Firsty eSIM Data Plans for Balkans countries

Firsty offers an unlimited data eSIM plan for the Balkans named Firsty Free. The plan has a validity of 1 day, is priced at $0.00 USD and includes advertising. The maximum speed supplied by the network is 256 kbps, and the data is subject to a Fair Usage Policy, meaning that after heavy usage speeds may be throttled.

Because the plan is limited to 1 day and carries a Fair Usage restriction, users who need to know how long normal speeds typically last or whether additional data can be accessed after throttling should contact Firsty directly for clarification. The plan covers Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia, plus 103 other countries.

Firsty does not provide a Balkans eSIM with a phone number or SMS capability. The available plans are data‑only, so travelers cannot receive or send standard SMS messages through a local number. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which function over the data connection without requiring a local phone number.

The Firsty Free plan covers the following Balkan countries: Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, and Serbia.
