ETravelSim eSIM Data Plans for Serbia

ETravelSim does not offer a plan that provides truly unlimited high‑speed data for travel in Serbia. The plans that carry “Unlimited” in their name give a fixed daily allowance of 4GB, and after that limit a throttle of 128kbps is applied. Travelers who need a higher amount of high‑speed data can choose from fixed‑data options such as the 50GB 30‑day plan, which delivers 50GB of data at full speed for the period. These fixed‑data plans can be more cost‑effective for most users than purchasing a truly “unlimited’’ package.

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 six single‑country packages that cover Serbia. In addition a larger set of multi‑country packages—eighty‑three in total—include Serbia as one of the destinations. The prices of these plans range from roughly US $4.50 to US $109.99, the data caps span from 1 GB to 50 GB, and validity periods vary between 5 and 365 days. Some packages provide a fixed data amount that is available throughout the validity period, while others offer a daily data allowance that can be used each day of the plan.
