Heavy use, 10 GB and up
Streaming and video calls · A full remote work day · Laptop hotspot
Video calls and a laptop hotspot in Saint Barthelemy? Holafly wins this tier 96 to 66, with HelloRoam second. Nobody beats its $1.00 a gigabyte at 3 GB a day. HelloRoam finishes on 66 and loses the tier. No daily-unlimited plan exists at Saily and Nomad, so a heavy trip is one large purchase. A 10 GB plan for Saint Barthelemy runs $32.56, and unlimited runs $5.89 a day.

How to read the rate column: it is each provider's own published entry price, converted to a per-gigabyte figure at the daily usage for that tier. Without that conversion a daily plan and a per-GB plan cannot be compared at all. Published entry rates: Airalo $4.50/GB, Saily $3.99/GB, Holafly $2.99/day, Nomad $3.00/GB, HelloRoam $3.50/GB. Those are catalogue floors, not prices for Saint Barthelemy. Destination prices above are HelloRoam catalogue prices, because HelloRoam's catalogue is the only per-destination feed this site reads. For the other four we have a published floor and no Saint Barthelemy figure we would stand behind, so none is shown.
How trip length changes your Saint Barthelemy plan
Short trips and extended stays need different data strategies. Find your trip length below.
Short trip (1-3 days)
A 1-3 day trip needs 5GB at moderate use. The 5GB plan at $22.66 covers maps and messaging on a local mobile network.
Standard trip (5-10 days)
For a week-long visit, 11GB covers moderate daily use. The 20GB at $43.34 on a local mobile network fits this range.
Extended stay (14-30 days)
For stays of 14+ days, unlimited data at $5.89/day on a local mobile network beats buying multiple fixed plans.
Your Saint Barthelemy shortlist, all 5 providers

Who you're connecting to
In Saint Barthelemy, the underlying carrier matters more than the brand on your plan.
The carrier your eSIM connects to in Saint Barthelemy shapes speed, coverage, and value. Most of Saint Barthelemy's 5G capacity sits with Orange, concentrated where visitors actually go. Which of the five you buy from does not change those towers. It changes what you can buy and what happens if the plan does not fit. Crossing more than one border on this trip? Airalo is the only one of the five publishing a regional bundle, from 16 to 130 countries on a single profile. Reach costs it price: a published $4.50/GB, the dearest floor here. Burning 3 GB a day on video calls? Holafly is the only provider of the five publishing unlimited daily across its catalogue, from $2.99/day. Light users pay for data they will not use. If you work from cafes in Saint Barthelemy, Saily's VPN layer encrypts traffic without a second app. Plans start at $3.99/GB and Saily support runs in 1 language, by email only. Nomad's $3.00/GB is the cheapest published fixed rate here. Support is email in two languages, and coverage stops at 200 destinations. HelloRoam runs on 204+ carrier partners across 186 destinations, refunds an unactivated eSIM for 180 days and answers in 63 languages around the clock. Fixed plans start at $3.50/GB, above Nomad's floor. All 1 operator in Saint Barthelemy support 5G, so the plan size matters more than the carrier preference.
HelloRoam publishes its local operator list for Saint Barthelemy, and the next section prints that list in full. The other four providers publish no equivalent list, so the cards below carry published facts about each provider instead of a carrier we would be guessing at.

What uses your data in Saint Barthelemy
Activity-level data breakdown for a Saint Barthelemy trip.
Streaming
Streaming moves a traveler into the heavy band, which the published benchmark puts at 3 GB a day. 7 days in Saint Barthelemy at that rate comes to 21 GB, and the 20GB plan at $43.34 is the smallest Saint Barthelemy tier that clears it. Downloading episodes over hotel WiFi keeps the day inside the 1.5 GB moderate band instead.
Navigation
Navigation alone keeps a Saint Barthelemy trip on the 0.5 GB light band. That is 4 GB across 7 days, which the 5GB plan at $22.66 covers. Save the Saint Barthelemy map region over WiFi before you fly and the same trip draws less.
Social media
The moderate benchmark is 1.5 GB a day, which is what social apps plus messaging draw. Across 7 days in Saint Barthelemy that is 11 GB. The 20GB plan at $43.34 covers the trip.
Work tools
Remote work in Saint Barthelemy sits on the 3 GB heavy band once video calls start. 21 GB covers 7 days. The 20GB plan at $43.34 is the matching tier, and a laptop hotspot keeps it there rather than below it.
Your Saint Barthelemy pricing notes
How much does an eSIM cost in Saint Barthelemy? Plans start at $5.70 for 1GB and go up to $43.34 for 20GB. Full pricing: 1GB at $5.70 ($5.70/GB), 3GB at $16.00 ($5.33/GB), 5GB at $22.66 ($4.53/GB), 10GB at $32.56 ($3.26/GB), 20GB at $43.34 ($2.17/GB). Moderate users get the best value at 5GB for $22.66 ($4.53/GB), which covers a 4-day trip at 1.5GB/day. Short-trip travelers spending 3-4 days in Saint Barthelemy pick 1GB at $5.70 and pay only for the data they need. If your trip runs longer than 7 days, unlimited data at $5.89/day costs less than the 20GB fixed plan at $43.34. A 30-day unlimited plan drops to $4.83/day (18% off). The split is simple: Holafly sells unlimited days from $2.99/day, Nomad sells the cheapest published gigabyte at $3.00/GB, and your daily usage decides which is cheaper. Light users in Saint Barthelemy start at $5.70 for 1GB on the catalogue. Nomad advertises a lower floor, $3.00/GB, but publishes no Saint Barthelemy price.

