Methods, systems, and computer-readable media for receiving, by a removable computing device that is electrically connected to a computing system through a physical connection, contact information from a contact list that is assigned to a user account. The user account is associated with a mobile computing device that is in wireless communication with the removable computing device. The removable computing device is configured to physically disconnect from the computing system. The removable computing device provides the computing system with the contact information for presentation by a display of the computing system. The removable computing device receives from the computing system an indication of user input requesting that the mobile computing device initiate communication with a device identified by the contact information. The removable computing device transmits data to the mobile computing device that causes the mobile computing device to initiate the communication with the device identified by the contact information.
