Abstract

An embodiment of the invention discloses a file reading method and device. The method comprises the following steps: reading necessary file information in a subscriber identity module (SIM) card in a terminal device; judging whether a target elementary file (EF) in the necessary file information is read successfully; and if judging that the target elementary file (EF) in the necessary file information is read unsuccessfully, skipping reading the target EF and finding and reading a file corresponding to the target EF in the terminal device. The file reading method and device solve the problems of failure of identification of the SIM card or failure of network registration and the like due to reading failure of the target EF, thereby improving network access efficiency of the SIM card, and improving user experience.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a file reading method and device. Background technique [0002] The mobile phone and the SIM card together constitute the mobile communication terminal equipment. Whether it is a GSM system or a CDMA system, a digital mobile phone user will get a SIM card (Subscriber Identity Module) or UIM card (User Identity Module) when "connecting to the network". The SIM card is a "smart card" that conforms to the GSM standard, and can be inserted into any mobile phone that conforms to the GSM standard to realize the "function that the phone number is not random with the card", and the call fee is automatically included in the bill of the card holder on, nothing to do with the phone. [0003] In the prior art, the user must successfully identify the SIM card through the terminal equipment to perform normal calls and Internet services through the terminal equipment. However, the inabili...