Common Saint Barthelemy eSIM questions
Direct answers grounded in real plan data and carrier coverage.
What plan do I need?
Most travelers to Saint Barthelemy need a 3GB eSIM plan. That covers 3GB over 7 days for social media, maps, and messaging. The catalogue prices that tier at $16.00 ($5.33/GB) on a local mobile network. Light users save with 1GB at $5.70. Heavy users should consider 20GB at $43.34. HelloRoam fits this trip shape best of the 5 providers we score, at a published $3.50/GB.
How much data do I need?
For a 7-day trip to Saint Barthelemy, your data needs depend on activity. Maps and messaging use about 0.09GB a day, 1GB across the trip. Social media and navigation use 0.4GB a day, 3GB in total. Streaming and video calls run 3.53GB a day, 25GB. WiFi in Saint Barthelemy is available at hotels and some restaurants, offsetting about 10% of usage. Saint Barthelemy plans start at $5.70 on the catalogue.
Which provider is cheapest?
Nomad publishes the lowest fixed eSIM rate of the 5 providers we score, at $3.00/GB. The cheapest Saint Barthelemy plan in our price feed is 1GB at $5.70 on a local mobile network, a catalogue price. Published entry rates: HelloRoam from $3.50/GB, Holafly from $2.99/day, Airalo from $4.50/GB, Nomad from $3.00/GB, Saily from $3.99/GB. Those are catalogue floors, not Saint Barthelemy quotes. For a 7-day trip needing 11GB, compare the total cost, not the headline rate.
Is an eSIM worth it?
An eSIM saves money and time in Saint Barthelemy. Airport SIM cards cost $15-25 after a 15-30 minutes wait. A 20GB eSIM costs $43.34 for 11GB and activates before you board. It runs on a local mobile network, the same network airport SIMs use. On published plan shape and our rubric, HelloRoam is the closest fit of the 5, and its own entry rate is $3.50/GB.
eSIM vs SIM card?
Use both in Saint Barthelemy: keep your home SIM for calls and add an eSIM for data. Saint Barthelemy eSIM plans start at $5.70 for 1GB on a local mobile network, a catalogue price. That avoids the 15-30 minutes airport SIM queue and the $15-25 counter price.
How to set up?
On iPhone (iOS 17+): Settings, Cellular, Add eSIM, scan the QR your provider sends. On Android: Settings, Network, SIMs, Add eSIM, scan or enter the activation code. The plan connects to Orange in Saint Barthelemy automatically. Saint Barthelemy plans start at $5.70 for 1GB on the catalogue.
Plan match by traveler profile

Backpacker
A backpacker heading to Saint Barthelemy should budget 7 GB for maps and messaging across 14 days. That lands on the 10 GB plan, $32.56 on a local mobile network. On published plan shape, HelloRoam is the closest fit of the five, and Airalo still reaches more places at 200.
On the 0.5 GB light band, backpackers use 4GB across 7 days. The 5GB tier at $22.66 fits that target on a local mobile network.
Business traveler
A business traveler in Saint Barthelemy needs 15 GB for video calls and uploads over 5 days. The 20 GB plan covers that at $43.34, or $2.17 per GB, on a local mobile network. HelloRoam sells the shape this trip needs; Nomad publishes the lower fixed floor.

