1. A method comprising:
- receiving, by a user device, an Internet Protocol address from a radio access network;
establishing, by the user device, a first connection with a first Internet Protocol multimedia subsystem (IMS) core of a first carrier network of a first carrier using the radio access network and the received Internet Protocol address, wherein the first carrier issues a first phone number used by the user device;
establishing, by the user device, a second connection with a second IMS core of a second carrier network of a second carrier using the radio access network, the received Internet Protocol address, and the first carrier network, wherein the second carrier issues a second phone number used by the user device;
receiving, by the user device, notification about a first call from the first carrier network;
determining, by the user device, whether, at a time when the notification is received, the user device is using the second carrier network for a second call; and
transmitting, by the user device, a busy message to the first carrier network when, at the time when the notification is received, the user device is using the second carrier network for the second call.

Abstract
A user device establishes a first connection with a first carrier network of a first carrier. The first carrier issues a first phone number used by the user device. The user device further establishes a second connection with a second carrier network of a second carrier. The second carrier issues a second phone number used by the user device. The user device receives a notification about a call from the first carrier network while connected to the first carrier network and the second carrier network.

9. A device comprising:
-
a circuit card to store an identifier associated with the device; and a processor configured to; generate authentication information based on the identifier; receive an Internet Protocol address from a radio access network; transmit the authentication information to a first carrier network using the radio access network and the received Internet Protocol address, wherein the first carrier network provides cellular phone service within a first geographic area, establish a first connection with an Internet protocol (IP) multimedia subsystem (IMS) core of the first carrier network after receiving a first confirmation, in response to the authentication information, from the first carrier network, transmit the authentication information to a second carrier network using the radio access network, the received Internet Protocol address, and the first carrier network, wherein the second carrier network provides cellular phone service within a second geographic area, and wherein the first geographic area is different from the second geographic area, and establish a second connection with an IMS core of the second carrier network after receiving a second confirmation, in response to the authentication information, from the second carrier network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. One or more non-transitory computer-readable media storing instructions executable by one or more processors of a computing device, the non-transitory computer-readable media storing one or more instructions for:
-
receiving an Internet Protocol address from a radio access network; establishing a first connection with a first Internet Protocol multimedia subsystem (IMS) core of a first carrier network of a first carrier using the radio access network and the received Internet Protocol address, wherein the first carrier network provides cellular phone service within a first geographic area; establishing a second connection with a second IMS core of a second carrier network of a second carrier using the radio access network, the received Internet Protocol address, and the first carrier network, wherein the second carrier network provides cellular phone service within a second geographic area, and where the first geographic area is different from the second geographic area; placing a first call, via the first carrier network and while located within the second geographic area, by using a first phone number associated with the first carrier network; and receiving, via the second carrier network and during an occurrence of the first call, a notification about a second call. - View Dependent Claims (18, 19, 20)
