1. A vehicle system, comprising:
- a controller in communication with at least two subscriber identity modules (SIMs), each of the SIMs providing network access via one of a plurality of preferred public land mobile networks (PLMNs) defined by a carrier associated with the SIM, wherein the carriers are not roaming partners with one another such that the preferred PLMNs defined by a first carrier are different from the preferred PLMNs defined by a second carrier, the controller programmed to,in response to detecting that signal quality of a connection to a first PLMN that is one of the preferred PLMNs of the first carrier is less than a threshold, connect to a second PLMN that is one of the preferred PLMNs of the second carrier selected from a list that combines the PLMNs of the SIMs.

Abstract
A vehicle carrier swap system includes a controller that, in response to a notification indicating first public land mobile network (PLMN) access signal quality is less than a threshold and successful registration with a second PLMN selected from a set of PLMNs made available by at least two subscriber identity modules associated with non-roaming partner carriers according to a priority defined by the carriers, provides network access using the second PLMN.

10. A method for a vehicle, comprising:
responsive to detecting, by a controller, signal quality of a first public land mobile network (PLMN) connection less than a threshold, connecting to a second PLMN selected from a prioritized list combining preferred PLMNs of at least two subscriber identity modules (SIMs), wherein the respective preferred PLMNs are different as defined by carriers that are not roaming partners with one another, and providing network access using the second PLMN. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A vehicle carrier swap system, comprising:
a controller connected to at least two subscriber identity modules (SIMs), each of the SIMs providing network access using one of a plurality of preferred public land mobile networks (PLMNs) defined by a carrier of the SIM, wherein the carriers are not roaming partners with one another such that the respective preferred PLMNs are different from each other, the controller programmed to, in response to detecting that signal quality of a current network connection to a first PLMN is less than a threshold, select a second PLMN from a prioritized list that combines the respective preferred PLMNs of the SIMs, wherein the first PLMN is one of the PLMNs of a first carrier and the second PLMN is one of the PLMNs of a second carrier, initiate registration with the second PLMN, and upon registration, connect to the second PLMN. - View Dependent Claims (18)
