Abstract

The present invention discloses a wireless communication device with an SIM-to-SD adaptor. An adaptor card is disclosed that allows a wireless communication device to access and communicate with a SIM card trough an SDIO terminal accessibly located at an exterior of the device. The adaptor card includes a SIM receiving terminal configured to receive a SIM card. The SIM receiving terminal includes a SIM interface that contacts the plurality of pins located on the SIM card in order to communicate with an IC chip located on the SIM card. The adaptor card further includes a signal conversion module that converts signals between a SIM protocol for signals transmitted to, or received from, the SIM card, and an SD protocol for signals transmitted to, or received from, the electronics device. The signal conversion module is also configured to map the signals received at the terminals of the adaptor card to the corresponding terminals of the SIM card.

Description

technical field [0001] The present invention relates to wireless communication devices, and more particularly, to wireless communication devices that enable easy access and removal of SIM cards. Background technique [0002] Wireless communication devices, such as cellular telephones to provide an example, are becoming more and more common in both personal and business environments. Wireless communication devices provide users with access to a variety of information. For example, users can surf the web through a web browser on the device, download small application programs (such as "apps") from digital marketplaces, send and receive email, or make phone calls using Voice over Internet Protocol (VoIP). Thus, wireless communication devices provide users with great mobility while keeping users "connected" to communication channels and information. [0003] A wireless communication device communicates with one or more wireless access points to send and receive data. Typicall...
