Bordersim does not offer eSIM plans for Madagascar that include a phone number or SMS capability. Travelers will only find data‑only eSIM options from this provider for the country. However, VoIP applications such as WhatsApp, Telegram, and iMessage can typically be used over the data connection to make calls and send messages, although some destinations may block or restrict certain services. It is advisable to confirm that the specific apps you need are accessible in Madagascar before purchasing a plan.
