Gigapanda does not provide Estonia eSIMs that include a local phone number or the ability to send or receive SMS. All of the plans sold for Estonia by this provider are data‑only, with no telephony services attached.
Travelers can still use messaging and call apps such as WhatsApp, Telegram, or iMessage over the data connection, but because these rely on internet rather than SIM‑based SMS or voice, users should confirm that the apps are accessible in Estonia before purchasing, as some destinations may block or restrict certain VoIP services.
