eSimpli eSIM Data Plans for Serbia

eSimpli does not provide a truly unlimited data eSIM for Serbia.
Its “Unlimited” plans are capped at 1 GB per day and, once that amount is used, the connection speed drops to 1250 kbps.
If a traveler wants a higher data allowance, eSimpli offers fixed‑data options such as the eSIM Balkans 50GB for 30 days (priced at $80.06 USD) and the eSIM Balkans 20GB for 30 days (priced at $42.29 USD). These fixed plans are often more cost‑effective unless a user requires a very large data volume.

eSimpli does not provide any eSIM plans with a phone number or SMS capability for travelers in Serbia. The only plans offered are data‑only eSIMs.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Because some destinations may block or restrict access to specific apps, it is advisable to check that the applications you rely on are available in Serbia before buying a plan.

eSimpli has six single‑country plans that cover only Serbia, and it also offers eleven multi‑country plans that include Serbia. The plans range from about $9.10 up to $108.68 and provide between 1 GB and 50 GB of data, with validity periods between 5 and 30 days. Some plans are based on a fixed data allowance, while others use a daily data cap and may allow tethering with reduced speed after the cap is reached.
