ZenSim eSIM Data Plans for Balkans countries

ZenSim does not provide a truly unlimited data eSIM for the Balkans. The plan titled “Balkans+ Unlimited STANDARD – 5 days” actually offers 15 GB of high‑speed data before any speed reduction applies, so it is not an unlimited plan.

If travelers need a larger data allowance, ZenSim offers several fixed‑data options. For example, a 40 GB plan is available for 30 days at $89, a 20 GB plan for 30 days at $48, and a 20 GB plan for 15 days at $45. These plans provide the same high‑speed data without an unlimited cap and can be more cost‑effective for most users.

ZenSim does not offer a Balkans eSIM plan that includes a phone number or SMS capability. The provider’s Balkans offerings are limited to data‑only eSIMs, which can be used for Internet access during the validity period of the plan.

Because the plans do not provide a traditional phone number or SMS service, travelers can instead rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage, which work over the data connection and allow voice calls and messaging without the need for a local phone number.

The ZenSim plan titled “Balkans+” provides coverage across Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia, and Kosovo.
