  • Methods for initiating operating voltages for subscriber identity cards and systems utilizing the same
    Patent number: 8208961
    Abstract: A system for operating at least two subscriber identity cards has a subscriber identity module (SIM) controller generating a first voltage variable signal with a first voltage level to a first subscriber identity card during a first time period, generating the first voltage variable signal at a second voltage level to the first subscriber identity card during a second time period, receiving a first code indicating that generated voltage matches from the first subscriber identity card during the first or second time period, generating a first operating voltage with the first voltage level to the first subscriber identity card when receiving the first code in the first time period, generating the first operating voltage with the second voltage level when receiving the first code in the second time period.
    Type: Grant

  • Methods for initiating operating voltages for subscriber identity cards and systems utilizing the same
    Patent number: 8121643
    Abstract: A system for initiating operating voltages for subscriber identity cards is provided. The system includes a first subscriber identity card, a second subscriber identity card, an RF module, a controller and a Baseband unit. The controller initiates a first operating voltage of the first subscriber identity card and initiates a second operating voltage of the second subscriber identity, respectively. The Baseband unit cooperates with the first subscriber identity card to camp on a first cell and cooperates with the second subscriber identity card to camp on a second cell via the RF module.
