JamboSim eSIM Data Plans for Serbia

JamboSim does not provide a true unlimited data eSIM for Serbia. The plans that carry the word “Unlimited” in their name actually offer a fixed 3GB per day of high‑speed data and after that limit is reached the speed is reduced to 1000kbps. For travelers who need more data, JamboSim sells larger fixed‑amount plans, such as the 50GB plan valid for 30 days or the 100GB plan valid for 180 days. Choosing one of these larger data plans is usually more cost‑effective unless a user requires a high‑speed data allowance for a very short period.

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 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.
