The Pick: 10GB at $8.56
#1 RecommendationThe 10GB plan costs $8.56 in the HelloRoam catalogue and connects to Orange's 5G network. Per-GB rate: $0.86/GB. That is the only per-destination price feed this site holds, so it is the only destination price we quote.
On plan shape and our published rubric, HelloRoam is the best fit of the 5 providers we score for a trip this size. Its own published entry rate is $3.50/GB, and it rates 8.7/10.
Who this plan fits
Travelers staying 7 days who use maps, messaging, and social media. Your daily usage sits around 1.5GB, totaling 11GB for the trip.
Why this plan
Trip-length match

Provider score breakdown
HelloRoam scores 22.3 of 25 across the 5 rubric dimensions for Saint Martin. 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
Orange is the single operator on the published Saint Martin list. That list is what HelloRoam publishes for Saint Martin, captured on 17 August 2026. A second operator on the list is a fallback when the first has no bars, which is the whole practical difference the count makes.
Plan recommendation by usage tier
Each tier maps to a specific plan and provider for Saint Martin.
Light user
Maps + messagingLight travelers in Saint Martin (maps, messaging, email) use 4GB over 7 days at 0.5GB/day. HelloRoam's 5GB plan at $4.93 ($0.99/GB) covers the trip, and the local 5G network carries it. That price is from the Saint Martin catalogue. On our tier match, HelloRoam takes Light at 86 out of 100. Its published entry rate is $3.50/GB. The trade-off: it does not sell a bundle that crosses borders, which Airalo does.
Moderate user
Social + browsingModerate-use verdict for Saint Martin: 11GB over 7 days handles social feeds, navigation and daily browsing on a local network. HelloRoam prices the 20GB tier here at $18.64 ($0.93/GB). Holafly scores highest at this tier, 96 out of 100. Limitation: no per-GB tier, so light users pay for data they will not use.
Heavy user
Streaming + callsHeavy-use verdict for Saint Martin: 21GB over 7 days at 3GB/day. Unlimited runs $2.36/day on the Saint Martin catalogue. Commit to 30 days there and the rate drops to $1.94/day, 18% off. Holafly scores 96 out of 100 at this tier. Limitation: no per-GB tier, so light users pay for data they will not use.
Your Saint Martin 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 Martin weekend uses 5GB for moderate travelers. Grab the 5GB plan at $4.93 ($0.99/GB). Per-GB rates reward big bundles, but a weekend cannot use one. Smallest sufficient plan wins. Light weekend users (email and maps) fit the 1GB plan at $1.14.
Vacation (7-14 days)
A 10-day vacation in Saint Martin 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 $18.64 covers the trip, and the local 5G network carries it. Vacationers who stream or video-call family can switch to unlimited at $2.36/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 Martin (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 $2.36/day is the safe pick for corporate travel. Total: $11.80 for 5 days on the local 5G network.
Backpacking (10-30 days)
Backpacking through Saint Martin (14+ days): 12GB at 0.8GB/day for maps, hostel apps, and messaging. The 20GB plan at $18.64 ($0.93/GB) fits budget travelers on the local 5G network. Ultra-light backpackers (email and maps only) start with 1GB at $1.14. The single biggest saving on a long route is offline maps, pulled down on WiFi before you leave town.
Your Saint Martin provider comparison
Which eSIM provider fits your Saint Martin trip? The answer depends on your usage tier, trip length, and priorities. If your Saint Martin trip is one leg of several, Airalo is built for it: 200 published destinations and continent-scale bundles. Single-country travelers pay for reach they will not use, at a published $4.50/GB, and get 14 days of refund cover. 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 Martin unlimited rate we hold, $2.36/day, is HelloRoam's own. Saily ships NordVPN inside every plan from $3.99/GB. It encrypts all traffic without a separate app install. The trade-off is reachability: support is email in 1 language, with no round-the-clock hours, and the refund window closes at 30 days. Nomad wins one thing outright, and it is the thing most buyers check first: $3.00/GB, the lowest published fixed rate of the 5. Everything else is thin. One plan shape, 200 destinations, a 30-day refund window, and support that is email in 2 languages, with no round-the-clock hours. HelloRoam runs on 204+ carrier partners across 186 destinations. Fixed plans start at $3.50/GB, second only to Nomad among fixed rates. The 180-day refund window on unactivated eSIMs is the longest here, tied with Holafly. HelloRoam support is live chat, WhatsApp and email in 63 languages, around the clock. Trade-off: no regional multi-country bundles yet, and Airalo publishes 14 more destinations.
Why the rubric leader finishes first
HelloRoam tops the rubric for Saint Martin at 8.7 out of 10, computed the same way for all 5. The case for it is what happens when a plan does not fit: 180 days to refund an unactivated eSIM, and support you can reach, live chat, WhatsApp and email in 63 languages, around the clock. The case against it is reach and price. Airalo covers 200 destinations and sells regional bundles HelloRoam does not. Nomad starts at $3.00/GB. Both of those are real wins and neither is ours.
Alternative options
Different traveler profiles need different plans. Here are runner-ups for each use case.
1GB at $1.14
Entry-level plan at $1.14 for travelers who use data sparingly. Maps, email, and messaging only. Upgrade mid-trip if you need more.
20GB at $18.64
The 20GB tier handles 7 days of heavy use at 3GB/day. Best for digital nomads and business travelers who run video calls daily. Costs $0.93/GB.
Unlimited at $2.36/day
No data cap at $2.36 per day on a local network. Costs less than the 20GB fixed plan after 8 days. Skip the GB math entirely.
| Days | Price | Per day | Discount |
|---|---|---|---|
| 1 | $2.27 | $2.27/day | 4% |
| 3 | $6.51 | $2.17/day | 8% |

