Ovosim does not provide a true unlimited data eSIM for Bulgaria. The plans that carry “Unlimited” in their name are limited to a specific daily or total data allowance—for example, EUconnect Unlimited 3 Days offers 10GB per day over 3 days, and EU 120 GB Unlimited Calls supplies 4GB per day for 30 days. Therefore, a plan with unlimited high‑speed data without a maximum is not available.
Travelers can instead choose from fixed data plans that give substantial allowances. For instance, Bulgaria 100 GB 6 Months supplies 102 GB over 180 days, and Half Global 120 GB Yearly provides 123 GB for 365 days, both including coverage in Bulgaria. These alternatives can be more cost‑effective unless the user expects extremely heavy data usage.
