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

Travel eSIM plans that include a phone number and SMS support for Saint Martin are offered by Roamify. Two options are available: a 20 GB plan for 30 days costing $30.00 and a 35 GB plan for 30 days costing $35.00. Both plans provide inbound and outbound voice calls and SMS, and allow tethering. The phone numbers that come with the plans use the dialing codes +33 and +44, which are foreign to Saint Martin, and therefore the numbers are not local Saint Martin numbers.

If a local Saint Martin number is required, travelers can instead use a data‑only eSIM and make calls or send messages through VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.
