eSIMNEXA does not provide Serbia eSIM plans that include a phone number or SMS capability. The provider only offers data‑only eSIMs for Serbia, so travelers will not receive an international dialing code or the ability to send or receive traditional text messages.
If voice or text communication is needed while traveling in Serbia, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations restrict access to specific apps or VoIP services, so travelers should confirm that the apps they depend on are accessible in Serbia before purchasing an eSIMNEXA data plan.
