MobiMatter does not offer a Romania eSIM that includes a phone number or SMS capability. Travelers can only purchase a data‑only eSIM from the provider. Outlook on voice and messaging can still be achieved through popular VoIP apps such as WhatsApp, Telegram, and iMessage, using the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should verify that the apps they rely on are accessible in Romania before purchasing.
