eSimfly eSIM Data Plans for Serbia

No, eSimfly does not have a truly unlimited data eSIM for Serbia. The plans that include “Unlimited” in the name provide a fixed high‑speed allowance of 3GB per day; after that amount the speed is throttled to 1000 kbps. If you need a larger continuous data allowance, eSimfly offers fixed data plans such as a 100 GB plan valid for 31 days or a 50 GB plan valid for 30 days, both of which give high‑speed data without a daily cap.

eSimfly does not provide an eSIM for Serbia that includes a local phone number or the ability to send or receive SMS. Their Serbian plans are only data‑only, so travelers can use the data connection for Internet access and for VoIP services such as WhatsApp, Telegram, or iMessage. However, some destinations may restrict or block certain VoIP apps, so it is advisable to confirm that the apps you rely on are accessible in Serbia before purchasing an eSimfly eSIM.

eSimfly offers a range of plans for travelers to Serbia that cover both single‑country and multi‑country options. In total there are 12 single‑country plans that apply exclusively to Serbia, and 53 multi‑country plans that include Serbia as part of a larger coverage area.

These plans vary in price from about $2.25 to $121.38 and in data allowance from 1 GB up to 100 GB. Validity periods span from 3 days to a full year (365 days). Within the collection, 18 of the plans set a daily data cap, meaning a fixed amount of data is available each day, while 47 provide a fixed data amount that is divided over the entire validity period. Tethering is allowed on applicable plans, and any reduced speed for certain uses is limited to 1000 kbps.
