JamboSim eSIM Data Plans for Serbia

JamboSim does not offer a true unlimited high‑speed data eSIM for Serbia. All of its plans that advertise “Unlimited” actually provide 3GB of high‑speed data per day; after that limit is reached the speed drops to 1000 kbps. For travelers who need more data without this throttling, JamboSim offers fixed‑data plans. For example, a 50GB plan valid for 30 days costs $75.99, and a 100GB plan for 180 days is available for $195.99. Choosing a fixed‑data package may be a more cost‑effective option unless you require continuous very high‑speed data usage.

JamboSim provides eSIM plans for Serbia that include a phone number and outbound SMS. The plans range from 1 GB for 7 days at $11.99 USD to 20 GB for 365 days at $105.99 USD, covering Serbia and 164 other countries. All phone numbers have the dialing code +1, meaning they are not local Serbian numbers but from the North American numbering plan.

Voice service on these plans is outbound only, and SMS service is also outbound only; inbound calls and SMS are not supported. For specific requirements, users should confirm details directly with JamboSim.

JamboSim’s catalog lists 12 single‑country and 50 multi‑country plans worldwide. The data set does not break down these totals by individual country, so a precise count of plans available specifically for Serbia is not available. Across its plans, JamboSim offers both fixed‑data and daily‑cap options: fixed plans provide a set amount of data for the validity period, while daily‑cap plans allow data usage up to a daily limit that rolls over each day. Prices range from about $1.99 to $196.99, and data caps cover 200 MB to 100 GB, with validity periods from 3 to 365 days.
