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

Travel eSIM plans with phone number and SMS support are available for the French part of Saint Martin. Providers include Earth Esim, which offers the Orange Global eSIM, and Roamify, which has two options: a 20 GB plan and a 35 GB plan. All these plans include a phone number, inbound and outbound voice and SMS, and a 30‑day validity period. The phone numbers use foreign dialing codes; Earth Esim and the Roamify 20 GB plan use +33 from France, while Roamify’s 35 GB plan uses +44 from the United Kingdom, so they are not local Saint Martin numbers. Prices run from $24 to $35 USD, with data caps between 20 GB and 51 GB. If a local Saint Martin number is preferred, users can still use data‑only eSIMs and send calls or messages via VoIP applications such as WhatsApp, Telegram, or iMessage.
