You will be able to find your way. ViewRanger doesn't need a phone signal (eg. EE, O2, etc.) to work - it uses your phone's GPS and satellites. Switching your mobile data and wifi off, just leaving the location/GPS active will save battery life too.
However, to use buddy beacon on it you DO need a phone signal (eg. EE, O2, etc.) so that might be an issue in more remote places.