Your questions, answered
How many gigabytes per day should I budget in Saint Barthelemy?
Budget 0.5 GB a day for maps and messaging, 1.5 GB a day for social media and browsing, and 3 GB a day if you stream. Over a 7-day Saint Barthelemy trip those rates come to 4 GB, 11 GB and 21 GB. Most visitors land on the middle rate, so the 20 GB plan at $43.34 covers the moderate figure on a local mobile network. Past 3 GB a day the fixed tiers run out here, and unlimited days at $5.89 take over. Pick the daily rate that matches your habits at home, because a trip rarely changes them.
Which plan shape fits my Saint Barthelemy trip, fixed tiers or unlimited days?
If you stream video or run work calls most days in Saint Barthelemy, take the unlimited shape at $5.89 a day. If you keep to maps, messaging and evening browsing, take a fixed tier: a 7-day trip at 1.5 GB a day needs 11 GB, which the 20 GB plan covers at $43.34. Shape availability is not the same everywhere. Unlimited days come from Holafly, catalogue-wide. HelloRoam and Airalo publish unlimited on part of the catalogue, so check the destination first. Nomad and Saily sell one shape only, a fixed bundle of gigabytes. The catch with Holafly: no per-GB tier exists, so it is unlimited or nothing.
Which eSIM plan fits a light or heavy data user in Saint Barthelemy?
Calculate your Saint Barthelemy data need by usage rate. At 0.5 GB a day for 7 days: 4 GB needed. The 5 GB plan at $22.66 covers it at $4.53/GB. At 3 GB a day for 7 days: 21 GB needed, and the 20 GB plan at $43.34 ($2.17/GB) is the largest tier sold here, so a heavy pace needs a second purchase or an unlimited plan. That is $2.36/GB less than the entry tier charges.
What should I check on my phone before I buy a Saint Barthelemy plan?
Run the check before you pay, not at the gate. Dial *#06# and look for an EID number under the IMEI, because that number is what an eSIM profile installs against. iPhones from XS onward, Samsung Galaxy from S20 onward, and Pixel from 3 onward all qualify. Confirm the phone is carrier-unlocked as well. Those checks take a minute and they decide whether a Saint Barthelemy plan works at all on 5G. Some sites write e-SIM, others write e SIM. Same profile either way.
What starts the clock on a Saint Barthelemy plan, the purchase or the landing?
Experienced travelers install at home and activate on arrival, because the timer answers to the network, not the receipt. Scanning the QR code over WiFi costs you nothing. The first Saint Barthelemy network connection opens the validity window. The 1 GB plan at $5.70 suits a short stay. The 20 GB plan at $43.34 suits a longer one. Buy 1 to 3 days before the flight so the plan is fresh, installed and tested before you leave the house.
Is Saint Barthelemy well-covered by travel eSIM networks in Caribbean?
City-focused Caribbean travelers find 5G coverage on Orange strong across tourist areas, transport hubs and centres. Travelers heading off the main routes should check the specific area before buying. Every travel eSIM taps the same local networks, so coverage inside Saint Barthelemy is not the thing that separates providers. Published destination lists differ: Airalo, Nomad and Saily at 200, HelloRoam at 186 and Holafly at 160. The 5 GB plan at $22.66 ($4.53/GB) fits a standard Caribbean visit.
Which activities use the most mobile data in Saint Barthelemy?
Streaming and video calls are the two activities that force a bigger tier in Saint Barthelemy. Both put a day on the published 3 GB heavy band. Everything else a tourist does, navigation included, sits on the 0.5 GB light band or the 1.5 GB moderate one. Downloading video over hotel WiFi keeps the trip on the lower band, and the 5 GB plan at $22.66 then covers more days.
How do I match a Saint Barthelemy plan tier to the number of nights I am staying?
The arithmetic is one line: nights multiplied by 1.5 GB a day equals the data you need. Match the result against the Saint Barthelemy tiers: 1 to 2 nights takes the 3 GB plan at $16.00 ($5.33/GB); 3 nights takes the 5 GB plan at $22.66 ($4.53/GB); 4 to 6 nights takes the 10 GB plan at $32.56 ($3.26/GB); 7 to 13 nights takes the 20 GB plan at $43.34 ($2.17/GB). Add 20% for streaming days. The 20 GB plan holds the lowest per-GB rate here at $2.17/GB. Round up rather than down at every step, since unused data costs you cents and running out costs you an evening.
How many days must I commit to for unlimited pricing in Saint Barthelemy?
You commit to at least 1 day, which costs $5.65 in Saint Barthelemy. If your trip runs longer, book the days upfront: the 30-day tier costs $4.83 a day, 18% below the $5.89 base rate. If you extend later instead, you pay the base rate for the extra days. Full 5G speed runs to 2GB a day before fair-use terms apply.
Which provider backs up a mis-sized Saint Barthelemy plan?
HelloRoam publishes the widest support access of the five we score, at 63 languages over live chat, WhatsApp and email, around the clock. HelloRoam publishes support in 63 languages, Airalo 12, Holafly 10, Nomad 2 and Saily 1. Language matters more than it sounds when a plan is wrong in a country you have not been to before. On refunds: HelloRoam and Holafly publish 180 days, Nomad and Saily 30 days and Airalo 14 days, all measured on an unactivated eSIM. Buy the size you need in Saint Barthelemy, then keep the receipt until the profile is live. Sizing up first is still cheaper than any refund: the 20 GB plan holds the lowest rate here at $2.17/GB.
