A process for authorizing wireless service includes providing a generally rectangular flat form factor card having a first surface and opposing second surface. The process further includes providing a machine-readable activation code arranged on the first surface, wherein the machine-readable activation code is configured to authorize the wireless service when provided to a system associated with a wireless service provider, receiving the machine-readable activation code in a server, the machine-readable activation code being captured by a wireless device, and provisioning the wireless service to the wireless device from a wireless network when the machine-readable activation code is provided to the system associated with the wireless network.

A card reader includes a digital connector such as a Universal Serial Bus (USB) plug or an Apple® Lightning® plug. The digital connector includes a corresponding connector interface, which provides voltage to at least a card reader interface and an integrated circuit (IC) of the card reader. The card reader interface outputs an analog transaction information signal upon reading the card. The IC generates a digital version of the analog transaction information signal, encrypts the digital version, converts that into an analog audio signal. The audio signal can then be sent to the connector interface, which converts it into a digital signal such as a USB or Apple® Lightning® signal that is sent by the digital connector to a mobile device. Alternately, the audio signal can be sent to a microcontroller that converts the audio signal to a digital format such as USB, and then to the digital connector.

The present invention provides implementation and communication methods, an apparatus and a system of a virtual subscriber identity module. The implementation method includes: receiving a VSIM application request sent by a terminal, where the VSIM application request carries an identifier of a VSIM desired by the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, so that the terminal installs the VSIM according to the VSIM installation information. The embodiments of the present invention effectively solve a problem where an existing mobile operator network does not support the VSIM, and provide an effective and convenient operation scheme for an existing domestic or international roaming service.

An electronic device and method are disclosed herein. The electronic device includes a communication module, a display, a memory and a processor which implements the method. The method includes receiving access point (AP) information from at least one AP through the communication module, generating an AP list including an AP communicatively connectable with the electronic device based on the received AP information, storing the AP list in the memory, identifying a state of the electronic device, determining an arrangement criterion for arranging a display order of Aps included in the AP list based on state information about the electronic device, and controlling the display to arrange the AP list according to the determined arrangement criterion.

Methods, devices, and servers for as-needed update of a trusted list are provided herein. An electronic subscriber identity module (eSIM) server receives a request for an eSIM of a particular type from a wireless device. The eSIM server evaluates the particular type and requests an eSIM of the particular type from a second eSIM server, which is not initially trusted by a secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device. The wireless device passes the policy update to the SE, for example, a universal integrated circuit card (UICC). The UICC updates the trusted list with an identity of the second eSIM server. When the wireless device downloads a bound profile package (BPP) containing an eSIM from the second eSIM server, the UICC validates the BPP based on the updated trusted list. The eSIM is then installed on the UICC.

In a signal transmission system for transmitting an analog signal, in which a billing signal is superposed on an audio signal, from a transmitting device to a receiving device, the transmitting device includes a separation unit configured to separate the audio signal from the analog signal, an AD conversion unit configured to perform AD conversion on the audio signal separated by the separation unit, a detection unit configured to detect the billing signal from the analog signal, a coding unit configured to encode the billing signal detected by the detection unit, and a transmission unit configured to transmit the audio signal subjected to the AD conversion by the AD conversion unit and the billing signal encoded by the coding unit to the receiving device, and the receiving device includes a reception unit configured to receive the audio signal and the billing signal transmitted by the transmission unit, a DA conversion unit configured to perform DA conversion on the audio signal received by the reception unit, a decoding unit configured to decode the billing signal received by the reception unit, a conversion unit configured to convert the billing signal decoded by the decoding unit into an analog wave, and a combination unit configured to combine the audio signal subjected to the DA conversion by the DA conversion unit and the analog wave.
