Stellar eSim does not provide a Mayotte eSIM that includes a phone number or SMS. Travelers must rely on data‑only plans from this provider. Voice and messaging can still be achieved over the data connection with popular VoIP applications such as WhatsApp, Telegram, and iMessage, but some destinations may restrict access to particular apps or services, so travelers should verify that the apps they need are usable in Mayotte before purchasing a plan.
