Manet Travel does not offer eSIM plans that provide a phone number or SMS capability for Serbia. Travelers can only purchase data‑only plans, which include high‑speed internet access through 4G or 5G networks. For voice and text communication, popular VoIP apps such as WhatsApp, Telegram, and iMessage can usually be used over the data connection. However, some destinations may restrict access to specific apps or VoIP services, so users should verify that their preferred applications are available in Serbia before buying a plan.
