ETravelSim eSIM Data Plans for Serbia

ETravelSim does not offer a truly unlimited data eSIM for Serbia. Plans that carry the "Unlimited" name provide a fixed allowance of 4GB/day; after this daily limit is reached, high‑speed data is reduced to 128kbps according to the plan details.

The provider does offer fixed data plans that give larger fixed allowances. For example, the Travel eSIM for Europe 50 GB – 30 days / Data Only gives 50 GB for 30 days at a price of $29.19 USD and does not throttle speed after the data cap. Another option is the Serbia eSIM Unlimited – 30 days plan, which offers 4GB/day for 30 days and applies the reduced speed after the daily limit. Choosing a fixed data plan can provide higher speed and may be more cost‑effective for heavy data users.

ETravelSim does not offer any eSIM plans that provide a local phone number or SMS capability for travelers in Serbia. All of its Serbia packages are data‑only, allowing only internet access without the ability to receive voice calls or text messages to a local number. Travelers can still communicate over the internet using services such as WhatsApp, Telegram, or iMessage, which do not require a traditional phone number or SMS.

ETravelSim offers 6 single‑country plans that cover Serbia and 75 multi‑country plans that include Serbia as part of their network. These plans range in price from $4.50 to $109.99 and provide data caps between 1 GB and 50 GB. Among the offerings, 31 plans feature a daily data cap—allowing a set amount of data each day—while 50 plans use a fixed data amount for the entire validity period. This gives travelers a variety of options depending on how much data they need and whether they prefer a consistent daily allowance or a total data pool over the plan’s duration.