| 14 | $29.41 | $2.10/day | 11% |
| 30 | $58.06 | $1.94/day | 18% |

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 |
| Moderate | 1.5 | 11 GB | The above plus social feeds and browsing |
| Heavy | 3 | 21 GB | Streaming, video calls, laptop hotspot |
HelloRoam sizes a Saint Martin plan against those three bands and nothing else. A 7-day trip runs 4 GB on the light band, 11 GB on the moderate one and 21 GB on the heavy one, so the gap between the cheapest and the safest tier is 17 GB of headroom. Pick the band your phone habits already sit in at home.
Your calibrated Saint Martin data budget
Your Saint Martin data budget depends on more than usage habits. Local conditions shift the number up or down. Adjusted daily estimate: 1.5GB/day (down from the 1.5GB baseline). Over 7 days: 11GB total on a local network. The 20GB plan at $18.64 ($0.93/GB) covers this adjusted budget.

What plan do I need?
For 7 days in Saint Martin, you need between 1GB (light use) and 25GB (heavy use). The 3GB plan at $3.20 covers most travelers at $0.46/day on a local network. HelloRoam matches that shape and publishes an entry rate of $3.50/GB.
Best plan for 7 days?
For 7 days in Saint Martin, the best eSIM depends on usage. The fixed 20GB at $18.64 covers 11GB on a local network. Unlimited runs $2.36/day here ($16.52 total), which is cheaper for heavy users. Both figures are catalogue prices. Moderate users save on the fixed tier at $0.93/GB.
How much data do I need?
You need between 1GB and 25GB for 7 days in Saint Martin. Light users (maps and chat) should get the 1GB tier at $1.14. Most travelers fit the 3GB at $3.20 for social media, navigation, and messaging on a local network. Those are catalogue prices; HelloRoam fits the shape best of the 5 we score. WiFi in Saint Martin is available at hotels and some restaurants, offsetting about 10% of usage.
Which provider is cheapest?
Saint Martin eSIM prices start at $1.14 for 1GB ($1.14/GB) on the catalogue, the only per-destination feed we hold. Larger plans drop the rate: 20GB costs $18.64 ($0.93/GB). On published floors, Nomad is cheapest at $3.00/GB, though it quotes no Saint Martin figure. All plans connect to Orange.
Is an eSIM worth it?
An eSIM is worth it for Saint Martin. WiFi in Saint Martin covers hotels and some public areas, but an eSIM keeps you connected everywhere. The 20GB plan at $18.64 gives you 11GB on a local network for 7 days. That is $91.36 less than carrier roaming.
eSIM vs SIM card?
Use both in Saint Martin: keep your home SIM for calls and add an eSIM for data. Saint Martin eSIM plans start at $1.14 for 1GB on a local network, a catalogue price. That avoids the 15-30 minutes airport SIM queue and the $15-25 counter price.

Which eSIM provider is best for Saint Martin?
HelloRoam scores 22.3 of 25 for Saint Martin across per-GB value, plan flexibility, buyer protection, support access, and destination reach, which is first of the five on this site's weighting. 180-day refund window on unactivated eSIMs, tied for the longest.

Can I switch plans mid-trip in Saint Martin?
Yes. Buy a second eSIM through the provider app while in Saint Martin. Most phones support 8+ eSIM profiles. Delete the expired plan to free a slot. You do not lose your home number.
Should I buy a Saint Martin eSIM or a regional bundle?
A single-country plan at $0.86/GB beats regional pricing for Saint Martin-only trips. Multi-country routes through Caribbean save with the Airalo Americas bundle.
How far in advance should I buy my Saint Martin eSIM?
Buy 1 to 3 days before departure. Install the QR code over WiFi at home. The validity timer starts at first network connection in Saint Martin, not at purchase. This gives you time to troubleshoot any installation issues before your flight.
Is the 10GB plan enough for streaming in Saint Martin?
Streaming puts a traveler on the published 3 GB heavy band. Over 7 days that is 21GB. The 10GB plan falls short for daily streaming. Heavy streamers should consider 20GB or unlimited at $2.36/day.
What network does my Saint Martin eSIM connect to?
Orange is the single operator on the published Saint Martin list. The published list carries the 5G capability label, and it does not record which operator a given handset selects. Save offline maps for Saint Martin before you fly.
