Esimify does not offer any Serbian eSIM plans that include a phone number or SMS capability. The provider sells only data‑only eSIMs for Serbia, so travelers cannot receive or make conventional voice calls or text messages on the local network.
Users who rely on voice or text can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict access to these services, so it is advisable to verify that the apps you need are fully usable in Serbia before purchasing a plan.
