We were on NCL in January and they had an app that had a text communication portion. It seemed to only wr]k with IPhones. It was also a bit spotty. Not always working.
Is the Celebrity app the same? It states "Remember to connect to the ship's Guest Wi-Fi once onboard to use all of the app's features, chat with family and friends,..."
Is the ships Guest WiFi free for all or do you need to purchase a wifi plan?
Is it for all types of phones?
Is the text communications good?
