MobiMatter does not offer a Global (World) eSIM that includes a phone number or SMS capability. Travelers who purchase a Global plan from MobiMatter receive only a data‑only connection, with no ability to receive or make standard voice calls or send SMS messages through the network. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, availability of these services may vary by country, so travelers should verify that the apps they need to use are accessible in the destinations they plan to visit before purchasing.
