ChillaxSIM eSIM Data Plans for Serbia

ChillaxSIM does not provide a truly unlimited data eSIM for Serbia. All plans labeled “Unlimited” in the catalog offer a capped rate of 1GB per day, after which the data speed is reduced to 5000kbps.

Instead, ChillaxSIM offers fixed‑data options that are often more cost‑effective for heavier usage. For example, a 20GB plan is available for 30 days at $18.90 USD, and a 10GB plan for 15 days is priced at $10.90 USD. A larger 50GB plan for 30 days is also offered at $81.90 USD, though it comes with a reduced speed of 128kbps once the allowance is exceeded. These alternatives give travelers a clear amount of high‑speed data before any throttling applies.

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).
