This video was a quick review of the Voom Internet Service aboard Royal Caribbean’s Oasis of the Seas. Overall I would call the Internet usable but not “amazing”. It’s expensive but given no other option, I would deff take it, works for most things. Also make sure that you get the stream and surf package otherwise you won’t be able to watch video content or iMessage/text videos. If you have a compatible phone and/or carrier make sure you turn on Wi-Fi calling which will enable “cellular like” features while at sea.
