thirr.com does not currently provide any unlimited data eSIM plans for the Balkans. Travelers who need unrestricted data must look to other providers.
Instead, thirr.com sells fixed‑data eSIMs that cover the Balkans with large allowances. For example, the EU BASE 100GB 30D plan gives 100GB of high‑speed 5G data for 30 days and is priced at $35.43 USD, while the EU BASE 50GB 365D plan offers 50GB of data for 365 days at $59.06 USD. Both plans cover Albania, Bulgaria, Croatia, Montenegro, Serbia, and an additional 43 European countries. Choosing a fixed‑data plan can be more cost‑effective for most users, unless one requires very heavy data usage beyond the available caps.
thirr.com does not offer a Balkans eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available for the Balkans, so travelers will need to rely on VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging.
EU BASE 3D covers Albania, Bulgaria, Croatia, Montenegro and Serbia, while EU PLUS 15D extends that list by adding Bosnia and Herzegovina and North Macedonia. Both HALFWORLD 3D and ALLWORLD 7D include the full set of eight Balkan states—Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia and Kosovo. The XXL World 31D family of plans—XXL World, XXL World 2, XXL World 3, XXL World 4 and XXL World 5—all provide coverage for Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia and Serbia.
