# Using your phone on a cruise: carrier cruise passes at sea, an eSIM in port

At sea your phone uses the ship's network. The AT&T cruise package is $20 a day with 500MB (checked on October 29, 2026, [AT&T: cellular at sea](https://www.att.com/wireless/what-is-cellular-at-sea/)). Verizon's Cruise Daily Pass is $20 a day from 12 miles offshore ([Verizon: Cruise Daily Pass](https://www.verizon.com/support/international-cruise-inflight-daily-pass-faqs/)).

This site is not affiliated with any carrier named on this page; we sell eSIMs. [How we compare](https://esimworld.us/how-we-compare/)

You may not need an eSIM. Many US plans already include Mexico and Canada, so check your plan before you buy anything for a Mexican port. At sea an eSIM does not help: it works in port, not at sea, because ship networks are separate.

Two bill traps come first: on AT&T's Day Pass, a call or text on the ship starts a $20 day even with data roaming off. At Verizon, background data with Wi-Fi off can start the $20 Cruise Daily Pass. We compare public packages; check your own plan.

## What happens to your phone at sea?

At sea your phone uses the ship's own maritime network, which AT&T calls cellular at sea. AT&T's Day Pass works on 400+ cruise ships, and T-Mobile lists 533 (checked on October 29, 2026 and October 29, 2026, [T-Mobile cruises](https://www.t-mobile.com/cell-phone-plans/international-roaming-plans/cruises)).

Verizon covers land with TravelPass and the sea with a separate Cruise Daily Pass. AT&T's Day Pass covers listed ships, at $20 a day instead of $12. Our eSIM works in port, not at sea: ship networks are separate.

AT&T's 24-hour day starts the first time you use data, text, or make or take a call on a listed ship ([AT&T: International Day Pass](https://www.att.com/international/day-pass/)). Verizon's Cruise Daily Pass starts when you make or answer a call, send a text or use data aboard ([Verizon: cruise and in-flight passes](https://www.verizon.com/support/international-cruise-inflight-daily-pass-faqs/)).

Background data counts when Wi-Fi is off, and Verizon names software updates, app refreshes and syncing. You don't have to open an app to start a pass.

## AT&T, Verizon and T-Mobile at sea: passes and prices

At sea, the AT&T cruise package is $20 a day per line with 500MB. Verizon's Cruise Daily Pass is also $20 a day per line, with 0.5 GB; T-Mobile bills what you use (checked on October 29, 2026).

| Carrier | At sea | Data allowance | After the allowance | Where it stops |
|---|---|---|---|---|
| AT&T (postpaid) | Day Pass, $20 a day per line, talk and text included; Elite 2.0 $15 a day per line | 500MB a day | Reduced speed | Listed ships (400+); pay-per-use without the pass |
| Verizon (postpaid) | Cruise Daily Pass, $20 a day per line, calls to and from the US and texts | 0.5 GB high-speed | 3G; an extra 0.5 GB is $10 | Listed ships, 12 miles or more from shore; not on land |
| T-Mobile (postpaid) | "Pay for the data, text, and voice you use" | None named | Rates only in T-Mobile's search tool | 533 ships on T-Mobile's list |
| Xfinity Mobile | Not covered | None | None | Roaming and Global Travel Pass do not cover cruises |
| Spectrum Mobile | No data on cruises | None | None | Spectrum's plans page |
| US Mobile | Not covered | None | None | Roaming does not cover ships |

Checked on October 29, 2026: [AT&T at sea](https://www.att.com/wireless/what-is-cellular-at-sea/), [AT&T Elite 2.0](https://www.att.com/support/article/wireless/KM1486292/), [Verizon](https://www.verizon.com/support/international-cruise-inflight-daily-pass-faqs/), [T-Mobile](https://www.t-mobile.com/cell-phone-plans/international-roaming-plans/cruises), [Xfinity](https://www.xfinity.com/support/articles/traveling-internationally), [Spectrum](https://www.spectrum.com/mobile/plans/international), [US Mobile](https://www.usmobile.com/international-roaming-phone-plans).

### The AT&T bill: $20 for land and sea on the same day

A port day can put the phone on a land network and on the ship within the same 24 hours. AT&T bills that day once, at $20, rather than a $12 land day plus a $20 sea day (checked on October 29, 2026, [AT&T: International Day Pass](https://www.att.com/international/day-pass/)).

AT&T's cruise article prints a cap of 10 days in one billing cycle for land-only travel ([AT&T: cellular at sea](https://www.att.com/wireless/what-is-cellular-at-sea/)). It does not say whether sea days count toward that cap.

