Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Bulgaria?
Firsty offers an unlimited data eSIM plan specifically for Bulgaria: the Firsty Free plan. It provides unlimited high‑speed data for 1 day at no cost, but a note on the plan indicates that while data is unlimited, the connection may be throttled and is capped at a maximum speed of 256 kbps. The plan also contains advertising.
If you need data beyond the 1‑day period or prefer a higher speed without throttling, Firsty’s other Bulgarian plans deliver 5 GB per day for up to 10 days, but they have a capped allowance. Because the free plan’s speeds may be reduced after heavy use, it is advisable to contact Firsty directly to confirm the fair‑usage policy and typical speeds you can expect at normal use.
Does Firsty offer Bulgaria eSIM with phone number and SMS?
Firsty does not provide eSIM plans for Bulgaria that include a local phone number or SMS functionality. Only data‑only eSIMs are available from this provider for the country. Travelers who need to stay connected can use internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage over the data connection.
How many data plans does Firsty offer for Bulgaria?
In the Bulgaria market, Firsty lists 16 single‑country plans and one multi‑country plan. Their catalog includes both daily data‑cap options and fixed data‑cap packages; daily plans allow a set amount of data per day, while fixed plans provide a total data allowance for the full validity period. Prices spread from free to about $70 and data caps range from 1.5 GB to unlimited, with validity periods from one to thirty days.
