A method and system of detecting a delinquent mobile user device. An international mobile subscriber identity (IMSI) of a subscriber identity module (SIM) card of the user device is determined by the user device. The IMSI is sent to a Remote Recovery Server (RRS). A message is received from the RRS as to whether the IMSI is authorized for the user device. Upon determining that the IMSI is not authorized for the user device, a notification is displayed on a display of the user device.

A system and method including a downloadable application which forces to view targeted advertisements on their mobile device in order to gain access to use of the mobile device. The ads appear on a lock screen of the mobile device upon powering up or waking up of the mobile device. The user can take one of several actions with respect to the displayed ad and upon such action screen is unlocked and the user is provided with full function of the mobile device. The user can be incented for each action through the accumulation of points which can be used towards paying the user's phone bill or for receiving another reward.

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.

Disclosed is a method performed by an IP Multimedia System, IMS (140), of a communication network. The method comprises receiving information of a call initiation or a call reception by a wireless communication device (110), the information comprising an ID indicative of a subscriber of the wireless communication device (110). The method further comprises sending information of the initiated or received call to an online charging system, OCS (150), the information comprising the ID indicative of the subscriber of the wireless communication device (110), receiving, from the OCS (150) and in response to the sending, a pointer referring to a notification picture, and sending the pointer to the wireless communication device (110). Hereby it is possible for an operator to send notification pictures to its subscribers. Disclosed are also methods performed by the OCS (150) and the wireless communication device (110).

A method, a device, and a non-transitory storage medium are described in which a mapping table is transmitted to a user device. The mapping table includes, for each entry, an index, a frequency band, and wireless services available on the frequency band. Index information corresponding to a frequency band and wireless service available in a location associated with the user device is communicated to the user device. An icon associated with the wireless service is displayed on a display of the user device. A network device determines that the user device is using the wireless service to communicate via a wireless network and transmits, to a core network, an indication that the user device is using the wireless service on the frequency band.

A method and apparatus are provided for presenting multimedia content to a caller and/or a called party in association with a telephone call. Content may be presented pre-ring (before the called party's telephone rings), in-call, and/or post-call. Content presented to a party may be related to another party participating in the call or may be related to a third party (e.g., an advertiser that paid for the ability to have its content presented). Presented content may be actuable, to allow a caller to change the destination of a call, take advantage of an offer presented to him or her, redeem a coupon, schedule or queue a subsequent call, etc. To find a desired destination party, a caller may initiate a manual or automatic search of his or her local contacts (on his telephone) and/or a central or global directory or contact list.

A method for facilitating collection and display of information related to data usage by a plurality of mobile devices is disclosed. The method involves receiving first quantity information and sending a first identifier associated with the plurality of mobile devices and first activity-related information including the first quantity information to a server. The method also involves receiving group activity-related information associated with the plurality of mobile devices, the group activity-related information derived at least in part from second activity-related information including second quantity information, and producing signals for causing a display to display information derived from the group activity-related information. A method of associating a plurality of mobile devices in a group is also disclosed. Systems and computer-readable media for facilitating collection and display of information related to data usage by a plurality of mobile devices and for associating a plurality of mobile devices in a group are also disclosed.
