AloSIM does not provide eSIM plans for Saint Barthélemy that include a phone number or SMS capability. All available offerings are data-only, so travelers cannot make or receive standard voice calls or SMS messages directly through their device’s native telephony functions.
Telephony can still be accessed via VoIP applications such as WhatsApp, Telegram and iMessage, which work over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so travelers should verify that the applications they rely on remain accessible in Saint Barthélemy before purchasing a data plan.
