ChillaxSIM eSIM Data Plans for Serbia

ChillaxSIM does not provide a truly unlimited data eSIM for Serbia. The plans marketed as “Unlimited Data” actually allocate 1GB of high‑speed data per day. After the daily allotment is reached the connection continues but at a reduced speed of 5000kbps. If you need a larger high‑speed data volume, ChillaxSIM offers fixed data plans, for example a 20GB plan for 30 days or a 50GB plan for 30 days, both of which provide 128kbps speed once the data cap is reached. Choosing a fixed‑data plan can be more cost‑effective for travelers who require more data than 1GB per day.

ChillaxSIM does not supply eSIM plans with a phone number or SMS capability for Serbia. Travelers who need voice or text services will need to use data‑only plans and rely on applications such as WhatsApp, Telegram, or iMessage over the data connection. While these VoIP applications generally work in Serbia, some destinations may limit or block access to certain services, so it is advisable to confirm the availability of the specific apps you rely on before purchasing a plan.

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).
