Quick answer: Most big ships now offer satellite internet packages sold per device per day. Buy before you sail for presale discounts, buy only for the devices you need, and turn off automatic updates and cloud backups. Avoid your phone's cellular roaming at sea unless you know your carrier's maritime rates.

Internet at sea has improved a lot with low-earth-orbit satellite service on many ships, but packages still cost extra on most lines.

How it works

Ships connect to satellites, then share that connection over the ship's Wi-Fi. Packages are usually sold per device, per day, for the whole cruise.

Ways to save

Buy in the presale window before sailing.
Share one device's package if your line allows switching devices.
Download maps, movies and boarding passes before boarding.
Turn off auto-updates, photo backup and video autoplay.
Use port Wi-Fi or local SIM/eSIM plans when ashore.

Avoid surprise roaming charges

At sea, phones may connect to the ship's maritime cellular network, which is billed separately and can be expensive. Use airplane mode with Wi-Fi on unless you have checked your carrier's cruise rates.

Frequently asked questions

Can I stream video on cruise Wi-Fi?

Many lines' higher tiers allow streaming, but speeds vary by ship and location.

Is cruise Wi-Fi worth it?

If you need to work or stay in touch daily, yes; otherwise port Wi-Fi may be enough.
