GIGAGO does not offer any Belarus eSIM plan that includes a phone number or SMS capability; only data‑only plans are available. Travelers who need to make calls or receive SMS messages would need to rely on internet‑based services.
For voice and messaging, apps like WhatsApp, Telegram, and iMessage can normally be used over the data connection. However, some destinations may restrict or block specific VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Belarus before purchasing an eSIM.
