Kolet eSIM Data Plans for Bulgaria

Kolet does not provide a truly unlimited data eSIM for Bulgaria. Its plans that carry the word “Unlimited” in the name actually supply 5 GB of high‑speed data each day; once that daily allowance is used the connection is throttled to 1024 kbps. The data cap remains the same whether the plan is sold for one, three, five, or thirty days, and the plan is considered fixed because the allowance must be used within the specified validity.

For travelers who need more data or prefer a straightforward data budget, Kolet offers fixed data plans such as the 20 GB for 30 days plan, which costs $20.49 and delivers the full 20 GB of high‑speed data with no speed reduction until the data is consumed. These fixed plans can be more cost‑effective for moderate or higher usage throughout a stay in Bulgaria.

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.
