Zwitchy only provides data‑only eSIM plans for Mali, so a local phone number and SMS service are not available. If you need to make calls or send text messages, you would need to use internet‑based VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Some destinations may block or restrict access to these apps, so travelers should confirm that the services they rely on are usable in Mali before buying a plan.
