2 Best Prepaid SIM Cards in St Lucia: Buying Guide

Saint Lucia (St Lucia) – known for its beaches, lovely weather, and stunning landscaped. It is also the Caribbean nation that has 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, St 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 St Lucian SIM card for 15 XCD (5.55 USD) from Digicel. Flow hands out SIM cards for free. A plan with 3 GB of data valid for 7 days will cost you 25 XCD (9.25 USD).

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 St 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.

Buying a SIM Card in Saint Lucia Guide (logos of Digicel & Flow)

Table of Contents

Can You Buy a SIM Card in St Lucia?

You can purchase a St Lucian SIM card regardless of your residence or visitor status, meaning that tourists are also allowed to buy a SIM card in St Lucia.

You do need to ensure your SIM card is registered in your name, have a phone that supports St Lucia's frequencies, and have an unlocked device (SIM-lock-free).

Where Can You Buy a SIM Card in St Lucia?

You can get a St Lucian SIM card in the official stores of Digicel and Flow and partner stores.

It is not possible to buy a SIM card at Hewanorra International Airport nor at George F. L. Charles Airport (Vigie Airport).

You can expect to pay the following for St 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 its 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, and 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, and 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 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 would want to go with Flow St Lucia. It supports traditional American Frequencies on 2G, 3G, and 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 would 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 either Flow St Lucia or Digicel St Lucia, 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 network operators:

  • 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.

5G NR in St Lucia

5G is not available in St Lucia as of 2021, and the St 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 has attractive plans. Flow can faster since the introduction of LTE-A, reaching speeds up to 200 Mbps. However, its 4G/LTE availability is lacking, let alone its LTE-A availability.

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

Saint Lucia Flag

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 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 Grenada 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%.

In terms of speeds, you should not have high hopes when in St Lucia. Even though speeds may be advertised as reaching up to 100 Mbps with Digicel and even 200 Mbps with Flow, you will rarely hit those speeds – if at all.

Instead, speeds will hover around 10 Mbps to 30 Mbps. Not blazing fast, that is for sure, but St Lucia is an island nation. There are plenty of other island nations where the cost of data is criminally high, and the speeds are to cry for.

Overall, with low costs for SIM cards and data, extensive nationwide coverage, and decent speeds, you should have a great network experience in St Lucia.

Currency in St Lucia

East Caribbean Dollar Notes (5, 10, 20, 50 & 100)

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.

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 St Lucian SIM card – you will be saving a lot of money when you do so.

However, for some, getting a St Lucian SIM card is not an option. For example, your device may be SIM-locked, meaning that you cannot use any SIM card other than the SIM card provided by your 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 two local 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.

International roaming has its pros and cons. However, it is important to know how it works. This in-depth guide explains it all.

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 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 St Lucian SIM card.
