nextSIM eSIM Data Plans for Bulgaria

nextSIM does not provide a truly unlimited data eSIM plan for Bulgaria. All listed plans give a fixed data allowance—either 1 GB/day or 2 GB/day—with speeds reduced to 512 kbps or 2000 kbps once the daily limit is exceeded. A few plans carry the word “Unlimited” in their name but still include these caps, so the data is not unlimited.

As alternatives, travelers can choose from higher‑cap fixed plans such as the eSIM Plus 10 Days Bulgaria (2 GB/day) or the eSIM Pro Bulgaria packages that offer 150 GB or 200 GB for 60–365 days. These options may be more cost‑effective for heavy data users compared to the capped “Unlimited” plans.

nextSIM does not offer an eSIM for Bulgaria that includes a phone number or SMS capability. The provider sells only data‑only plans for Bulgaria; there are no options that provide inbound or outbound calls or SMS. Travelers who need messaging or calling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which work without a local phone number or SMS ability.

NextSIM lists 75 single‑country plans that cover only Bulgaria, and 61 multi‑country plans that include Bulgaria as part of a broader European coverage package. Prices for these plans range from roughly $1.38 to $1, 272.63, while the data allowances span from 1 GB to 200 GB and validity periods from 1 day to 365 days. Some of the packages are fixed‑data plans, giving a set amount of data for the whole validity period, whereas others are daily‑data‑cap plans that limit the amount of data you can use each day.
