Problems solved by technology

Therefore, when consumers need to switch from network A to network B, that is, jump to the identification card service, they must turn off the power first, and then turn it on again within ten seconds, because the voltage change will force the current to jump to another One SIM card can achieve the purpose of changing the card number, but this way of installing on the battery may cause excessive power consumption and easy to wear the surface of the SIM card, and it is quite inconvenient during the switching process
[0004] Therefore, when mobile phone users need to use dual cards, the current technology will cause trouble in use
In addition, existing dual-card mobile phones on the market are only limited to switching, or transferring calls to an unregistered SIM card to a registered SIM card, but cannot enter the unregistered SIM card, let alone the phonebook in the SIM card. , Short Message Service (Short Message Service, hereinafter referred to as SMS) and other data to edit, modify and send related operations

Abstract

A method using the microprocessor control unit (MCU) in mobile phones to switch data in two user ID cards includes following steps. Two user's ID cards provided are installed in two ID card slots in the mobile phone. Using one user's ID card logs on the communication network with the setting of the mobile phone. The command for transferring the data of the user's ID card is inputted. With the command being received, the MCU transfers the data on the ID card unregistered to the ID card already registered. Final step logs on the communication network of the user's ID card. The selected ID card is registered in the state set before. Another unregistered user's ID card is initialized.

Description

technical field [0001] The invention relates to a dual-card switching method of a mobile phone, in particular to a method for intelligent dual-card switching of SIM cards of a mobile phone. Background technique [0002] At present, users who use the Global System for Mobile communication (Global System for Mobile; GSM) can obtain network services only after inserting a Subscriber Identification Module Card (SIM card for short) into the mobile phone. Through the SIM card, the user can become a registered user of the network and enjoy various services provided by the network. Most of the mobile phones currently on the market have a single SIM card, but many people have more than one SIM card, and often need to change the SIM card before they can be used, which is quite inconvenient. [0003] Along with domestic mobile phone user number constantly increases, popularization rate is also more and more higher, and the people that a user has the SIM card of more than two portable ...
