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

Yes, travel eSIM plans that include a phone number and SMS are available for Saint Martin. Earth Esim, eSimfly, Roamify and Orange Travel each offer data‑rich plans (from 20 GB to 35 GB) that last 30 days and start around $24 USD and go up to about $38 USD. All of these plans provide inbound and outbound voice and SMS using overseas dialing codes: Earth Esim and Roamify use +33 (France) and Orange Travel lists 33; eSimfly offers +44 (United Kingdom). Because Saint Martin’s local dialing code is +1, the phone numbers supplied by these plans are foreign, not local, yet they function for calls and text messages wherever GSM coverage is available.

If a local +1 number is required you may need to search for a different provider. Otherwise, you can still use any of the listed eSIMs and rely on VoIP applications such as WhatsApp, Telegram or iMessage to make voice calls or send messages over the data connection.
