Problems solved by technology

[0003] But at present, all mobile phones use a SIM card to match a SIM card number. When the user is out of town, it will add a lot of unnecessary roaming call charges to the mobile user. If you use a mobile phone with multiple cards, you need to choose the main SIM SIM card and auxiliary SIM card, the switching process is cumbersome, and it is difficult for mobile phones to change different communication networks at any time according to needs

Embodiment Construction

[0040] The present invention provides a method and a mobile terminal for realizing one card with multiple numbers for a mobile terminal. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The mobile phone number is determined by the SIM card and has nothing to do with the mobile phone itself. When a user applies for network access, the mobile communication company must first establish a contractual relationship with the user, that is, register the user's information in the relevant database, and at the same time provide the user with a SIM card, which is injected with IMSI (International Mobile Identity Number), Passwords, user access level con...

Abstract

The invention discloses a method for realizing mobile terminal one-card multiple-number and a mobile terminal. The method comprises the following steps: after the mobile terminal starts up, identifying legality and validity of each IMSI (international mobile subscriber identity) code in SIM (subscriber identity module) card by an operator network; when the identification succeeds, judging whether SIM card registration and authentication succeeds; when the identification fails, judging that SIM card number is it is illegal by the mobile terminal, and forbidding using the SIM card number; when the SIM card number registration and authentication succeeds is judged by the mobile terminal, opening the SIM card function; and if the SIM card number registration and authentication fails, returning a message that the SIM card communication fails, and closing the SIM card function. After the SIM card function is opened, the mobile terminal can dial and call in the telephone. By using the mobile terminal provided by the invention, the trouble that the user needs to change multiple cards in one mobile phone or one-phone multiple-card for call waiting is avoided, the great convenience is brought to the user, and the inspection effect of the user can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing one card and multiple numbers of a mobile terminal and the mobile terminal. Background technique [0002] With the rapid development of mobile communication technology, more and more mobile phones are used, the call quality is getting better and better, the price is getting lower and lower, and the coverage area is getting wider and wider. Some mobile companies have large network coverage and strong capabilities, but expensive calls; some have low call charges, but small network coverage. Therefore, users can choose different operators according to different needs. [0003] But at present, all mobile phones use a SIM card to match a SIM card number. When the user is out of town, it will add a lot of unnecessary roaming call charges to the mobile user. If you use a mobile phone with multiple cards, you need to choose the main SIM Card and auxil...
