Provider score breakdown
HelloRoam scores 22.3 of 25 across the 5 rubric dimensions for Saint Barthelemy. 180-day refund window on unactivated eSIMs, tied for the longest. Support in 63 languages, more than the other four combined. The main trade-off: regional multi-country bundles are not available yet.
Network routing
The published attachment list for Saint Barthelemy holds one operator, Orange. The dataset records operator names and capability labels for Saint Barthelemy and nothing else: no throughput figure, and no statement of which operator a handset settles on. Plan the tier by trip length, not by the operator count.
Plan recommendation by usage tier
Each tier maps to a specific plan and provider for Saint Barthelemy.
Light user
Maps + messagingIf you only check maps and send messages in Saint Barthelemy, budget 4GB for 7 days. The catalogue prices the 5GB tier at $22.66 on a local mobile network. HelloRoam scores 86 out of 100 at this tier, the highest of the 5 we score, on plan shape and cost per gigabyte at 0.5GB a day. Support there is live chat, WhatsApp and email in 63 languages, around the clock.
Moderate user
Social + browsingModerate-use verdict for Saint Barthelemy: 11GB over 7 days handles social feeds, navigation and daily browsing on a local mobile network. HelloRoam prices the 20GB tier here at $43.34 ($2.17/GB). Holafly scores highest at this tier, 96 out of 100. Limitation: there is no small plan to fall back on, so under a gigabyte a day you overpay.
Heavy user
Streaming + callsHeavy travelers in Saint Barthelemy (streaming, video calls, hotspot) use 21GB and up over 7 days at 3GB/day. Unlimited daily data runs $5.89/day in the Saint Barthelemy catalogue, $41.23 for 7 days. Holafly takes the Heavy tier at 96 out of 100, on a published $2.99/day. The trade-off: there is no small plan to fall back on, so under a gigabyte a day you overpay.
Your Saint Barthelemy trip type, matched to a plan
Weekend, vacation, business, or backpacking. Each trip profile maps to a different plan.
Weekend (2-3 days)
A 2-3 day Saint Barthelemy weekend uses 5GB for moderate travelers. Grab the 5GB plan at $22.66 ($4.53/GB). Short stays favor the smallest plan that covers your needs. Per-GB efficiency matters less than avoiding waste. Light weekend users (email and maps) fit the 1GB plan at $5.70.
Vacation (7-14 days)
A 10-day vacation in Saint Barthelemy hits 15GB at moderate use. Social photo sharing moves the day from the 0.5 GB light band to the 1.5 GB moderate one. HelloRoam's 20GB plan at $43.34 covers the trip, and a local 5G network carries it. Vacationers who stream or video-call family can switch to unlimited at $5.89/day instead. Pre-download restaurant guides and city maps on WiFi to hold the day on the light band.
Business (3-7 days)
Business trip to Saint Barthelemy (5 days): 15GB on the published 3 GB heavy band, which is what video calls, email sync and ride-hailing add up to. Unlimited at $5.89/day is the safe pick for corporate travel. Total: $29.45 for 5 days on a local 5G network.
Backpacking (10-30 days)
Backpacking through Saint Barthelemy (14+ days): 12GB at 0.8GB/day for maps, hostel apps, and messaging. The 20GB plan at $43.34 ($2.17/GB) fits budget travelers on a local 5G network. Ultra-light backpackers (email and maps only) start with 1GB at $5.70. Rural stretches burn data on navigation alone, so download the maps while you still have WiFi.
Your Saint Barthelemy provider comparison
Five providers compete for Saint Barthelemy travelers. Here is how each one stacks up against the country's specific conditions. Buy Airalo for a route rather than a destination. It publishes 200 destinations and the only fully published regional-bundle shape here, spanning 16 to 130 countries on one profile. The cost of that reach is the highest published floor of the five, $4.50/GB, and a refund window that shuts after 14 days. Holafly publishes unlimited daily from $2.99/day and ties HelloRoam on the longest refund window at 180 days. Heavy data users skip the arithmetic entirely. Limitation: a 1GB/day tethering cap, post-threshold throttling, and no fixed tier, so light and moderate travelers overpay. The Saint Barthelemy unlimited rate we hold, $5.89/day, is HelloRoam's own. Saily is the one provider here whose plan ships with a VPN, from Nord Security, at no extra charge and from a published $3.99/GB. On hotel and airport WiFi it is one fewer subscription to manage. Support, though, is email in 1 language, with no round-the-clock hours. Nomad is the budget answer: a published $3.00/GB, no account needed, quick checkout. The rubric still leaves it in the bottom half, because it sells one shape, publishes no regional bundle and answers by email alone. Buy it when cost is the only thing you are optimising. HelloRoam tops our rubric on the two dimensions that matter once a plan turns out wrong: 180 days to refund an unactivated eSIM, and support that is live chat, WhatsApp and email in 63 languages, around the clock. It wins neither price nor reach. Nomad's floor is lower at $3.00/GB, and Airalo's destination list is 14 longer.
Why the rubric leader finishes first
HelloRoam finishes first on our published rubric at 8.7 out of 10, and the margin is thin. HelloRoam wins support access outright, live chat, WhatsApp and email in 63 languages, around the clock. It ties the longest refund window at 180 days on an unactivated eSIM. Where it loses: Airalo publishes 200 destinations against 186, and Nomad publishes a cheaper fixed floor at $3.00/GB against $3.50/GB. Saint Barthelemy itself runs on a local 5G network whoever you buy from.

Different traveler profiles need different plans. Here are runner-ups for each use case.
1GB at $5.70

Published daily bands for a 7-day trip
| Band | GB per day | 7-day total | What it covers |
|---|---|---|---|
| Light | 0.5 | 4 GB | Maps, messaging, boarding passes |

| Heavy | 3 | 21 GB | Streaming, video calls, laptop hotspot |
HelloRoam sizes a Saint Barthelemy plan against those three bands and nothing else.
