eSimfly eSIM Data Plans for Serbia

eSimfly does not provide a truly unlimited high‑speed data eSIM for travelers in Serbia. All plans labeled as “Unlimited” give a fixed 3GB per day allocation, after which the speed is throttled to 1000kbps. Travelers who need very large amounts of data can instead choose fixed‑data plans such as the Serbia Unlimited 30 days plan, which offers 3GB/day for 30 days at $34.40 USD, or the Global 100 GB 31 days plan, which supplies 100GB of high‑speed data for 31 days at $58.77 USD. These fixed‑data options may be more cost‑effective for heavy data users.

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 12 single‑country plans and 52 multi‑country plans that cover Serbia. Among these, 18 are daily data‑cap plans that replenish data each day, while 46 offer fixed data caps for the entire validity period. Prices range from roughly $2 to $107, and data allowances span from 1 GB to 100 GB over validity periods of 3 to 365 days.
