ZenSim eSIM Data Plans for Bulgaria

ZenSim does not have a plan that offers unlimited high‑speed data for Bulgaria. The plans that include “Unlimited” in their name provide 3 GB per day; once that limit is reached the speed drops to 1 000 kbps.

If you need a larger, fixed data allowance, ZenSim offers alternatives such as the Bulgaria 40 GB plan valid for 30 days or the Bulgaria 20 GB plan valid for 15 days, both of which give a fixed amount of data without a daily quota.

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 that cover Bulgaria, and an additional 29 multi‑country plans that include Bulgaria in their coverage area. The available options span a price range from about $5 to $119 and data capacities between 1 GB and 40 GB, with some plans featuring a fixed data allotment and others a daily data cap. This provides travellers with a broad selection of data‑only packages suitable for short stays or longer visits.
