the preset communication operation instruction includes an operation instruction for communicating with outside; and forbidding to perform the operation instruction when the operation instruction belongs to the preset communication operation instruction. By means of the technical scheme, operations against intentions of users themselves that the terminal dials a number automatically or by other people or sends a messy code short message and the like when the terminal is standby can be avoided; incorrect operations of the terminal can be reduced; the use safety and reliability of the terminal are increased; and the user experience is good.
