ZenSim eSIM Data Plans for Bulgaria

No. ZenSim does not provide a high‑speed data plan that truly offers unlimited data in Bulgaria. The plans that carry “Unlimited” in their name deliver a fixed daily allowance of 3GB, after which the speed is reduced. In Bulgaria, the fixed‑data options include the Bulgaria 40GB – 30 days plan for $45.00 USD and the Bulgaria 20GB – 30 days plan for $24.00 USD, among others. These fixed data plans can be more cost effective for most travelers, whereas a truly unlimited high‑speed plan is not currently available.

ZenSim does not offer eSIM plans for Bulgaria that include a phone number or SMS functionality; only data‑only options are available from this provider.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Bulgaria before purchasing, as some destinations may block or restrict certain apps.

ZenSim offers 11 single‑country plans and 24 multi‑country plans that include Bulgaria. Available plans come in two main varieties: fixed‑data packages that provide a set amount of data (ranging from 1 GB to 40 GB) and daily‑cap options that allow a specified amount of data per day. Overall, prices run from roughly $5 for the smallest 1 GB package up to about $89 for the largest 40 GB bundle.
