RedSim eSIM Data Plans for Serbia

RedSim does not have a plan that provides truly unlimited high‑speed data for Serbia. The plans titled “Serbia Unlimited” or “Europe (41 countries) Unlimited” provide up to 3 GB per day or 5 GB per day, respectively; after those daily limits the speed is throttled to 1 Mbps. For travelers who need more data without daily caps, RedSim offers fixed data plans such as a 20 GB 30‑day plan and a 50 GB 30‑day plan, both available for Serbia. These fixed plans give a set amount of high‑speed data that is used over a 30‑day validity period and can be more cost‑effective for moderate to heavy data usage.

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.

RedSim offers 21 single country plans that cover Serbia and 17 multi country plans that include Serbia. The available plans range in price from $1.69 to $75.60 and in data from 1 GB to 50 GB. Some plans provide a fixed data amount, while others offer a daily data cap, giving customers flexibility depending on their usage patterns.
