JamboSim eSIM Data Plans for Serbia

JamboSim does not provide a truly unlimited high‑speed data plan for Serbia. Their “Unlimited” packages give 3GB of high‑speed data per day, and once that limit is reached the speed drops to 1000kbps. The name “Unlimited” therefore refers to a daily cap rather than an open‑ended, unrestricted data allowance.

If a traveler requires more data without the daily cap, JamboSim offers fixed‑data options such as a 100GB plan valid for 180 days and a 50GB plan valid for 30 days (and longer). These plans provide a larger total amount of high‑speed data and may be more cost‑effective for heavy data users.

Yes, JamboSim sells eSIM plans for Serbia that include a phone number and the ability to send SMS. The numbers are US‑based, with a dialing code of +1, and they support outbound voice calls and outbound text messages. Prices start at US $11.99 for a 1 GB plan valid for 7 days and go up to US $101.99 for a 20 GB plan valid for 365 days. Each plan allows data usage of 1 GB to 20 GB, with validity ranging from one week to one year. For precise call and SMS capabilities or if local Serbian numbers are required, users should verify details directly with JamboSim.

JamboSim provides 12 single‑country plans and 34 multi‑country plans for Serbia. Among these, 12 plans feature a daily data cap, giving travelers a set amount of data each day, while 34 plans use a fixed data cap, allowing the full data allowance at any time during the validity period. Prices for all Serbia plans range from about $1.99 to $185.99, and data caps vary from 200 MB up to 100 GB, giving a broad selection for different usage needs.
