Best eSIM for a Royal Caribbean cruise

VOOM WiFi is fast but priced per day. Here's how to stay connected on RCL ships and in port for less — and the one eSIM that works at sea.

The quick answer

Two eSIMs cover your whole RCL voyage

Royal Caribbean sells VOOM, one of the better cruise WiFi products — but it's still charged per day, per device. The cheaper route for most cruisers is a maritime GigSky pass for sea days, plus a cheap local/regional eSIM for port days. Buy both before you board and you'll rarely need to pay VOOM's full daily rate.

Royal Caribbean eSIM questions

Does GigSky work on Royal Caribbean ships?
Yes. GigSky's maritime coverage spans 290+ vessels including Royal Caribbean's fleet, so it can connect via the ship's onboard cellular system while you're sailing. As always, install it before you board and toggle it on when you want at-sea data.
Is an eSIM cheaper than Royal Caribbean's VOOM WiFi?
For light to moderate use, usually yes. VOOM Surf & Stream is convenient but priced per day per device. A cheap in-port eSIM covers shore days for a few dollars, and a GigSky at-sea pass handles sailing days — often cheaper overall than VOOM for the whole cruise. Heavy streamers may still prefer VOOM's premium tier. We run the maths in our WiFi vs eSIM cost guide.
Which eSIM should I use in Royal Caribbean's Caribbean ports?
Caribbean coverage is more island-by-island than Europe, so a broad regional plan from Airalo or a budget option like aloSIM works well. See our dedicated Caribbean cruise eSIM guide for the per-island detail.
What about Royal Caribbean's private island (Perfect Day at CocoCay)?
CocoCay is a Royal Caribbean private destination with its own WiFi; a land eSIM there is hit-or-miss. Most guests just use the ship/island WiFi for the day and rely on their port eSIM at regular island stops. For sailing between stops, you're back to a GigSky at-sea pass.
Do I still need GigSky if I'm buying a port eSIM?
Only if you want data while the ship is sailing. The port eSIM covers you ashore; GigSky is what connects you mid-ocean. Many cruisers run both and toggle between them.
Should I buy before I leave home?
Yes — install and set up any cruise eSIM over WiFi before you sail, since activation needs internet you won't have cheaply once aboard. See the at-sea vs in-port guide.
