Connecting device via multiple carriers
摘要:
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.
