Thanks for responding. Just to be fair, the Holland America web site describes the Surf Package (Included with HIA) as being for web surfing and emails and does state that audio/video features in messaging apps are not supported, so the fact that video and streaming calls were impossible is not really surprising. The Premium Package states that it is fast enough for audio and video streaming.
