eSIMCard eSIM Data Plans for Serbia

eSIMCard does not provide a truly unlimited high‑speed data eSIM for Serbia. The plans that carry “Unlimited” in their name actually offer 1GB or 2GB of high‑speed data per day (or 1GB total for a 1‑day token) and then throttle the speed to 512 kbps or 2000 kbps after the limit is reached. Because the data allowance is capped, the service is not unlimited in the strict sense.

For travelers who need a larger, fixed amount of data without throttling, eSIMCard offers 100GB plans. A 100GB eSIM for 30 days in the Europe Max network, which includes Serbia, costs $82.21 USD and provides continuous 5G coverage. A longer‑term option is a 100GB eSIM for 180 days in the same network for $99.59 USD. These fixed‑data plans give a single, large allowance and avoid the speed reduction that applies to the “Unlimited” plans.

eSIMCard does not offer a Serbia eSIM plan that includes a phone number or SMS capability; the provider offers only data‑only eSIMs for the country.

Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, which function without a local phone number.

eSIMCard lists 31 single‑country data plans for Serbia and does not offer any multi‑country plans for that country. The available plans cover a price range from about $2.43 to $526.40 and provide between 1 GB and 100 GB of data during validity periods of 1 to 180 days. Among the plans, some provide a fixed data amount for the entire validity, while others apply a daily data cap that resets each day, allowing users to choose the type that best suits their usage patterns.
