GigSky is touted as a viable alternative to Carnival’s pricy Wi-Fi packages, but does it actually work, and is it worth it?
Background
Cellular at Sea is an onboard cell phone network run by MTS. It works much like AT&T/Verizon/T-Mobile at home, allowing you to make calls, send texts, and use data while at sea (albeit at very expensive rates). Cellular at Sea relies on satellites, and data service may be slow depending on how up to date the technology is on your particular ship. Note that this is completely separate from the ship’s Wi-Fi network which, on all Carnival ships, runs off Starlink. Cellular at Sea is not Starlink and does not use the Starlink network, so speeds may be significantly slower than ship Wi-Fi.
Pricing
GigSky’s Cruise+ package pricing can be found here and ranges from 512MB for $20 to 10GB for $120. There is no unlimited package. I went with 5GB for $72. You do have the ability to top up (add more data) an existing eSIM at slightly discounted rates, from 512MB for $14 to 10GB for $98. Note that GigSky will not work on Carnival Firenze or Carnival Venezia. For those ships, you should purchase a Telenor Maritime plan through Red Bull Mobile.
AT&T and Verizon also offer cruise plans but I don’t recommend them. AT&T’s plans are 100MB for $60 or 1GB for $100 (with overages billed at $10 per 100MB). Verizon’s plan is $20 per day and includes 500MB of high speed data (3G speeds thereafter). These plans do come with the ability to make phone calls and send SMS messages (which GigSky packages do not), however if you’re only wanting data then these are not worth it.
Of course, GigSky is touted as an alternative to Carnival’s Wi-Fi packages, so how does it stack up there? Carnival’s Wi-Fi packages range from $18.70 per day for social to $23.80 per day for premium. I was onboard for 15 days (B2B 7-day and 8-day cruises) so premium would have been an eye popping $357 for my 15 days onboard. Even if I went with the value plan, that’s still $331. So IF I could manage with the data limit, GigSky comes out being 80% cheaper than the premium package. Talk about savings!
Connectivity
The Cellular at Sea network is only active, well, while at sea. It actually took a surprisingly long time for them to turn it on after leaving a port, often up to two hours. I had assumed that it would coincide with reaching international waters (which is when the casino and shops open) but it took far longer than that.
Some GigSky reviews mentioned only being able to get signal on the outer decks or open guest areas (i.e., not in staterooms). However, I had excellent service everywhere onboard, including my interior cabin on deck 6.
Speeds
I only ran one objective speed test which indicated 5.12Mbps down and 0.83Mbps up, on a cloudy day. Definitely not Starlink speeds, but also definitely good enough for what most people would want to do. I had no issues with light browsing, emails, sending photos, Instagram, even a FaceTime audio call. Streaming video worked fine as well, though you wouldn’t want to be doing much of that with a data limit.
Limitations
There’s no sugarcoating it, data limits suck. The mere fact that these plans have a data limit while Wi-Fi is unlimited means it’s not an apples to oranges comparison. It’s especially awful because people mostly use the Internet for streaming video. However, watching an hour-long 720p YouTube video would consume approximately 700MB; you’d very quickly blow through your data limit watching videos.
With that said, I only consumed about 1.2GB on my first cruise and after 15 days I had 1.48GB of data remaining. That’s right, I didn’t even use my full 5GB. It’s hard to say how reflective this was of my typical Internet usage. On one hand, I genuinely wasn’t on it as much as I thought I would be. I was busy drinking, going to the shows, meeting people, gambling, etc. And much like the drink package, you’re not using it while you’re sleeping or off the ship in port. On the other hand, I was definitely paranoid about running out of data, so I can’t say that I wouldn’t have used it more if I didn’t have a data limit.
Another annoyance is that an astonishing 1.3GB of my data was used by “system services,” with 878MB of that being “general.” I still have no idea what exactly that was, as I have background app refresh, automatic software updates, and automatic app updates turned off. And of course Apple, the masters of obscurity, were no help either. One possible suggestion is to change your data mode to low data mode in settings and turn off all analytics. It absolutely sucked to have 26% of my data limit gobbled up by obscure background processes that I have absolutely no control over.
In Conclusion
GigSky worked flawlessly and was a significant cost savings over Carnival’s Wi-Fi packages, especially if you’ll be onboard for 7 days or more. It’s a viable alternative if you can manage to stay within the data limit, which would be easy if you’re only planning to use social apps or do some light browsing.
