Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Serbia?
Firsty does not provide any unlimited data eSIM plans for Serbia. The available plans are fixed‑data packages, such as the Firsty First Class (Serbia) options that give 5GB of data per day for durations ranging from 1 day to 10 days. Because these plans have a set data allowance, they may be less cost effective for travelers who use a large amount of data; however, for moderate data consumers, the fixed data plans can offer a more predictable and often cheaper experience.
Does Firsty offer Serbia eSIM with phone number and SMS?
Firsty does not offer an eSIM for Serbia that provides a phone number or SMS capability. Only data‑only plans are available from the provider for this destination. Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection instead.
How many data plans does Firsty offer for Serbia?
Firsty offers 16 single‑country data plans for Serbia, with no multi‑country options available. The plans are divided into two categories: 14 daily‑cap plans that reset a daily data allowance, and 2 fixed‑cap plans that provide a one‑time data amount for the entire validity period. Prices range from about $3.35 to $179.48 and data caps vary from 1.5 GB to 5 GB. Validity spans 1 to 30 days, and some plans include a speed limit of 5 Mbps that drops to 512 Kbps once the data cap is reached.
