esimzon eSIM Data Plans for Bulgaria

Esimzon does not provide a truly unlimited eSIM plan for Bulgaria.
All plans with “Unlimited” in the name actually allow 25GB of high‑speed data per day; after that amount the speed drops to 8000 kbps. For travelers who need unlimited usage, Esimzon offers fixed‑data alternatives such as the 300GB plans valid for 15 or 30 days, which give a large, non‑throttled data allowance. Such fixed plans are typically more cost‑effective for heavy data users who prefer a simple, capped amount rather than a “unlimited” plan that still has limits.

Esimzon does not provide eSIM plans for Bulgaria that include a local phone number or SMS capability. Their Bulgaria offerings are data‑only plans. Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection for voice and messaging needs.

esimzon offers 4 single‑country plans and 21 multi‑country plans for Bulgaria. The single‑country plans are primarily fixed data packages that provide a set amount of data for the entire validity period, while the multi‑country plans include both daily data cap packages—where the data allowance resets every day—and fixed data cap packages that last for the full validity period. In general, the price range of these plans spans from roughly $2.00 to $110.00, and the data caps vary from 1 GB up to 300 GB, giving travelers a broad spectrum of options depending on their usage needs.
