eSIM2Me does not provide an unlimited data eSIM for Serbia. All of the plans listed for Serbia have a specific data cap, such as 100GB or 50GB, and a defined validity period.
Travelers who need a large amount of data can choose from the available fixed data plans. For example, the Global Orange 100GB plan offers 100GB of data for 30 days, while the Europe & Balkans 50GB plan provides 50GB for 3, 5, 7, or 10 days. These fixed data plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from a truly unlimited option.
