eSIMzio eSIM Data Plans for Serbia

eSIMzio does not provide a true unlimited data eSIM for Serbia. All plans that carry “Unlimited” in the name are actually fixed‑data plans with a hard cap: the Serbia Unlimited options give 3GB of high‑speed data per day, while the Europe Unlimited options offer 5GB per day. After the daily quota is used, speeds are reduced to 1 Mbps.

If a traveler needs a large amount of data without a daily limit, eSIMzio offers several fixed‑data alternatives. For example, the Serbia Unlimited 30‑day plan supplies 3GB of high‑speed data per day for 30 days, and the Europe 100 GB plan provides 100GB of data for 180 days. These plans can be more cost effective than pretending an unlimited plan is available.

eSIMzio does not provide a Serbia eSIM that includes a local phone number or SMS capability. The provider only offers data‑only plans for Serbia. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Serbia before purchasing, as some destinations may block or restrict certain apps.

eSIMzio offers 12 single‑country plans and 41 multi‑country plans for Serbia. The plans span a price range from about $2.03 to $228.12 and data caps from 200 MB up to 100 GB, with validity periods between 3 and 365 days. The single‑country options are primarily fixed‑data plans, while the multi‑country selections include both fixed‑data and daily‑data‑cap plans, allowing travelers to choose between a set amount of data for the entire validity or a daily allowance that resets each day.
