Do You Need Cash for an Antarctic Cruise? How Does the Internet Work? A Complete Guide to Currency and Getting Online

When planning an Antarctic cruise, what concerns many people most are the questions related to payment and internet during the journey:

• Is there internet in Antarctica?
• Is the cruise Wi-Fi very slow?
• How much cash should you bring?
• Can you pay by credit card?
• What currency should you exchange for Argentina?

Here are the quick answers first:

• Antarctica has no mobile internet and no official currency.
• Cruises offer satellite Wi-Fi (most include 5GB of free data).
• Onboard transactions are primarily in US dollars, and credit cards are accepted.
• If passing through Argentina, you'll need to prepare Argentine pesos (ARS).

Below is a complete guide to help travellers prepare before departure.

The answer is: Antarctica has no mobile network—you can only use the satellite Wi-Fi provided by the cruise ship. Antarctica has no 4G or 5G base stations, and no commercial telecom services. An ordinary mobile SIM card cannot pick up a signal in Antarctica, so you cannot use mobile data or make calls directly. If travellers wish to go online, the only way is through the satellite communication system provided by the cruise ship.

Take the polar expedition brand Quark Expeditions as an example. Its Antarctic ships, such as the World Voyager and Ultramarine, currently offer:

• 5GB of free data per passenger
• Additional purchase required beyond the data allowance
• The cost is about US$30–40 per GB

Plans may vary slightly between cruise operators, but all Antarctic cruises rely on satellite internet.

Overall, it is not as stable as on land or on ordinary cruises. As you are sailing through one of the world's most remote waters, the internet relies entirely on satellite equipment, so you may experience:

• Slower speeds
• Weakened signal
• Brief interruptions

Suitable for:

• Sending WhatsApp, Messenger and LINE messages
• Basic web browsing
• Sending a small number of photos

Not recommended for:

• Audio and video streaming
• Video conferencing
• Large cloud backups

For everyday communication, 5GB is usually enough for a 10–14 day journey; but if you upload videos frequently, you may well run out early. Before departure, we recommend:

• Turning off automatic updates
• Turn off photo cloud sync
• Download offline maps and documents in advance

Antarctic cruises usually offer onboard Wi-Fi, but the connection relies on satellite links, so speed and stability may be affected by the weather and the ship's location.[/caption]

Yes, but not too much.Antarctica has no official currency, and all spending takes place on board the cruise ship. Take the Quark Expedition World Explorer as an example: onboard transactions are generally priced in US dollars (USD). Most Antarctic cruises:

• Accept Visa
• Accept MasterCard
• Link purchases to your cabin key card
• Settle everything by card at the end of the voyage

As a result, in most cases a credit card is all you need to make purchases. Even so, it is advisable to carry a small amount of US dollars in cash for:

• Small purchases at ports
• Tips
• Use when the system is temporarily offline

On an Antarctic cruise, most spending takes place in the lounge, bars and public areas, where credit cards are usually accepted on board.[/caption]

Most Antarctic cruises depart from Argentina, with common transit cities including Buenos Aires, while the embarkation city is Ushuaia. Argentina's official currency is the Argentine peso (ARS). In Buenos Aires, most large restaurants and shopping malls accept cards; in Ushuaia, however, some shops still prefer cash transactions. If you have a stopover or sightseeing itinerary, it is advisable to carry a small amount of pesos for convenience. If you need to exchange money, you can bring US dollars to Argentina and exchange them for pesos locally, which usually offers greater flexibility. However, since Argentina's exchange rate fluctuates considerably, it is advisable to exchange only the amount you expect to use. In short: use US dollars on the cruise, and pesos in Argentina. 👉 Further reading : Before or after your Antarctica cruise, take the chance to explore Buenos Aires and Ushuaia in Argentina [caption id="attachment_11983" align="alignnone" width="1024"]

In Ushuaia, Argentina, some restaurants and shops still operate mainly on a cash basis, so we recommend keeping some Argentine pesos or small-denomination US dollars on hand.[/caption]
