Voyasim does not provide a Madagascar eSIM that includes a phone number or SMS capability. Only data‑only plans are available from this provider in Madagascar.
Travelers who need to communicate can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable to confirm that the apps you rely on are accessible in Madagascar before purchasing an eSIM.
