Yes, Simbye offers eSIM plans for Saint Martin that include a phone number and SMS. The available plans provide a French phone number with the dialing code +33 and allow both inbound and outbound calls and SMS messages. Prices range from $31.99 USD for 20 GB to $59.99 USD for 100 GB, and each plan is valid for 30 days. The phone number is a French number, not a local Saint Martin number, so users should confirm with Simbye if they need a local number or specific call and SMS features.
