Stellar eSim does not provide eSIM plans for Mauritania that include a phone number or SMS capability. Only data‑only eSIMs are available. If you need to communicate, consider using VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but keep in mind that some destinations may block or restrict access to these services, so verify that the apps you intend to use work in Mauritania before purchasing.
