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

Travel eSIMs that include a phone number and SMS capability are available for Saint Martin. Roamify offers two plans that provide inbound and outbound voice and SMS; however, the phone numbers belong to foreign dialing codes, not the local Saint Martin code. One plan uses the French dialing code +33 and the other the United Kingdom dialing code +44, so neither provides a local Saint Martin number. Both plans are valid for 30 days, support 5G, 4G, and LTE coverage, and allow tethering. Prices start at $30.00 USD for the 20 GB plan and $35.00 USD for the 35 GB plan.
