Yes, you can use your cell phone on a cruise ship, but it will be expensive unless you plan ahead
Your phone will work on a cruise ship, but the cost depends on which network you choose. Most cruise lines offer their own Wi-Fi calling and data plans, which are cheaper than international roaming rates but still cost money. If you do nothing before boarding, your phone will try to connect to whatever network is available, and you will be charged roaming rates that can reach $5 to $15 per minute for calls and $1 to $5 per megabyte for data — costs that add up fast.
The practical choice is to buy a cruise line data package before you board, turn off roaming entirely, or use only Wi-Fi calling through apps like WhatsApp and Messenger. Which option makes sense depends on how much you plan to use your phone and whether you need to stay reachable by regular phone calls.
Key Takeaways
- Cruise line Wi-Fi packages cost $10 to $20 per day for data and calling, which is far cheaper than international roaming rates of $5 to $15 per minute.
- Your phone will automatically connect to whatever network is available at sea unless you disable roaming, so turning off roaming before you board prevents accidental charges.
- Free Wi-Fi calling through apps like WhatsApp, Messenger, and FaceTime works on most cruise ship Wi-Fi networks and requires no extra payment.
- Turning your phone to airplane mode and using only Wi-Fi calling is the cheapest option if you do not need to receive regular phone calls.
- Costs vary by cruise line and destination, so check your cruise line's website for current pricing before you board.
How cruise ship cell networks charge you
When your phone is at sea, it connects to networks operated by the cruise ship itself or by maritime service providers like Viasat and Inmarsat. These are not the same as your home carrier's network. Your home carrier — AT&T, Verizon, T-Mobile, or another provider — will charge you international roaming rates for any call, text, or data that passes through these maritime networks.
International roaming rates are set by your home carrier and vary by destination and carrier, but they are consistently high. A single call can cost $5 to $15 per minute. A text message costs $0.50 to $2. Data is often charged per megabyte rather than per gigabyte, which means a single email with a photo attachment can cost $1 to $5. These charges happen whether you initiated the call or someone texted you.
The cruise line's own Wi-Fi and calling plans are cheaper because they are flat daily or weekly rates rather than per-minute charges. Most cruise lines charge $10 to $20 per day for a data and calling package, or $50 to $80 for a week-long cruise. This is still a cost, but it is predictable and far lower than roaming charges.
Cruise line Wi-Fi and calling packages
Most major cruise lines — Carnival, Royal Caribbean, Disney Cruise Line, Norwegian, and others — offer their own Wi-Fi service and cellular calling plans. These plans let your phone connect to the ship's network and use data and calling at a flat rate instead of per-minute charges. You buy the plan before you board or during the first day of your cruise through the cruise line's app or onboard kiosk.
Plans typically come in two types: Wi-Fi only, which lets you use apps like WhatsApp and Messenger but not regular phone calls, and Wi-Fi plus cellular, which adds the ability to make and receive regular phone calls. Wi-Fi only plans cost $10 to $15 per day. Wi-Fi plus cellular plans cost $15 to $20 per day. Some cruise lines offer weekly passes at a discount if you are cruising for seven days or longer.
The quality of these networks varies. On newer ships, the Wi-Fi is usually fast enough for video calls and streaming. On older ships, it may be slow and drop frequently. Check your cruise line's website or recent reviews to see what other passengers report about network speed on your specific ship.
Using Wi-Fi calling apps instead of cellular plans
If you buy only the Wi-Fi plan and turn off cellular roaming, you can still make and receive calls for free through apps like WhatsApp, Messenger, FaceTime, Google Meet, and Skype. These apps use the ship's Wi-Fi network instead of the cellular network, so they do not trigger roaming charges. Anyone you want to call needs to have the same app installed, but most people already do.
This option works well if the people you need to reach are comfortable using apps, or if you only need to check in with family once a day. It does not work if you need to receive calls from people who only have your regular phone number, such as your doctor's office or your bank. In those cases, you would need the cellular calling plan.
