ChillaxSIM eSIM Data Plans for Serbia

ChillaxSIM does not provide a true unlimited data plan for Serbia. The plans labeled “Unlimited” give 1GB of high‑speed data per day and after that limit the speed to 5000kbps. For travelers who need more data, ChillaxSIM offers fixed‑data options such as a 20GB plan valid for 30 days costing $22.32 USD or a 10GB plan for 15 days priced at $11.56 USD. These larger data allowances are available at a lower daily cost and may be more cost‑effective for heavy data users.

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).
