eSIMatrix does not provide an unlimited data eSIM for the Balkans region. The available plans are fixed‑data bundles that deliver a set amount of high‑speed data for 30 days, the largest of which is 20 GB for $80.00 USD.
Choosing a fixed‑data plan can be more economical for most travelers, unless you anticipate consuming data at a very high rate. Other options include the 10 GB bundle for $43.50 USD and the 5 GB bundle for $23.00 USD, all of which cover Albania, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia, and one additional country.
