eSIMzio eSIM Data Plans for Serbia

eSIMzio does not provide a true unlimited data eSIM for Serbia. Every plan listed for Serbia has a hard limit of 3GB per day. Once a traveler uses 3GB on a day the speed drops to 1 Mbps, as recorded in the plan features.

For travelers needing a larger allowance, eSIMzio offers fixed data plans. For example, the Serbia Unlimited plan for 30 days gives 3GB per day, or the Europe 100 GB plan for 180 days offers 100GB of high‑speed data. These plans provide a fixed amount of high‑speed data for the specified validity period and can be more cost‑effective than choosing a truly unlimited option.

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.
