Skyalo does not offer a Madagascar eSIM that includes a phone number or SMS capability. All plans available from this provider for Madagascar are data‑only, so users cannot receive or send traditional SMS or make voice calls with a local number. Over the data connection, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used for voice and messaging. However, some destinations may block or restrict access to specific VoIP services, so travelers should verify that the apps they rely on are accessible in Madagascar before purchasing.
