Ubigi does not provide an eSIM plan for Monaco that includes a local phone number or SMS capability. Travelers can only purchase data‑only eSIMs from Ubigi for use in Monaco. To make and receive voice or text messages, users will need to rely on internet‑based VoIP applications such as WhatsApp, Telegram or iMessage. However, some destinations may block or restrict access to these apps, so it is advisable for travelers to confirm that the services they rely on are available in Monaco before buying a data‑only plan.
