For a 7-day trip with moderate WiFi availability, a 5GB fixed plan covers light-to-moderate usage comfortably. Heavy users should consider Holafly's unlimited daily plan at $3.49/day. WiFi at hotels and cafes in Sint Maarten reduces cellular consumption by 30-60% depending on usage patterns.
Can I add more data mid-trip in Sint Maarten?
Airalo supports in-app top-ups for Sint Maarten — purchase additional data without installing a new eSIM. Holafly's unlimited plan eliminates top-up need entirely. Saily requires a new eSIM purchase for more data. Nomad also requires a separate purchase. Top-ups need an internet connection: WiFi (moderate availability in Sint Maarten) or remaining cellular data. Buy top-ups before your current plan runs out to avoid being offline in Sint Maarten while trying to purchase more data.
When should I activate my eSIM for Sint Maarten?
Install your Sint Maarten eSIM 24-48 hours before departure while you have stable WiFi. Do not enable data roaming until you land. Most providers start the plan validity clock at first data use, not at installation. Airalo and Holafly both confirm this policy for Sint Maarten. Saily and Nomad start validity on first connection. Install early to troubleshoot any QR scanning issues while you still have home internet. Enable data roaming in Sint Maarten only after landing and clearing customs.
How do I set up dual SIM for Sint Maarten?
Set your travel eSIM as the data line and keep your home SIM for calls and texts. On iPhone: Settings > Cellular > select the Sint Maarten eSIM line > Turn On This Line > set as Cellular Data. On Android: Settings > Network > SIM Manager > set eSIM as mobile data. Disable Data Roaming on your home SIM to prevent charges. Enable Data Roaming on the Sint Maarten eSIM only. All four providers — Airalo, Holafly, Saily, Nomad — work in dual SIM mode.
Do all providers have the same speed in Sint Maarten?
All four providers deliver nearly identical speeds in Sint Maarten — standard 4G LTE speeds — because they route through the same TelCell infrastructure. eSIM providers do not own towers; they lease capacity from Sint Maarten's carriers. Speed differences between Airalo, Holafly, Saily, and Nomad are negligible under normal conditions. Peak-hour congestion in Sint Maarten cities affects all providers equally. Our Speed dimension (20% weight) scores them within 0.2 points of each other for most destinations.

Airalo leads with a 4.9/5 app store rating — the highest among the four providers.

Holafly scores 4.4/5 with reliable auto-APN configuration for Sint Maarten. Nomad scores 3.9/5 — functional but relies on email-delivered QR codes rather than in-app installation. App quality carries 15% weight in our scoring matrix because a clunky install process can delay connectivity on arrival.
Can I tether/hotspot with a travel eSIM in Sint Maarten?
Most travel eSIMs support hotspot tethering in Sint Maarten. Airalo allows hotspot on all plans. Holafly allows it but some unlimited plans may have fair-use tethering policies. Saily and Nomad support hotspot with no documented restrictions. Expect 3-5x faster data consumption when hotspotting — a connected laptop syncs email, updates apps, and loads full desktop sites. A 5GB plan lasts roughly 2-3 days with active hotspot use in Sint Maarten. Battery drain increases 30-40%.

Airalo activates entirely within its app. Holafly delivers QR codes by email and app; activation connects to TelCell automatically on arrival.

Saily and Nomad both offer 30-day refund windows for unused eSIM profiles. Airalo provides a 14-day refund period. All four require the plan to be unused — no data consumed — to qualify. If you have already activated and used data in Sint Maarten, refunds are at provider discretion.

eSIM transfer between devices depends on the provider, not the country. Airalo supports re-downloading an unactivated eSIM profile on a new device. Holafly, Saily, and Nomad generally allow one installation per purchase — contact support before activating on the new device. Apple's eSIM Transfer feature (iPhone-to-iPhone via cable or iCloud) does not apply to third-party travel eSIMs. Always install your Sint Maarten eSIM before factory-resetting or trading in your phone.
