MobileSIM eSIM Data Plans for Serbia

MobileSIM does not provide a truly unlimited data eSIM for Serbia. All plans with “Unlimited” in the name actually give 3 GB of high‑speed data per day; after that daily limit the speed drops to 1000 kbps. For travelers who need more data, MobileSIM offers fixed‑data options such as the 50 GB plan for 30 days or the 20 GB plan for 30 days. These fixed‑data plans allow uninterrupted high‑speed data until the chosen allowance is met, and they can be more cost‑effective unless the user requires very heavy data usage.

MobileSIM does not provide an eSIM that includes a Serbian phone number or SMS capability for travelers. Only data‑only plans are offered for Serbia.

Even though a local phone number is not available, the data connection can be used with VoIP applications such as WhatsApp, Telegram, iMessage and other internet‑based messaging or calling services.

MobileSIM provides 19 multi‑country data plans that cover Serbia; the provider does not offer any single‑country plans exclusively for Serbia.
The plans are divided into two categories. Fixed data cap plans range from 500 MB to 50 GB and come with a set amount of data that does not change during the validity period. Daily data cap plans offer a data allowance that resets each day, usually designed for short‑term travelers needing a predictable daily usage quota.
Prices for the Serbian‑inclusive plans vary from about $1 to $99, with validity periods that can be as short as 3 days or as long as 30 days. The data caps offered across the entire range span from the 500 MB minimum up to 50 GB, giving travelers a broad selection based on budget and data needs.
