Sim Local does not provide an unlimited‑data eSIM plan for Serbia. The available plans are fixed‑data bundles, each with a hard cap and a set validity period. For example, the Orange Holiday World 100 GB plan offers 100 GB of data for 31 days at $90.50 USD, and the Orange Holiday World 50 GB plan provides 50 GB for 31 days at $67.75 USD. Other options include the Serbia 20 GB for 30 days plan at $33.00 USD and the Serbia 10 GB for 30 days plan at $18.50 USD, all of which are limited‑data bundles with specified validity dates.
Choosing a fixed‑data plan can be more cost‑effective for most travelers, especially those who do not need extremely high data usage. Only a very heavy data consumer might consider a different pricing model, but for most users the fixed‑data options above offer a straightforward and predictable way to keep online access while in Serbia.
