GulfData does not provide eSIM plans for Mauritania that include a phone number or SMS capability. Travelers who purchase GulfData eSIMs for Mauritania will only receive data access; the plans are purely data‑only. To make voice or text communications, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, access to these services may be limited in some destinations, so it is advisable to confirm that the preferred communication apps function normally in Mauritania before making a purchase.
