A:AnswerHi Loreley. Excellent question. No, communication features do not require a WiFi connection - just an active Ace Pass data plan. If you need help or have more questions please contact us here: https://support.google.com/fitbitacelte/gethelp
A:AnswerHi, there. The Fitbit Ace LTE is water resistant and splash proof. It is designed to withstand the pressure exerted by 50 meters (5 ATM) of water. The watch is designed to comply with a water protection rating of 5 ATM under ISO standard 22810:2010 when each device leaves the factory, but it is not waterproof or dust proof.
