Yes, simpleSIM sells a Martinique eSIM that includes a phone number and SMS support. The plan is priced at $39.14 USD, gives 20 GB of data, and is valid for 30 days. Its phone number carries the dialing code +33, which is the national code for France rather than the local Martinique code (+590), so it is not a local Martinique number. The telephony features allow both inbound and outbound voice calls and inbound and outbound SMS, and the plan also supports tethering. Travelers who need specific dialing or messaging arrangements should confirm the details directly with simpleSIM.
