Abstract: A communication management system receives, from a first cellular network operator, a request for routing information associated with a first communication profile of a mobile device. The communication management system identifies, based on the first communication profile, a second communication profile that is an active communication profile for the mobile device, wherein the second communication profile is associated with a second cellular network operator. The communication management system determines routing information associated with the second communication profile. The communication management system sends, to the first cellular network operator, a reply comprising the routing information associated with the second communication profile.

Abstract: A communication management system receives, from a first cellular network operator, a request for routing information for a message that is addressed to a mobile device using a first communication profile. When the communication management system determines that the mobile device is connected to a second cellular network operator using a second communication profile, the communication management system responds to the request by: requesting, from the first cellular network operator, delivery of the message to the communication management system; receiving the message from the first cellular network operator; and sending the message to the second cellular network operator, where the message is addressed to the mobile device using the second communication profile.
