iRoamly does not offer an eSIM for Mauritius that includes a phone number or SMS capability. Travelers who need data connectivity can use one of iRoamly’s data‑only plans, but for voice or text they will need to rely on internet‑based services. Popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection. However, some destinations may block or restrict certain apps, so it is advisable to verify that the messaging or calling apps you depend on work in Mauritius before purchasing a plan.
