Superalink does not offer a Serbia eSIM plan that includes a local phone number or SMS services. Travelers who purchase a Superalink eSIM for Serbia will receive only a data‑only package; there is no provision for inbound or outbound voice calls or standard SMS through the network.
Because of this limitation, users typically rely on VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection. While these services usually work in Serbia, the availability of specific apps or VoIP services can change, so travelers are advised to confirm that the applications they need are accessible in Serbia before purchasing a plan.
