TailSim eSIM Data Plans for Serbia

TailSim does not provide a truly unlimited data eSIM for Serbia.
The plans that carry the word “Unlimited” in their name actually give 3 GB of high‑speed data each day for a fixed period and then throttle speed to 1000 kbps. Travelers can instead opt for one of TailSim’s fixed data plans, such as the 20 GB – 30 days bundle or the 10 GB – 30 days bundle, which offer larger data allowances without daily limits.

TailSim does not provide a phone number or SMS capability for Serbia; the provider only offers data‑only eSIM plans for that destination. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict access to these apps. It is advisable to confirm that the VoIP services you rely on are available in Serbia before purchasing a TailSim eSIM.

TailSim offers 13 single‑country plans for Serbia and no multi‑country plans. The plans fall into two categories: 8 daily data‑cap options, where a daily allowance can be set, and 5 fixed data‑cap options that provide a set amount of data for the entire validity period. Prices across all Serbian plans range from $3.99 to $82.50, while data caps vary from 1 GB to 20 GB, with validity periods spanning 3 to 30 days.
