Probably could improve the signal using a mifi with good external antennas in the antenna ports, mounted to balcony railing. I also tend to use a bit of cellular data on sailaway or arrival, depending on the ship's satellite system, congestion, and bandwidth. Celebrity upgraded most of the Solstice class satellite systems and RCCL's Quantum class is also fairly modern (though Celebrity charges a whole lot more :/ ) I can usually latch onto a network in port and keep on using it for ~ 20 min upon sailaway while most people are hogging the ship's wifi because their phones didn't have signal in port/afraid of data overages. After that, the ship's wifi is less congested around dinner time while people are dining and late at night.

A VPN subscription is < $10 a month to secure your browsing on public wifi networks. It can also help to have VPN to position yourself "local to home" for online banking or downloading a show via Netflix/Prime for offline viewing.
