CruiseLink
Will the cruise line app chat notify you when your phone is locked?
No line promises it, and only one even mentions it. We read the chat pages, FAQs and app store listings of nine cruise lines on 4 Nov 2026. Holland America says, in a 2021 blog post, that notifications can alert you to messages. The other eight describe their chat without a word about what happens when your phone is in your pocket. Guests fill the gap on Cruise Critic, and what they describe, line after line and year after year, is the same: alerts arrive some of the time, and keeping the app open helps. Plan on checking the app, not on being told.
Why we checked
This is the question people actually ask. Cruise Critic’s Royal Caribbean board has a thread from 26 Feb 2026 asking whether you can “now get notifications when you receive a message in the Royal app, even when your phone is locked”. The Princess board asked it in March 2024, the Holland America board in June 2023, the Norwegian board in February 2022, and the Carnival board repeatedly since 2017. Every thread gets a handful of contradictory replies and no answer from the line. The pages that compare the apps, ours included, say what chat costs and who can use it, not whether a locked phone is told.
We also asked a search-grounded AI assistant on 4 Nov 2026. It said you “generally don’t have to keep the app open”, resting the whole claim on one Disney panelist’s answer. That is what happens when nobody has compiled the facts: a model generalises from the one it found.
Line by line
The middle column is what the line itself says, read from its own website or its own app store listing. The right-hand column is what guests report, with the date, because an alert that worked in 2023 may not work now and one that failed in 2022 may have been fixed. Forum reports are not evidence of how the app behaves on your sailing; they are evidence of how mixed the experience is.
| Line | What the line says about being alerted | What guests report |
|---|---|---|
| Royal Caribbean | Nothing. Its chat FAQ says chat is free on the ship’s Guest Wi-Fi and that a stateroom is connected automatically. Its App Store listing mentions a notification only “when you have plans” in the Daily Planner. | Cruise Critic, 26–27 Feb 2026: “it only works sometimes”; “Yes, there are notifications. But when (or even if) you get them is the issue”; on Allure that month, “sometimes I got notified, sometimes I didn’t” and some messages “took hours”; in January, one message took 22 minutes to cross two feet by the pool. Royal Caribbean Blog, testing on Mariner in Jan 2023: notifications “only about 20-30% of the time”, so the party had to keep opening the app. |
| Carnival (HUB) | Nothing for chat. The help page says chat is $5 per user for the voyage, ages 13 and over. The HUB app page describes notifications for your dining table, the muster drill and your turn to disembark, and none for messages. | Cruise Critic, Jun–Jul 2023, split down the middle. “Both people have to keep the Hub app on at all times to use it”; a husband who “never bothered to have app open which you need to do in order to get texts”; a 2018 family who “just had to look to see if there was any message”. Against that, “no missed texts at all” on Celebration in May 2023 and “no missed txt” for a group of twelve. |
| Disney (Navigator) | Nothing from Disney itself: the cruise contract and the App Store listing describe Onboard Chat without mentioning alerts, and we found nothing in the help centre. On planDisney, Disney’s own Q&A site answered by guest panelists rather than staff, one panelist wrote on 9 Mar 2024 that “push notifications for chat messages are available on all the ships, so be sure to enable this feature on your phone”, and another on 12 Jan 2026 said to make sure everyone’s notifications are turned on. | We found no recent guest reports either way, which is itself unusual for Disney. |
| Norwegian | Its current app page says nothing about messaging at all; it says only that the app uses no wifi minutes. A 2014 ncl.com leaflet for the previous iConcierge app said “push notifications must be accepted to be alerted of incoming calls and text messages”. We found nothing current. | Cruise Critic, Feb 2022, about Gem in Dec 2021: “we didn’t get notified that we had a new message, we had to open the app and look”. A reply advised letting the app run in the background because it “pulls” notifications rather than having them pushed. |
| Princess | Nothing. The onboard FAQ says you can chat with your children “anywhere on board” and says nothing about alerts. The App Store listing mentions chat only for reaching the crew. | Cruise Critic, 27 Mar 2024, about the app Princess was then replacing: “there was not a notification when a text came in. You had to have the chat feature open”; a red dot on the chat tab, with the real alert “blocked by default”; “everyone has been complaining about [this] since the first app”. We found no reports on the current app. |
| Holland America (Navigator) | The one line that says it. Its blog, 23 Jun 2021: “Notifications can be set up to send reminders and alerts for reservations, messages and more.” Its FAQ and App Store listing describe the chat as free with no internet purchase, and say nothing further about alerts. | Cruise Critic, 20–27 Jun 2023, mixed: “yes, it gives you both an audible and visual alert now” against “maybe 1/4 of the time” and “only work right if the app was open”; on Eurodam in May 2023, no alerts “unless we were actively in the app”. Readers of that 2021 blog post complained underneath it that the chat gave no notification at all. |
