Problems solved by technology

[0004] The traditional solution to SIM card loss is that the user restarts the mobile phone system. Although this process can completely solve the problem of SIM card loss, the solution first requires the user to be able to find out the situation of the SIM card loss, and then restart the mobile phone system. In order to solve the situation of SIM card loss, if the user does not find the situation of SIM card loss, the problem of SIM card loss will always exist, which may cause the user to miss some important information (such as important text messages, incoming calls, etc.)

Abstract

The invention discloses a mobile phone card losing recovery method and a mobile terminal applying a mobile phone card. The mobile phone card losing recovery method comprises the steps that when the mobile phone card is lost during normal working, voltages of the mobile phone card during normal working are continuously used for power-down and power-on treatment on the mobile phone card until the mobile phone card is recovered to normal working or the frequency reaches N; when the frequency of the power-down and power-on treatment carried out on the mobile phone card reaches N and the mobile phone card is not recovered to normal working, the power-down treatment is carried out on the mobile phone card; a timer is set and started, the first voltage and the second voltage are used for conducting the power-down and power-on treatment on the mobile phone card at set intervals until the mobile phone card is recovered to normal working. According to the technical scheme, automatic recovery of the mobile phone card can be achieved when the mobile phone card is lost.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a recovery method for a lost mobile phone card and a mobile terminal using the mobile phone card.
