Giga.Tel does not provide eSIM plans with a phone number or SMS messaging for Moldova; all available plans are data‑only. While this limits direct voice and text capabilities, travelers can typically use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to confirm that the applications you rely on are accessible in Moldova before purchasing.
