BetterRoaming does not provide an eSIM for Mauritius that includes a local phone number or SMS capability. Travelers can purchase a data‑only plan from BetterRoaming to stay connected, and can use VoIP apps such as WhatsApp, Telegram, or iMessage over that data connection for calls and messaging. However, some destinations might block or restrict access to specific apps or VoIP services, so users should confirm that the applications they rely on are available in Mauritius before purchasing the plan.
