SimOptions provides several eSIM plans for Martinique that include a phone number and voice capability. Prices range from $23.90 USD for the Travel Basic+ plan, which offers 20 GB of data and 15 days of validity, up to $55.90 USD for the My European eSIM 120 GB plan, which provides 120 GB of data for 30 days. All of these plans use a +33 dialing code, giving you a French phone number that works in Martinique and across the 40+ countries covered by the eSIM. Both inbound and outbound calls are supported, but the dataset does not list any SMS functionality, so no text messaging is included.
If you require SMS capabilities, or need a local Martinique number, you should confirm the details directly with SimOptions before purchasing. They can confirm whether any of their plans have been updated to include SMS or whether an alternative provider might better suit your needs.
