Saint Lucia (St Lucia) – known for its beaches, lovely weather & stunning landscaped.
It is also the Caribbean nation with the most mountains.
The nation is a popular stop for cruise ships.
And that is understandable, as there is so much to see and do in this country.
From hiking on the Gros Piton to swimming and snorkeling on Anse Chastanet Beach.
And of course, you will explore Marigot Bay.
You may not even have time to do all of that when you arrive in St Lucia by cruise ship – that is fine.
Come back another time as a standalone trip, as you certainly do not want to miss out.
While it is inevitable that you will share plenty of photos and videos of St Lucia online, you should know that international roaming can be expensive.
Luckily, Saint Lucian SIM cards are inexpensive (and you can even get one for free) – so is the cost of mobile data on this island nation.
You can get a Saint Lucian SIM card for 15 XCD (5.55 USD) from Digicel in their stores or from resellers. Flow hands out SIM cards for free, but be prepared to buy a plan on the spot. They are not sold at La Tourney-Hewanorra International Airport (UVF) nor Vigie-George F. L. Charles Airport (SLU).
There are no roaming plans that can beat these prices. Unless you can roam for free in St Lucia, of course, but do not count on that.
Before you decide to get yourself a free SIM card from Flow, there are quite some things to know about Saint Lucian SIM cards.
In this guide, I will tell you everything you need to know about buying a SIM card in St Lucia. Let's do this.

Can You Buy a SIM Card in St Lucia?
You can buy a Saint Lucian SIM card from Digicel and Flow as a tourist. There is nothing preventing travelers from buying a SIM card in St Lucia.
You do have to comply with the SIM card registration regulations.
Moreover, your phone has to support the frequencies used in St Lucia.
Finally, your phone needs to be unlocked (SIM-lock free) to use a Saint Lucian SIM card.
Where Can You Buy a SIM Card in St Lucia?
You can get a Grenadian SIM card in the official stores of Digicel and Flow and from resellers. They are not available at La Tourney-Hewanorra International Airport (UVF) nor Vigie-George F. L. Charles Airport (SLU).
You can expect to pay the following for Saint Lucian SIM cards:
- Digicel St. Lucia: 25 XCD
- Flow St. Lucia: Free!
Can You Use Your Phone in St Lucia?
St Lucia uses GSM for their cellular communications, meaning that you need a GSM-capable phone to use your phone in the country. Fortunately, there is about a 99% chance your phone supports GSM.
Besides that, you need to be aware of the ITU regions to determine whether your phone will work in other parts of the world.
Although there are 3 ITU regions, you only need to know these two terms: American frequencies and European frequencies.
Africa, Asia (including the Middle East), Europe & Oceania (ITU Regions 1 & 3) typically use European frequencies, meaning phones bought in those regions can be used in countries using European frequencies without issues.
The Americas (North-, Central– & South America + the Caribbean), ITU Region 2, use American frequencies, which are different from the European frequencies.
St Lucia uses a mix of American frequencies and European frequencies for 2G and 3G, depending on the mobile operator. 4G/LTE is exclusively on American frequencies.
If you bought your phone in the Americas (ITU region 2) and have a low/medium-end device (without Tri-Band or Quad-Band) support, you want to go with Flow St. Lucia.
It supports traditional American frequencies on 2G, 3G & 4G/LTE, meaning that you can take full advantage of its network.
If you purchased your phone in Africa, Asia, Europe, or Oceania (ITU regions 1 & 3) and have a low/medium-end device (without Tri-Band or Quad-Band) support, you want to go with Digicel St. Lucia.
It supports traditional European frequencies on 2G and 3G, but you will not be able to use its 4G/LTE network.
Suppose you have a medium/high-end device with Tri-Band or Quad-Band support. In that case, you can go with any mobile operator, as your phone will support both American frequencies and European frequencies, even on 4G/LTE.
Mobile Operators, Networks & Frequencies in St Lucia
St Lucia has two mobile operators offering prepaid services:
- Digicel St. Lucia
- Flow St. Lucia
The following frequencies are used in St Lucia:
- 2G: 850 MHz, 900 MHz & 1800 MHz
- 3G: 850 MHz, 1900 MHz & 2100 MHz
- 4G/LTE: 700 MHz (Band 13 & Band 17)
You can learn more about frequencies in the video below.
To check whether your phone will work in St Lucia, check out this page by Will My Phone Work (may be outdated or inaccurate at times).
Again, make sure your phone is unlocked. Otherwise, you will not be able to use any SIM card except the one from your home operator (meaning you have to roam internationally or buy another unlocked phone that does support the frequencies listed above).
If you want to learn how international roaming works, this guide explains it in-depth. If you wonder why it is often so expensive to roam, this article explains the hidden reason they do not want you to know.
VoLTE & VoWiFi in St Lucia
Both VoLTE (Voice over LTE (4G) – also known as HD Voice) and VoWiFi (Voice over WiFi – also known as WiFI calling) are not offered by the mobile operators in St Lucia (yet).
This means that when you make a call, your phone will downgrade to 3G (or 2G when 3G is not available) instead of staying connected to 4G/LTE.
This is also why you often cannot use mobile while calling if not connected to WiFi.
VoWiFi is, as the name implies, calling on a WiFi connection as opposed to on a cellular network.
