MobileSIM eSIM Data Plans for Serbia

MobileSIM does not provide an unlimited‑data eSIM for Serbia. The only plan that carries an “Unlimited” name is the Europe Unlimited data for 10 days, which actually offers 3 GB of high‑speed data per day. After that limit is reached, the speed is throttled to 1000kbps, so the plan is not truly unlimited.

Instead, MobileSIM offers a range of fixed‑data plans that give travelers a clear amount of high‑speed data. For instance, a 100 GB plan is available for 180 days at $185.00 USD, and a 50 GB plan for 90 days costs $100.00 USD. Other options include a 20 GB plan for 30 days at $27.00 USD, all of which provide full 4G or 5G speeds during the validity period. Choosing one of these fixed‑data plans is often more cost‑effective unless an exceptionally heavy data user requires more than the capped daily amount.

No, MobileSIM does not provide an eSIM for Serbia that includes a phone number or SMS capability. Only data‑only eSIM plans are available from MobileSIM for this country. Travelers can still communicate using VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, which allow calls and messaging without requiring a local phone number or SMS service.

MobileSIM provides a range of data plans in Serbia, including 6 single‑country and 17 multi‑country options that cover the country. Some of those plans use a fixed data amount, allowing a specific data cap for the validity period, while a single option offers a daily data cap, limiting the amount of data you can use each day. Across all plans the price varies from about $3 to $185, the data available spans 500 MB to 100 GB, and the validity window ranges from 3 days up to a full year.
