4S eSIM eSIM Data Plans for Balkans countries

4S eSIM does not provide a truly unlimited data plan for the Balkans. All plans that carry “Unlimited” in the name, such as Balkans+ 3GB Unlimited or Balkans+ 30GB Unlimited, have a set data cap and a reduced speed of 1000 kbps once the cap is reached. For travelers who need more data, 4S eSIM offers fixed‑data alternatives, for example a 50GB plan valid for 90 days or a 30GB plan valid for 30 days, both of which give the user a large high‑speed allowance before any throttling occurs. Choosing a fixed data plan can be more cost‑effective for most users compared to the capped “Unlimited” options.

4S eSIM does not offer an eSIM plan with a phone number or SMS capability for the Balkans. Only data‑only plans are available for this region.

Travelers who need to make calls or send messages can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations in the Balkans may block or restrict access to certain apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible before purchasing.

The 4S eSIM Balkans+ plan covers Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, and Serbia. The Global plan includes the same Balkan countries plus coverage in many other regions worldwide.
