yaySIM does not offer eSIM plans for Mauritius that include a phone number or SMS capability. The only plans that are available are data‑only eSIMs, which provide internet connectivity but no local voice or text messaging services.
Travelers who need to make calls or send messages can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, it is advisable to confirm that these apps are accessible in Mauritius before purchasing, as some destinations may block or restrict VoIP services.
