MobiMatter does not currently provide a Mauritania eSIM that includes a local phone number or SMS capability. Only data‑only plans are sold for use in Mauritania.
Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to particular apps, so it is advisable to verify that the services you rely on are accessible in Mauritania before purchasing an eSIM.
