Wireless mobile device functionality can be added to radio devices via a hardware device that comprises wireless network access. Alternatively, radio device functionality can be shared with a wireless mobile device or the hardware device. The functionalities of either device can be shared via a physical or wireless connection. For example, a microphone device comprising a display screen and long-term evolution (LTE) functionality can be connected to a radio device to facilitate LTE functionality for the radio device. Thus, a user of the radio device can utilize the display screen of the microphone device to send text data, which could not previously be sent by the radio device, over the wireless network via the microphone device.