| Celebrity | Nothing for chat. Its FAQ says that with notifications on you receive “essential cruise travel updates and emergency messaging”. The App Store listing, like Royal Caribbean’s, promises a reminder when you have plans. | None found. |
| MSC (MSC for Me) | Nothing. msccruises.co.uk says the chat sends messages without an internet package and is for guests aged 16 and over. The App Store listing promises “real-time notifications for your bookings and key events”, not for chat. | None found. |
| Costa | The closest any line gets without saying it. The App Store listing: “CHAT | Don’t miss out on any message from your travel companions.” No mention of how you would know one had arrived. | None found. |

Why it is like this, probably
No line explains it, so this is our reading and nothing more. A cruise line’s chat runs on a server aboard the ship, over the ship’s own wifi, which is why none of it needs an internet package. The normal way an app alerts a locked iPhone or Android phone is different: the message goes from the app’s server out to Apple’s or Google’s push servers on the internet, and from there to the phone. A ship’s guest network may or may not let that round trip happen for a phone with no package. When it cannot, the app has only one other way to learn a message exists: ask the ship’s server itself, which it can do while it is running and cannot do once the phone has put it to sleep. That is the shape of every forum report above: fine with the app open, patchy in a pocket, and different from one ship, phone and sailing to the next. One Norwegian guest put it the same way in February 2022: the app “pulls” notifications rather than having them pushed.
It also explains why “turn your notifications on” is the advice from every panelist and half the forum replies, and why it only sometimes works. The permission is necessary. It is not what decides whether the alert ever reaches the phone.
How to give the line’s chat its best chance
- Allow notifications for the app before you sail, on every phone in the group. This is the one thing the lines, the panelists and the forums all agree on, and the only setting any line asks for.
- Let it run in the background. On iPhone, Settings > General > Background App Refresh, with the line’s app switched on. On Android, open the app’s battery settings and take it out of any optimised or restricted mode. These were the fixes forum members suggested for Norwegian and Carnival; no line says they are needed, and nobody has measured whether they help.
- Test it on embarkation day, on the ship’s wifi, before you rely on it: one person locks their phone and walks off, the other sends a message, and you time what happens. If nothing arrives, you have learned it on deck five rather than at the moment someone is missing.
- Agree to check the app at set times, or to message whenever you move. A Carnival parent on Cruise Critic in 2023 described using exactly that rule with their children in 2018: text in the app whenever you go from one place to another, and nobody needed an alert. Which lines let a child use the chat at all, and what a parent has to switch on, is its own question.
- Have a meeting point that needs no phone. A place and a time survives a flat battery, a silenced app and a notification that never came.
Remember too that the line’s chat stops at the gangway: on a port day the question of alerts does not arise, because no line’s chat says it reaches you ashore.
Where CruiseLink fits, and where it does not
CruiseLink was built around this exact question. The thing it has to get right is whether a message reaches a phone that is locked, in a pocket, on another deck, and it does it differently from the lines’ apps: messages pass directly between your group’s phones over Bluetooth and the ship’s local wifi, and the alert is posted by the app on your own phone the moment a message lands. No internet, no package, no round trip to anyone’s servers. On iPhone the app registers with iOS to be woken for Bluetooth in the background; on Android it runs as a foreground service, which is why it shows a permanent notification while it is working. In our own testing, two locked iPhones exchanged messages, and in September 2026 a tester’s Galaxy S25 FE completed 836 exchanges in twelve and a half hours with the app open for under three minutes of that time. Those were tests at home and in a town, not on a ship, and we say so.
Its limits are real and you should know them before you plan around it. Everyone has to install it and join the group before you sail. It reaches your own group only, not the whole ship. And it is not instant across a large vessel: a message waits until your phones come within reach of each other, directly or through another phone in your group, so the alert arrives when the message does, which on a 300-metre ship may be minutes later rather than seconds. There is no push-to-talk voice; it is text. It also needs an iPhone 11 or later, or Android 9 or later, which is stricter than most of the lines’ own apps.
So the honest advice is both. On Holland America, the one line that says its chat alerts you, and on Disney, where the panelists say the same, start with the line’s app. On every line, install the line’s app anyway: it is free, and on a quiet part of the ship it may well beat anything else. Add CruiseLink for the moment the line’s alert does not come, which, on the evidence above, is a moment every line’s guests describe. The 15-minute connectivity checklist covers setting up both before you leave home wifi behind.
