RedSim eSIM Data Plans for Serbia

RedSim does not provide a truly unlimited data eSIM for Serbia. The plans that carry “Unlimited” in their name give high‑speed data up to 3GB per day (or 5GB per day for the Europe‑wide options) and then throttle the speed to 1000kbps for the remainder of the day.

Travelers who need more data can choose from RedSim’s fixed data plans, such as the 20GB 30‑day plan for Serbia or the 50GB 30‑day plan that covers Serbia and 40 other European countries. These plans offer a set amount of high‑speed data that must be used within the validity period, and they can be more cost‑effective for users who consume large amounts of data.

RedSim does not provide eSIM plans for Serbia that include a phone number, voice calling or SMS. Travelers looking to do phone calls or send text messages in Serbia will need to rely on data‑only connections and use VoIP applications such as WhatsApp, Telegram or iMessage. While these services often work over a data connection, certain destinations can restrict access to specific VoIP apps, so it is advisable to confirm that the applications you rely on are available in Serbia before purchasing a plan.

The dataset lists 31 single‑country and 17 multi‑country data plans for RedSim overall, but it does not provide a country‑specific breakdown. Consequently, the exact number of RedSim plans that are available for Serbia is not specified in the available data.