A seven-day cruise on which the phone uses the ship every day comes to 7 × $20 = $140 per line (our arithmetic). Seven days is under 10, so that figure holds whether or not the cap reaches sea days.

If the phone uses the ship on only two of those seven days, the bill is 2 × $20 = $40 (our arithmetic). AT&T charges "only for the days you actually use cellular talk, text, and data".

AT&T Cruise Basic and Cruise Plus were replaced "as of April 16, 2025", AT&T's cruise article says. A page that still quotes a price for either plan is out of date.

Without the pass, AT&T charges $2.05 per MB on cruise ships, $4 a minute for calls and $1 per text ([AT&T: pay-per-use rates](https://www.att.com/international/pay-per-use-rates/)). At that rate 10MB costs $20.50, more than a day on the pass (our arithmetic).

Data roaming off on the AT&T line keeps data from opening a session. A call or a text on that line still opens one.

### Verizon: the pass at sea, TravelPass on land

The Cruise Daily Pass works on listed ships 12 miles or more from shore. Verizon adds: "Charges only apply on the days you use service onboard a cruise ship" (checked on October 29, 2026, [Verizon: cruise and in-flight passes](https://www.verizon.com/support/international-cruise-inflight-daily-pass-faqs/)). On land in port, Verizon points you to TravelPass or its monthly plan.

A Verizon cruise week is therefore a mix: $20 for each day the phone uses the ship, and TravelPass or the monthly plan in port. Verizon's TravelPass FAQs add that "TravelPass days aren't eligible for use on cruise ships" ([Verizon: TravelPass FAQs](https://www.verizon.com/support/travelpass-faqs/)).

On TravelPass in port, a session starts when you "make or answer a phone call, send a text or use data" in a TravelPass country. At sea, Verizon says you "can turn off cellular data" if you don't want background data to start the pass. A call or a text still starts it.

### T-Mobile: no price to quote

T-Mobile cruise roaming is billed per use, at rates published only inside an interactive search we did not capture, so we print no number. Its cruise page advises turning roaming off while the ship is docked at a U.S. port (checked on October 29, 2026, [T-Mobile cruises](https://www.t-mobile.com/cell-phone-plans/international-roaming-plans/cruises)).

The FAQ on that page still shows a 1-day pass price that differs from T-Mobile's current pass page, so we do not quote it. Plan details for each carrier are on [T-Mobile roaming](https://esimworld.us/roaming/t-mobile/), [AT&T roaming](https://esimworld.us/roaming/att/) and [Verizon roaming](https://esimworld.us/roaming/verizon/).

<a id="ship-wifi"></a>

## What about ship Wi-Fi?

Ship Wi-Fi is sold by your cruise line, not your carrier, so its price is on the cruise line's page; we print none. Set it against the $20 a day the AT&T and Verizon passes cost at sea (checked on October 29, 2026).

If the ship Wi-Fi package costs less per day than $20, Wi-Fi wins for data. A carrier pass wins when you need calls and texts on your own number without an app.

AT&T's cruise article advises turning Airplane Mode on while you use the ship's Wi-Fi ([AT&T: cellular at sea](https://www.att.com/wireless/what-is-cellular-at-sea/)). It also warns that "using AT&T's Wi-Fi calling when abroad will still incur charges, as it's charged like cellular calling". The article's alternative is a calling app over the ship's Wi-Fi.

<a id="in-port"></a>

## In port: when does an eSIM make sense?

In port a travel eSIM works: our Mexico plan is $3.99 for 1GB over 7 days, data only. Your US number stays on your main line, and on most of our plans the days start when the eSIM first connects at your destination.

So you can install the eSIM at home before the cruise; check the activation rule shown on your plan before you buy. On supported iPhone models, two eSIMs can be active at the same time ([Apple: two eSIMs on iPhone](https://support.apple.com/en-us/118227)). Apple's example: one for your home number, one for the place you're visiting.

Check your phone first: [Is my phone unlocked?](https://esimworld.us/unlock/is-my-phone-unlocked/) and [Does my phone support eSIM?](https://esimworld.us/esim-compatible-phones/) Then pick a plan for each port country.

| Port country | Plan example | What it is |
|---|---|---|
| Mexico | $3.99 | 1GB, 7 days, data only ([Mexico eSIM](https://esimworld.us/esim-mexico/)) |
| Bahamas | $6.99 | 1GB, 7 days, data only ([Bahamas eSIM](https://esimworld.us/esim-bahamas/)) |
| Jamaica | $7.99 | 1GB, 7 days, data only ([Jamaica eSIM](https://esimworld.us/esim-jamaica/)) |
| Dominican Republic | $5.99 | 1GB, 7 days, data only ([Dominican Republic eSIM](https://esimworld.us/esim-dominican-republic/)) |

Our plans are per country, one storefront each, and we do not claim a plan works in every port of a route. Caribbean data costs two to three times what Europe does across the sellers we checked on October 29, 2026. For other Caribbean ports, see [SIM cards for the Caribbean islands](https://esimworld.us/sim-card/caribbean-islands/).

