JamboSim eSIM Data Plans for Serbia

JamboSim does not provide a true unlimited data plan for Serbia.
The plans marketed as “Unlimited” give 3 GB per day, and once that amount is reached the speed is throttled to 1, 000 kbps.

Travelers can choose larger fixed‑data plans instead. For example, a 100 GB plan valid for 180 days costs $185.99, a 50 GB plan for 30 days costs $71.99 or for 90 days $95.99, and a 20 GB plan for 30 days is available for $15.99 or $16.99. These fixed‑data options may be more cost‑effective for those who need more than 3 GB per day of high‑speed connectivity.

JamboSim does not provide a Serbian eSIM that includes a phone number and SMS capability. Travelers who need connectivity in Serbia can purchase a data‑only eSIM from JamboSim, and a voice number and text messaging are not offered. Voice calls and text messages can still be sent over the data connection using internet‑based applications such as WhatsApp, Telegram, or iMessage.

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.
