Can you text on a cruise ship?
Yes, but not the way it works at home. Out at sea there is no normal mobile network, only the ship's own satellite one, and it charges roaming rates per message. To text without a bill you need either the ship's wifi package, the cruise line's app, or an app that passes messages directly between phones.
What happens to your phone at sea
In port you will usually pick up a local network and everything behaves normally, give or take roaming charges. Once the ship is a few miles out, that disappears. What is left is the ship's own maritime cellular service, billed as roaming at rates set by your provider, not the cruise line, and it is the single most common source of a nasty bill when someone gets home.
This is why nearly every experienced cruiser tells you to put the phone in airplane mode the moment you sail, then switch wifi and Bluetooth back on by hand. Airplane mode blocks the maritime network; wifi and Bluetooth carry on working.
The four ways people text onboard
| Route | Reaches | Cost |
|---|---|---|
| Ship's internet package | Anyone, including home | Sold per person per day, or per voyage. The expensive option for a family. |
| Cruise line's own app | Others on your sailing | Varies by line. Royal Caribbean has included it since 2023; Carnival charges a one-off fee per person for HUB chat. |
| Maritime roaming (SMS) | Anyone | Per message, at roaming rates. Easy to run up without noticing. |
| Phone-to-phone app | Only your own group | Free. No package, no signal. |
Why iMessage and WhatsApp do not just work
People reasonably assume that if two iPhones are sitting in the same room, iMessage should manage it. It will not. iMessage, WhatsApp, Messenger and the rest all send your message to a server on the internet and back down to the other phone. Take the internet away and there is nothing for them to talk to, however close together the two phones are.
There is one halfway case worth knowing: if everyone in your group is connected to the ship's wifi network, some lines allow guests to reach each other across it, and iMessage may work between you without an internet package. It depends entirely on whether that ship's network permits it, and plenty do not.
Texting people at home
There is no free route for this. If you need to reach someone ashore you are buying an internet package, using the ship's maritime network at roaming rates, or waiting for a port and using local wifi in a café. Many people buy one package for the household, on one phone, and pass messages onward from there.
Texting people you are travelling with
This is the part that does not need to cost anything, and it is most of what people actually want. CruiseLink passes short messages directly between the phones in your group, over Bluetooth and over the ship's own wifi network where it is allowed. No package, no account, free on the App Store.
The honest limit: it only reaches the people in your group, and a message travels when phones come near each other, so it is not instant from one end of a large ship to the other. Everyone needs it installed before you sail. Here is how to do that properly.
Common questions
Does the ship's wifi package cover everyone in my cabin?
Usually not. Packages are normally sold per device or per person, which is exactly why a family ends up buying one and sharing news by shouting across the pool deck.
Can I receive texts without buying anything?
If your phone is in airplane mode, no. If you let it connect to the ship's maritime network, incoming SMS may arrive and your provider may charge you for the privilege.
What about an eSIM?
A travel eSIM is useful in port, where it uses the local network. It does nothing at sea, because there is no local network to use.