An eSIM does not always win. If you visit one or two ports and your plan already covers the country, compare [roaming or eSIM](https://esimworld.us/roaming-or-esim/) first. Setup steps are in [how to install an eSIM](https://esimworld.us/how-to-install-esim/).

Turn data roaming on for the eSIM line, as its install steps say ([turn data roaming on or off](https://esimworld.us/help/data-roaming/#turn-on-off), [Apple: Data Roaming](https://support.apple.com/en-us/109037)). With data roaming off on the US line, that line's data does not start a carrier session. A call or a text on that line still can at AT&T and Verizon.

## How do you avoid charges on a cruise?

Keep cellular data and data roaming off at sea on your US line, and data will not start a $20 AT&T or Verizon day. A call or a text still starts one (checked on October 29, 2026).

AT&T's cruise article goes further on Airplane Mode at sea: "keep it in airplane mode when you're not using it" ([AT&T: cellular at sea](https://www.att.com/wireless/what-is-cellular-at-sea/)). It says to turn Airplane Mode off only to make a call, send a message or use data.

In port, turn Airplane Mode off and use the eSIM line for data. The Federal Communications Commission (FCC) says [roaming charges](https://esimworld.us/roaming/) may not appear on your bill for an additional billing cycle after you return ([FCC: international roaming](https://www.fcc.gov/consumers/guides/international-roaming)). Check the next statement too.

The switches for each line are in [turn data roaming on or off](https://esimworld.us/help/data-roaming/#turn-on-off).

<a id="in-flight"></a>

## What about the flight there?

Verizon sells an In-flight Daily Pass at $20 a day with 3G speeds, and T-Mobile offers free in-flight Wi-Fi on some airlines (checked on October 29, 2026). AT&T's Day Pass covers participating airlines but states no separate price in the air.

AT&T lists 19 participating airlines ([AT&T: destination list](https://www.att.com/support/article/wireless/KM1395068/)). Without a pass, its rate in the air is $4 a minute and $2.05 per MB ([AT&T: pay-per-use rates](https://www.att.com/international/pay-per-use-rates/)). On Verizon, reply FLIGHT to the text on board to start the pass ([Verizon: cruise and in-flight passes](https://www.verizon.com/support/international-cruise-inflight-daily-pass-faqs/)).

T-Mobile's free in-flight Wi-Fi runs through airline loyalty programs on Delta, Alaska, Hawaiian and Southwest, including some international flights. Texting works over [Wi-Fi Calling](https://esimworld.us/help/keep-your-us-number/) ([T-Mobile in-flight](https://www.t-mobile.com/support/coverage/t-mobile-in-flight-connections-on-us)). Xfinity, Spectrum and US Mobile say their roaming does not cover planes.

For the whole trip, weigh a carrier pass against a plan on [roaming or eSIM](https://esimworld.us/roaming-or-esim/).

## Frequently asked questions

### How do I use my phone on a cruise without getting charged?

Turn off cellular data and data roaming on your US line at sea, then use ship Wi-Fi or a carrier cruise pass. A call or a text still starts AT&T's $20 day or Verizon's Cruise Daily Pass. In port, use an eSIM line for data.

### Does an eSIM work on a cruise ship?

No, not at sea: ship networks are separate, and our eSIMs connect to local networks on land. In port an eSIM works. Your US number stays on your main line, and most of our plans are data only; check the plan's calls/SMS fields.

### Should I put my phone in Airplane Mode on a cruise?

Yes, when you're not using it: AT&T's cruise article says to "keep it in airplane mode when you're not using it". It also says to turn Airplane Mode on while you use the ship's Wi-Fi. In port, switch Airplane Mode off once your eSIM line is set up.

### Does Verizon TravelPass work on a cruise?

No. There is no Verizon cruise TravelPass: Verizon's TravelPass FAQs say "TravelPass days aren't eligible for use on cruise ships". At sea Verizon sells the Cruise Daily Pass, $20 a day for 0.5 GB of high-speed data, 12 miles or more from shore.
