The invention provides a communication method and device.In one implementation mode, the communication mode is applied to a universal integrated circuit card, the universal integrated circuit card is configured with a user permanent identifier and a pseudo identifier corresponding to the user permanent identifier, and the method comprises the steps that the universal integrated circuit card generates a user hidden identifier according to the pseudo identifier, wherein the length of the user name contained in the pseudo identifier is different from the length of the user name contained in the user permanent identifier, and the length of the user name contained in the pseudo identifier is larger than a first threshold value and smaller than a second threshold value, and then the universal integrated circuit card sends the user hidden identifier to the mobile device. Through the scheme, the privacy security of the user can be improved. 本申请提供了一种通信方法和装置，其中，在一种实现方式中，该通信方式应用于通用集成电路卡，通用集成电路卡配置有用户永久标识以及该用户永久标识对应的伪标识，该
