It's normal to go to beautiful places without internet connectivity, walking or running for a few day and any Garmin watch should be able to connect to the APP "Garmin Connect" by Bluetooth to see the statistics of these activities without showing plenty of errors due to the lack of network connectivity. It's too frustrating to see the application doesn't work in these places.
Without connectivity, It should be ready to synchronize with the "Garmin connect" keeping the information locally at the memory of the smart phone, just showing only one message to explain the limitations of the "offline mode".