5G NR in St Lucia
5G NR is not available in St Lucia as of 2022, and the Saint Lucian government has not made any indications of when they will auction 5G licenses.
Best SIM Card St Lucia
If you want to buy the best SIM card in St Lucia, I recommend going with Digicel. It has the best coverage and the fastest speeds. Moreover, Digicel also has attractive plans (Prime Bundles) with dedicated data allowances for Prime apps, TikTok & YouTube (up to 45 GB/app).
Best eSIM in St Lucia
Unfortunately, none of the mobile operators offer eSIM (to prepaid customers) in St Lucia yet.
However, you can get the St Lucia (Lucnet) eSIM from Airalo with 1 GB of data valid for 7 days.
With this eSIM, you can skip St Lucia's SIM card registration scheme entirely and use it immediately upon arriving in St Lucia!
If you plan on visiting other neighboring Caribbean nations, consider the Island Hopper eSIM with 1 GB of data (7 days) in St Lucia and these other islands:
With the Island Hopper eSIM, you can save a lot of money by skipping the initial SIM card costs per country you visit – averaging 8 USD/country in the Caribbean!
SIM Card Registration St Lucia
SIM card registration, with the use of your passport information, is mandatory in St Lucia. This will be done at the point of sale.
St Lucia Mobile Internet Prices & Insights
Mobile data in St Lucia has always been quite affordable compared to other countries and territories in the region.
It was not uncommon to spend at least 10 USD or 20 USD on just 1 GB of data in the Caribbean.
However, those criminal prices have vanished over the years with the improvement of telecommunications infrastructure throughout the region.
So, how expensive is mobile data in St Lucia?
The average price for 1 GB of data in St Lucia is 2.62 USD, below the Caribbean average of 4.44 USD. The world average is 4.07 USD.
Compared to 2019's figures, the average cost of 1 GB of data has gone down by 45.9%.
While there is not much information about mobile data speeds in the country because not many people do speed tests there, I can mention something about speeds.
In the Caribbean, you can expect your speeds to range between 10 Mbps and 25 Mbps.
With reasonably priced SIM cards, close to excellent nationwide coverage, decent mobile download speeds, and low mobile data rates, you should have a smooth network experience in St Lucia.
Currency in St Lucia
St Lucia uses the East Caribbean Dollar with the symbol XCD (which will be used throughout this guide).
However, prices are often listed as ECD, EC$, or $. For example, 25 XCD = ECD/EC$/$ 25.
XCD is pegged 2.70:1 to the US Dollar (USD), meaning that 2.70 XCD is 1 USD. 27.10 XCD would be 10 USD. 270 is 100 USD, etc.
1 XCD is 0.37 USD, 10 XCD is 3.70 USD, 100 XCD is 37 USD – you know the drill.
For up-to-date XCD:your currency (let's say Euro) exchange rates, use the Wise Currency Converter tool.
If your credit/debit card charges you foreign exchange fees, get yourself a Wise Borderless Account and Debit Card.
Their fees are MUCH lower than banks, and credit card companies charge you (and Wise is transparent about their fees, unlike banks).
I have saved literal THOUSANDS of Euros, my main currency, when using Wise abroad when traveling compared to my debit and credit cards. Open a Wise account FREE!

Other Ways to Stay Connected When Traveling in St Lucia
I would highly encourage anyone visiting St Lucia to get themselves a Saint Lucian SIM card – you will be saving a lot of money when you do so.
However, for some, getting a Saint Lucian SIM card is not an option.
For example, your device may be SIM-locked, meaning that you cannot use any other SIM card other than the SIM card provided by your mobile operator.
There are other ways to stay online while in St Lucia, but they may not be cheap.
However, these methods may be more expensive than getting a SIM card from the local mobile operators.
International Roaming
International roaming is the most convenient way to stay connected when traveling in other countries because you do not have to buy a new SIM card, have to deal with SIM card registration regulations, nor have multiple phone numbers to deal with.
However, international roaming has proven to be expensive in many cases, especially compared to buying local SIM cards. That is why many travelers are not fond of international roaming.
Find out whether your mobile operator has attractive roaming rates for St Lucia here.
Using an International SIM Card or Travel SIM Card
International SIM cards are SIM cards made for the traveler in mind.
Using them is often cheaper than international roaming.
However, they are almost always more expensive than using a local SIM card.
There are many other advantages and disadvantages of getting international SIM cards, which you can learn about here.
Using a Mobile Hotspot (Pocket WIFI)
Mobile hotspots, or pocket WIFI, are small devices that connect to the local mobile operators of the country you are visiting.
Mobile hotspots are ideal for families or those traveling in a large group, as they allow you to connect multiple devices to one hotspot without the need of each traveler having to buy a SIM card.
You can either buy a mobile hotspot or rent one.
Using Free WIFI Networks
Using free WIFI connections is the cheapest way to stay connected because they are free.
The major downside of trying to use WIFI hotspots is that you will have to locate them, and they are not available on every corner in St Lucia.
Make sure to protect your internet traffic with a VPN so that hackers cannot steal your personal data.
The Preferred Way to Stay Connected When Traveling in St Lucia
Getting a SIM card from Digicel would do you well when considering a Saint Lucian SIM card.
