Bulgaria Route Matrix: eSIM Columns Leg by Leg (2026)

Heading to Bulgaria for a long weekend? Light data use (maps and messaging) runs about 1.5GB over 3 days on A1 Bulgaria's 4G LTE network, which the 3GB at $3.47 covers. A moderate user using social media and navigation needs 4 to 5GB, so go with the 5GB at $5.20. Heavy users streaming or video-calling need 10GB or more; buy the largest fixed plan available. For a typical weekend traveler, the 5GB at $5.20 fits most weekend travelers without overpaying for unused data.

Longer trips to Bulgaria cost less per day because bigger plans spread the price across more days. 7 days: 20GB plan at $17.03 total ($2.43/day). 14 days: 50GB plan at $38.43 total ($2.75/day). 30 days: unlimited at $1.78/day (32% off base rate), with full speed for the first 2 GB each day. Moving from 7 to 14 days cuts the daily rate by -13%. The 14-day bracket balances daily rate and flexibility for most travelers visiting Bulgaria.

You can top up your Bulgaria eSIM through any of the five provider apps while traveling. Airalo lets you buy additional data through the app in real time, and the top-up lands on the eSIM profile already installed. Unlimited plans are also sold by the day: the 1-day Bulgaria plan in the plan table costs $2.62, with full speed for the first 2 GB each day. Saily and Nomad both support fixed-data top-ups with no reinstallation. A top-up of 1GB costs $2.21, the same as buying a new plan. Buying a larger plan upfront is cheaper per GB than topping up, but the option is always available if you underestimate your usage.

Yes, eSIMs work in Bulgaria. The network section on this page lists the local operators for Bulgaria; the list does not say which one a phone joins. Google Pixel 3 and later, iPhone XR and later, and Samsung Galaxy S21 and later all work. Download your eSIM profile before departure so you connect the moment your plane touches down in Bulgaria.

No, unused data does not roll over. Once your Bulgaria eSIM plan expires, any remaining gigabytes are lost. Buy a plan that matches your actual trip length, not a larger buffer. The 20 GB Bulgaria plan at $17.03 lasts 30 days from activation; data left when it ends does not carry over. If you change plans before installing, HelloRoam refunds an unactivated eSIM for 180 days, the same window Holafly gives unused plans, against 14 days at Airalo.

Single-country eSIM plans for Bulgaria do not extend to other European destinations. For multi-country European trips, HelloRoam sells one Europe plan covering 33 areas, with 7 days of unlimited data at 3GB a day at full speed for $23.53 (catalogue checked 29 Oct 2026). Airalo's Eurolink bundle cost $31 for 10GB over 30 days (read 30 Oct 2026). Each plan covers its own country list. If Bulgaria is your only stop, a single-country plan is cheaper: 20GB at $17.03 for a 7-day trip. EU roaming rules do not apply to travel eSIMs because each plan is a standalone purchase.

No, a single-country Bulgaria eSIM deactivates outside Bulgaria's borders. Plan your data use for the exact days you are in Bulgaria. For trips combining Bulgaria with other European stops, a regional bundle covers the full itinerary on one purchase. A 50GB plan at $38.43 fits a two-week Bulgaria stay, but it stops working the moment you cross the border.

Your daily data cost in Bulgaria shrinks when you commit to a longer plan. A 7-day stay fits the 20GB plan at $17.03 ($2.43/day). A 14-day stay fits the 50GB plan at $38.43 ($2.75/day). Buying one correctly-sized plan costs less than buying two smaller plans back-to-back.

The network section on this page lists the local operators for Bulgaria; the list does not say which one a phone joins. None of the 3 operators on that list carries a 5G label. A 5G label on that list is a technology label, not a speed. For a full-country itinerary, check the operator list before finalizing your plan.

Fixed data plans fit trips under 7 days in Bulgaria. At 1.5GB/day the 20GB plan at $17.03 covers a 7-day trip with data to spare. Unlimited for 7 days costs $16.14, with full speed for the first 2 GB each day, which is comparable to a fixed plan. Switch to unlimited if you stream video daily, work remotely, or use navigation continuously. A 14-day unlimited plan costs $29.34 ($2.10/day), with full speed for the first 2 GB each day.
