Exemplarily, referring to fig. 2, by extending a first preset file in a SIM card to store setting information of a call forwarding unconditional service CFU set in a user space, when a user terminal is initially started by installing the SIM card, a state of an additional service supporting a Voice over Long-Term Evolution (VOLTE) Voice bearer is obtained through a network, and a service in the user space is read through the extended first preset file CFISurl. Specifically, the method includes the steps of firstly reading related file information of a user space in the SIM card, determining that the CFISurl exists in a first preset file after related services in a service list are started according to the related file information, and accordingly reading a state value of an indicator of unconditional call forwarding in the first preset file, so that state setting information of a current unconditional call forwarding service CFU of the SIM card can be directly obtained according to the state value of the indicator, the state setting information does not need to be obtained through a network, and the state of the CFU can be quickly obtained after a user terminal is started. Especially, under the condition that the initial startup is not networked, the state of the CFU is quickly acquired, and the configuration efficiency of the SIM card is improved.
It should be noted that the setting information of the unconditional call forwarding service CFU stored in the first preset file in the SIM card includes service setting status, format and number information, so as to facilitate the storage of the URL format number by fast eating of the first preset file.
