Kolet eSIM Data Plans for Bulgaria

Kolet does not provide a truly unlimited data eSIM for Bulgaria. The plans that carry the “UNLIMITED” name give 5GB per day at full speed and then throttle the connection to 1024 kbps once that daily limit is reached, so they are fixed‑data plans rather than unlimited ones.

Travelers who need a larger data allowance can choose from Kolet’s fixed‑data plans, such as the Bulgaria 20GB for 30 days plan priced at $20.49 or the Bulgaria 10GB for 30 days plan priced at $13.49. These plans offer a set amount of high‑speed data that must be used within the specified validity period.

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.
