Strong eSIM eSIM Data Plans for Balkans countries

Strong eSIM does not provide an unlimited data eSIM plan for the Balkans. Current offerings use fixed data allowances, such as the Balkan 20GB 30Days plan or the Balkan 10GB 30Days plan. These plans give a set amount of high‑speed data for the specified validity period. For travelers who use less than the total data allowance, a fixed plan may be a more economical option unless very heavy data usage is expected.

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.

Strong eSIM’s Balkan‑specific offering, named “Balkans (5+ areas)/Day, ” covers Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia, and Kosovo. The provider’s Global packages – “Global (120+ areas)/Day” and “Global139” – likewise include those Balkan states, adding both Bosnia and Herzegovina and Kosovo to the list of covered countries.
