ChillaxSIM eSIM Data Plans for Serbia

ChillaxSIM does not provide a truly unlimited data eSIM for Serbia. The plans that carry “Unlimited” in their name actually supply 1 GB per day of high‑speed data; once that limit is reached the connection is throttled to 5120kbps. Therefore, the data is not unlimited and the speed is reduced after the 1 GB threshold is reached.

Travelers who need more data can choose one of ChillaxSIM’s fixed data plans. For example, the “Serbia Total 20GB for 30 days” plan gives 20 GB of high‑speed data for 30 days at $18.90 USD, while the “Serbia Total 10GB for 15 days” plan provides 10 GB for 15 days at $10.90 USD. These options give larger data allowances at a flat rate and may be more cost‑effective for heavy‑usage travelers.

ChillaxSIM does not provide any eSIM plans that include a phone number or the ability to send or receive SMS messages for travelers heading to Serbia. The available plans are strictly data‑only and do not support traditional voice or text services. To communicate while in Serbia, users can rely on internet‑based applications such as WhatsApp, Telegram, and iMessage, which work over the data connection and allow calls and messaging without a local phone number or SMS capability.

ChillaxSIM currently offers 29 single coverage plans specifically for Serbia, providing a fixed data allowance ranging from 1GB to 50GB. Additionally, they have 42 plans that offer coverage across multiple countries, including Serbia, which generally feature a daily data cap. These plans also include options with features like tethering allowed and reduced speeds at certain data thresholds (128kbps or 5120kbps).
