Abstract: A method is provided for self-provisioning and personalization of a companion device. A primary user device receives input to initiate a cellular service activation process for a companion device, wherein the companion device includes a preloaded version of a service provider application for facilitating remote provisioning. The primary device provides, to the companion device, an updated version of the service provider application that replaces the preloaded version. The primary device receives, from the companion device, an embedded universal integrated circuit card (eUICC) identifier for the companion device and forwards the eUICC identifier to a network device and an identifier for the primary device.

Abstract: A method is provided for self-provisioning and personalization of a companion device. A primary user device receives, via an activation application for cellular service activation of a companion device, user input to initiate a cellular service activation process for the companion device. The primary user device establishes a local network connection with the companion device and receives from the companion device an embedded universal integrated circuit card (eUICC) identifier. The primary user device forwards, to a network device in a service provider network, the eUICC identifier along with an identifier for the primary user device. The primary user device receives, from the network device, an activation code for the eUICC and forwards to the companion device the activation code. The activation code automatically causes the companion device to initiate a profile download request for an eUICC to be included with a new line of service under a subscriber account associated with the primary user device.

Abstract: A system is configured to receive account information associated with a subscriber and a set of user devices, and receive user input, from a device associated with the subscriber, indicating that a feature is to be activated for the set of user devices. The device is configured to determine an association between the set of user devices and a feature code associated with the feature. The device is configured to receive a request to activate the feature from a user device, of the set of user devices, and determine that the user device is eligible to receive the feature based on the association between the set of user devices and the feature code. The device is configured to activate the feature for the user device based on determining that the user device is eligible to receive the feature.

Abstract: A device receives a message from a fixed user device associated with a first user. The first user is associated with a first mobile user device, and the message is destined for a second mobile user device associated with a second user. The device generates a first charge record for the first user based on the message and on a telephone number associated with the first mobile user device, and provides the first charge record to a billing system. The device generates a copy of the message, provides the copy of the message to the first mobile user device, and forwards the message toward the second mobile user device.

Abstract: A current supply includes a current mirror arrangement having a feedback circuit. The current supply includes a current mirror input stage connected to a constant current source providing a reference current; a current mirror output stage providing an output current substantially mirroring the reference current; and a feedback circuit feeding back to the current mirror input stage a feedback signal representing perturbations in the output current to cause the output current to more accurately mirror the reference current. In one embodiment, a dummy current mirror output stage substantially mirrors the reference current, and the feedback circuit receives a signal from the dummy current mirror output stage, and in response thereto, supplies the feedback signal to the current mirror input stage to cause the output current to more accurately mirror the reference current.
