Flysimo does not provide any unlimited data eSIM plan for Serbia. Travelers who need data in Serbia can instead choose from Flysimo’s fixed data plans, such as the Serbia 20GB 30Days plan or the Europe 50GB 180Days plan that includes coverage for Serbia. These fixed‑data options may offer a more cost‑effective solution for most users, unless a traveler requires very high data consumption.
Flysimo does not provide an eSIM plan for Serbia that includes a phone number or SMS capabilities. Only data‑only eSIM options are available through the provider.
Travelers who need to make or receive calls and messages can use VoIP services such as WhatsApp, Telegram, or iMessage, which work over the data connection and do not require a local phone number or SMS service.
Flysimo provides a mix of single‑country and multi‑country eSIM offerings that cover Serbia, with 7 distinct single‑country plans and 32 multi‑country plans that include Serbia in their coverage portfolio. The available plans span a price range from about $3.19 to $153.30, while the data caps offered vary from 1 GB up to 50 GB, allowing travelers to choose between modest data packages for short stays or larger bundles suitable for longer trips or heavier usage.
