ZenSim eSIM Data Plans for Balkans countries

ZenSim does not offer a truly unlimited data eSIM for the Balkans. The only plan it marks as “Unlimited” provides 3GB of high‑speed data per day, and once that daily allocation is reached the speed is throttled to 1000 kbps, making it a fixed‑data plan with a reduced‑speed cap.

For travelers who need more consistent high‑speed data, ZenSim lists several fixed plans. For example, the Balkans+ 40 GB plan lasts for 30 days and costs $89.00 USD, while the Balkans+ 20 GB plan is available for 15 or 30 days at $45.00–$48.00 USD. These fixed‑data options avoid the post‑cap speed reduction and provide a more predictable experience for most users.

ZenSim does not provide eSIM plans for the Balkans that include a phone number or SMS capability. Available options are data‑only eSIMs that allow internet access. Travelers who need voice or text communication can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in the specific Balkans country they plan to visit, as some destinations may block or restrict certain VoIP services.

ZenSim offers two plans that include the Balkan countries. The Balkans+ plan covers Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia, and Kosovo. The Global plan also includes the same set of Balkan countries in its coverage.
