eSimfly eSIM Data Plans for Serbia

eSimfly does not provide a true unlimited data eSIM for Serbia. Every plan that carries the word “Unlimited” actually includes a fixed high‑speed data allowance, such as 1 GB per day or 3 GB per day, after which the speed is throttled. Travelers who need more data can choose one of the fixed plans, for example a 50 GB high‑speed package valid for 30 days, priced at $31.64 USD for coverage across Serbia and 41 other European countries, or the Serbia‑only 50 GB 30‑day plan at $76.94 USD. These examples illustrate the available options for large data allowances, though other fixed‑data plans are also available.

eSimfly does not provide a Serbia eSIM plan that includes a phone number or SMS capability. The only eSIM options from this provider for Serbia are data‑only plans, which allow internet access via 5G, 4G, or 3G, but do not support traditional voice calls or SMS. Travelers who need messaging or calling can instead use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

eSimfly provides 15 single‑country plans for Serbia and 40 multi‑country plans that include Serbia. The single‑country plans allow usage solely within Serbian borders, while the multi‑country plans offer additional roaming to other countries listed in the package. Across both categories the price range spans from about $1.67 to $193.75, the data cap ranges from 1 GB up to 50 GB, and validity periods vary from 1 day to 365 days. Some plans feature a daily data cap, whereas others offer a fixed data amount for the entire validity.
