Airalo does not currently sell an eSIM for Mauritania that includes a local phone number or the ability to send or receive SMS messages; the provider offers only data‑only plans for this destination.
Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though some destinations may restrict access to these services. It is advisable to check the availability of the apps you rely on in Mauritania before purchasing an eSIM.
