BetterRoaming does not provide any eSIM plans for Saint Barthélemy that include a phone number or SMS capability. All of the available plans are data‑only, so travelers will not receive inbound or outbound calls or text messages from the eSIM itself.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but some destinations may block or restrict access to specific apps or services. It is advisable to verify that the VoIP applications you rely on are accessible in Saint Barthélemy before purchasing an eSIM from BetterRoaming.
