Giga.Tel does not provide an eSIM for Monaco that includes a phone number or SMS capability; the only plans offered by the provider for that destination are data‑only. Travelers who need voice or messaging services must rely on internet‑based options.
VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for calls and messaging, although some destinations may limit or block specific apps. Users should confirm that the messaging or calling apps they depend on are accessible in Monaco before choosing a data‑only plan from Giga.Tel.
