Strong eSIM eSIM Data Plans for Balkans countries

Strong eSIM does not have an unlimited data eSIM for the Balkans. The provider’s Balkan coverage is limited to fixed‑data plans, such as the 20GB plan valid for 30 days priced at $74.90 USD and the 10GB plan also valid for 30 days priced at $39.90 USD. These fixed plans may be more cost‑effective for most travelers unless they anticipate extremely high data usage that would justify an unlimited plan, which Strong eSIM does not currently offer for this region.

Strong eSIM does not provide Balkans eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are offered for the Balkans. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging without requiring a phone number or SMS.

The Strong eSIM “Balkans (5+ areas)/Day” plan covers Albania, Bulgaria, Croatia, Montenegro, North Macedonia, and Serbia, while the “Global (120+ areas)” plan—and its variant Global139—include the entire Balkans region by covering Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Montenegro, North Macedonia, and Serbia. All of the above countries appear across at least one of these plans, ensuring full coverage of the Balkans for travelers using Strong eSIM.
