Abstract: According to various embodiments, a user can receive voice calls using multiple phone numbers on a mobile device such as a smartphone. The voice calls can be carried via the wireless carrier associated with the mobile device, using the device's normal allowance for voice calls, without the need to use large amounts of data. In at least one embodiment, incoming voice calls are accurately identified as having been made to either the registered number for the device or an alternate number. In addition, in at least one embodiment, when a voice call is received at a device, the phone number, name, and/or other contact information for the originator of the call is/are provided to the user of the device. In at least one embodiment, any or all of these pieces of information can be provided to the user of the device for every incoming voice call.

Abstract: Limits are placed on the number of free and/or discounted communications (such as voice calls and text messages) available to a user, based on the number of communications received by the user. A user is given an allotment of credits, each worth one or more free and/or discounted communications. A credit balance is established and is continually adjusted as follows: it is increased whenever qualifying communications of a given type are received, and is decreased whenever free and/or discounted communications of the given type are initiated by the user. Once the credit balance has been depleted, the user may be blocked from initiating additional free or discounted communications, until the credit balance is increased. In at least one embodiment, different types of credits can be earned and/or used for different types of communications. In at least one embodiment, exchanges between the different types of credits may be permitted.