Wi-Fi calling apps are also useful as a backup. Even if you buy the cellular plan, you can use apps for calls to people who have them, which saves your plan's minutes for calls that require the cellular network.
Turning off roaming to avoid surprise charges
The single most important step is to turn off cellular roaming before you board the ship. If you leave roaming on and do nothing else, your phone will connect to whatever maritime network is available, and you will be charged roaming rates for every call, text, and data use.
On an iPhone, go to Settings, then Cellular, then turn off Cellular Data and turn off Roaming. On an Android phone, go to Settings, then Network and Internet, then Mobile Network, then turn off Data Roaming. You can still use Wi-Fi calling and apps once you are on the ship, but your phone will not automatically connect to the maritime cellular network.
If you turn off roaming and then decide you want the cruise line's cellular plan, you can turn roaming back on after you buy the plan. The cruise line's plan will override your home carrier's roaming rates.
What happens in port and near land
When your ship is docked at a port or close enough to land that your phone can reach a local network, your phone may connect to that local carrier instead of the ship's network. This is often cheaper than maritime roaming but still more expensive than your home plan. Some ports have good local coverage; others do not.
If you have roaming turned off, your phone will not connect to local networks either, so you will have no cellular service in port unless you turn roaming back on. Many passengers turn roaming back on while in port to use local networks, then turn it off again before leaving port. This requires remembering to switch it each time, which is straightforward to forget.
A simpler approach is to keep roaming off the entire cruise and rely on Wi-Fi calling and apps everywhere. Most ports have Wi-Fi available at the cruise terminal, in restaurants, and in shops, so you can still stay in touch.
Comparing your options by cost and use
| Option | Cost per day | Best for | Drawback |
|---|---|---|---|
| Roaming on (no plan) | $5–$15 per minute for calls; $1–$5 per MB for data | Emergency calls only | Charges add up very fast; straightforward to exceed $100 in a day |
| Cruise line Wi-Fi only | $10–$15 | Apps and messaging; no regular phone calls needed | Cannot receive calls to your phone number |
| Cruise line Wi-Fi plus cellular | $15–$20 | Regular phone calls and apps; staying fully reachable | Higher cost than Wi-Fi only |
| Wi-Fi only plus apps (roaming off) | $10–$15 | Apps and messaging; no regular phone calls needed | Cannot receive calls to your phone number; requires others to use apps |
| Airplane mode plus Wi-Fi (roaming off) | $0 | Minimal phone use; checking email and messages once a day | No cellular service; slow Wi-Fi on some ships |
Frequently Asked Questions
Will my phone automatically connect to the ship's network?
Your phone will try to connect to whatever cellular network is available, which at sea is usually a maritime network operated by the ship or a service provider. If roaming is turned on, your phone will connect automatically, and you will be charged roaming rates. If roaming is off, your phone will not connect to cellular networks, but you can still use Wi-Fi calling.
Can I use my regular phone plan on a cruise ship?
Your regular phone plan does not work on a cruise ship. Your home carrier charges international roaming rates for any service used at sea, which are much higher than your regular rates. You need to either buy the cruise line's plan or use Wi-Fi calling with roaming turned off.
What if I need to make an emergency call?
If you have roaming turned on, you can call 911 or your local emergency number, and you will be charged roaming rates afterward. If roaming is off, you can still call 911 through Wi-Fi calling if the ship has Wi-Fi. Tell the cruise line staff when ready if you have a medical emergency; they can contact emergency services and get you help faster than you can.
Do I have to buy a plan for the whole cruise?
No. Most cruise lines let you buy plans by the day, so you can buy a plan for only the days you need it. Some passengers buy a plan for the first and last day of the cruise to stay in touch before and after, and use Wi-Fi calling for the days in between.
Will Wi-Fi calling work if the ship's Wi-Fi is slow?
Wi-Fi calling works on slow connections, but the call quality will be poor — you may hear delays, cutting out, or echo. Video calling usually does not work on slow Wi-Fi. If the ship's Wi-Fi is consistently slow, the cellular plan may give you better call quality, though it will cost more.
