GigSky does not provide eSIM plans for Belarus that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from this provider. For voice and messaging, users must rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may place restrictions on these services, so it is advisable to confirm that the necessary apps are accessible in Belarus before buying an eSIM.
