Kolet eSIM Data Plans for Bulgaria

Kolet does not offer a true unlimited data eSIM for Bulgaria. The plans that carry the “UNLIMITED” name apply a hard limit of 5GB per day; after that daily quota the speed drops to 1024 kbps. Travelers can instead choose fixed data plans such as the Bulgaria 20GB for 30 days plan, the Bulgaria 10GB for 30 days plan, or a 5GB‑day plan that can run from 1 to 30 days in validity, each with the same 5GB/day allowance before a speed reduction. Fixed plans often provide a clearer cost‑benefit balance unless an extremely heavy data consumer is required.

Kolet does not offer eSIM plans for Bulgaria that include a phone number or SMS capability. All of Kolet’s Bulgaria eSIM options are data‑only.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but not every destination allows full access to these services. It is advisable to confirm that the apps you rely on can be used in Bulgaria before purchasing a plan.

Kolet offers a total of 13 single‑country plans and 31 multi‑country plans that cover Bulgaria.
Of the available options, 21 plans are structured around a daily data cap while 23 use a fixed data cap. The plans range in price from about $3.99 to $104.40 and provide data allowances between 1 GB and 20 GB.
