NOTE There is the possibility of data loss while using the G3 SocketModem when streaming large amounts of data over the cellular connection and logging extremely large amounts of data to the serial debug port. Normal use cases will most likely not encounter this issue. If the issue is encountered, increasing the speed of the serial debug port to 115k baud, 230k baud, or higher will greatly reduce the risk of data loss.
