BlueSky eSIM eSIM Data Plans for Serbia

BlueSky eSIM does not provide a truly unlimited data plan for Serbia. The plans labeled “Unlimited Data” give 3GB per day; once that quota is reached the speed drops to a reduced 1000kbps.
Instead, BlueSky eSIM offers fixed‑data options. For example, a 20GB plan valid for 30 days costs $18.90 USD, while an equivalent A1 Serbia 20GB plan for 30 days costs $27.00 USD. These plans give a larger high‑speed data allowance without throttling and can be more cost‑effective for heavy data users.

BlueSky eSIM does not offer any plans for Serbia that include a phone number or SMS capability. Only data‑only eSIM plans are available from BlueSky eSIM for Serbia, and travelers can use VoIP applications such as WhatsApp, Telegram and iMessage over that data connection for calls and messaging.

BlueSky eSIM provides 11 distinct single‑country plans that cover Serbia. The plans vary in validity from 3 days to 365 days and offer data caps ranging from 200 MB up to 20 GB, with prices between roughly $1.97 and $69.92. The selection includes both fixed‑data‑cap options (where a set amount of data is allocated for the entire validity period) and daily‑cap plans (where a data allowance is reset each day). No dedicated multi‑country packages are available that include Serbia as a covered nation at this time.
