Problems solved by technology
Since the SIM card is pluggable, at present, the SIM card and the mobile terminal are mostly connected by a shrapnel structure. During the use of the mobile terminal, if the mobile terminal encounters vibration, drop, or other reasons, it may cause the SIM card to be disconnected from the mobile terminal. The shrapnel contacted by the card is temporarily disconnected, and the normal communication of the SIM card will be interrupted at this time, because the interruption time is often very short and difficult to be noticed by the user; but if this interruption accumulates over time, it will definitely affect the performance of the mobile terminal
[0004] On the other hand, when the mobile terminal is sent for repair due to various failures, the information about the abnormal interruption of the SIM card communication is very important for the user, the mobile terminal maintenance point and the operator, but there is no good SIM card in the prior art.

The invention discloses a mobile terminal and a SIM card hard losing recording method based on the mobile terminal. The SIM card hard losing recording method based on the mobile terminal comprises the following steps: setting a first counter in the memory of the mobile terminal, reading the value of the first counter while a SIM card is inserted into the mobile terminal, and adding 1 to the value of the first counter and writing back into the memory; reading the the first counter while the mobile terminal detects that the SIM card is pulled out, and subtracting 1 form the value of the first counter and writing back into the memory; and reading the first counter in the memory while the mobile terminal is in the state that the SIM card is inserted in the mobile terminal, and obtaining the SIM card losing times by subtracting 1 form the value of the first counter. By means of the invention, the abnormal losing times of the SIM card can be detected and recorded to ensure the stable operation of the system, and the record of abnormal losing times of the SIM card can be given while the mobile terminal is sent for maintenance due to various fault, therefore, the SIM card hard losing recording method based on the mobile terminal can provide assistance for fault analysis of the mobile terminal maintenance points.
Description
technical field [0001] The invention relates to the field of mobile terminals, in particular to a mobile terminal and a mobile terminal-based SIM card hard-off recording method. Background technique [0002] SIM (subscriber identification module, customer identification module) card is also called subscriber identification card, and it must be equipped with a SIM card in a mobile phone to make a call. [0003] At present, most mobile terminals adopt a pluggable SIM card design, that is, the SIM card of the mobile terminal is replaceable, and the user can replace the SIM card by himself. Since the SIM card is pluggable, at present, the SIM card and the mobile terminal are mostly connected by a shrapnel structure. During the use of the mobile terminal, if the mobile terminal encounters vibration, drop, or other reasons, it may cause the SIM card to be disconnected from the mobile terminal. The shrapnel contacted by the card is temporarily disconnected, and the normal communic...
