Can I get a travel eSIM with a phone number and SMS for Saint Martin?

Yes, travel eSIM plans that include a phone number, voice calls and SMS are available for Saint Martin. Providers such as EtravelSIM, Airhub, LineCast Networks, Simbye, eSimfly, Roamify, Orange Travel and Global Starlink offer 30‑day plans with data caps ranging from 20 GB to 35 GB, with prices starting around $27.99 USD. Each of these plans supplies an international phone number that can receive and make calls and send and receive SMS.

All of the phone numbers come with the international dialing code +33, which is the code for France. Consequently, the phone numbers are French numbers and not local Saint Martin numbers (the French part of Saint Martin uses +1 in the North American numbering plan). If a local number is required, travelers may need to look for a different solution, but the plans listed above do provide phonetic and SMS functionality over data and use a French dialing code.
