Frequently Asked Questions

Everything you need to know about your Saint Martin (French part) eSIM

It connects to Dauphin Telecom (4G B1, B3, B20) and Orange Caraïbes (4G B1, B3, B7, B20). Coverage is limited to populated coastal areas; mountainous interior has reduced or no service. 3G (UMTS B1) remains active on both networks as a fallback.

Band 20 is used by both Dauphin and Orange for 4G coverage, especially in valleys and indoors. Phones from regions like the US or Asia that omit band 20 may see weaker signal or drop to 3G in those areas. Always check your phone’s band support.

No. The eSIM works only in the French territory of Saint Martin. It will not connect in the Dutch side (Sint Maarten) or neighbouring Anguilla. Service stops at the border and you would need a separate eSIM for those areas.

There are no known blocks or throttling beyond standard operator traffic management. VPNs, video streaming, and VoIP should work normally. However, speeds depend on network congestion and local signal conditions in populated coastal areas.

Visitors are often surprised that coverage in the mountainous interior is very poor or nonexistent even though the island is small. Service is reliable only in coastal towns and along main roads. Plan to download maps and messages before heading inland.

Compare 1 GB / 7 days, 2 GB / 15 days and 10 GB or more / 30 days. Use the shorter profiles for lighter maps and messaging use, then compare the larger allowance for streaming, video calls or work apps.

The start rule is product-specific. Review the selected plan details before installing it so you know whether any action is required before arrival.
