Cheapest eSIM for Bulgaria: everything you need to know
Bulgaria eSIM plans start at $2.21 for 1GB. The best per-GB value sits at 10GB for $8.06, which is $0.81/GB. Unlimited daily data costs $2.62/day with 2GB at full speed before throttling. A 30-day unlimited commitment drops to $2.15/day, 18% off the daily rate.
Airport SIM counters at Sofia (SOF) charge $5-10 for 5-10GB / 28 days. A prepaid eSIM at $2.21 undercuts both before you land.
The 10GB plan at $8.06 covers about 7 days at 1.5GB/day. For trips longer than 7 days, unlimited at $2.62/day avoids the need to buy multiple fixed plans. Heavy users above 3.2GB/day will exhaust fixed data faster, making unlimited worthwhile on shorter trips too.
Network coverage in Bulgaria
All providers connect through the same A1, Vivacom, and Telenor networks in Bulgaria. Carrier choice does not change your bill. Only the provider margin differs. A1 and Vivacom deliver 4G LTE regardless of which eSIM you buy.
How much data do you need in Bulgaria?
Most travelers over-buy. If you mainly use maps, translation apps and messaging, 1GB comfortably covers 5–7 days. Add daily social media and you'll want 3–5GB for a week. Only heavy users need 10GB or more.
When should you buy your Bulgaria eSIM?
Buy a few days before departure and install while you still have home Wi-Fi, but don't activate until you arrive. Most plans start counting from first connection, not purchase. Prices are stable week-to-week, so the plan ranked first in our table today is the best price.

Questions travelers ask before buying
What is the absolute cheapest eSIM for Bulgaria?
Bulgaria's most affordable eSIM is the 1GB plan at $2.21, which works out to $2.21/GB. Airalo holds the lowest-price position for this destination (Nomad averages $0.74/GB globally, the lowest of the four providers we track). Prices are fixed year-round with no seasonal markup. For the best per-GB rate, the 10GB plan at $8.06 ($0.81/GB) saves $1.40 per GB versus the entry plan.
When does unlimited data beat a fixed plan for Bulgaria?
Bulgaria offers unlimited eSIM data at $2.62/day. The best fixed plan runs $0.81/GB (10GB plan at $8.06), which covers about 7 days at 1.5GB/day. Beyond that, unlimited at $2.62/day is the practical option. Example: a 7-day trip at 1.5GB/day needs about 11GB. The 20GB plan costs $17.03, while 7-day unlimited costs $16.87. Unlimited saves $0.16. For trips beyond 7 days, unlimited is the better deal in Bulgaria.
Is a local prepaid SIM cheaper than an eSIM in Bulgaria?
Prepaid SIM costs in Bulgaria varies by airport vendor and carrier. A travel eSIM starts at $2.21 for 1GB with no airport queue, no activation counter, and instant delivery. The convenience premium over the cheapest local SIM is typically $2 to $5 for a week-long trip. If the local SIM requires ID registration, the time cost alone favors the eSIM.
Does the cheapest eSIM provider use a slower network in Bulgaria?
No. Budget providers like Nomad and Airalo route Bulgaria plans through the same tier-one local carriers (A1 and Vivacom) as premium-priced alternatives. The price gap reflects provider margin, not network quality. 4G LTE speeds are consistent across all four compared providers for Bulgaria. The only tested differences are activation speed and support response time, not the data connection itself.
Does the cheapest Bulgaria eSIM support hotspot tethering?
Airalo and Nomad allow full-speed hotspot tethering on all Bulgaria plans. Holafly restricts hotspot to about 1GB/day on its unlimited plans. Saily supports tethering with no stated cap. For budget tethering in Bulgaria, Airalo's 1GB plan at $2.21 gives the lowest per-GB cost with hotspot included. Use hotel WiFi for heavy downloads to stretch the plan further.
Is an eSIM cheaper than EU roaming in Bulgaria?
If your home carrier is inside the EU, roaming is free under EU rules, so no eSIM is needed. If you are visiting from outside the EU, a Bulgaria eSIM at $0.81/GB beats carrier roaming rates of $10 to $15/day. Non-EU travelers save 80-95% with an eSIM. A 1-week trip under carrier roaming runs $70 to $105; the cheapest eSIM for the same week runs a fraction of that.
Can I use one cheap eSIM across multiple European countries including Bulgaria?
Yes. Airalo's Eurolink bundle covers 39 European countries on a single eSIM starting at $5, which is cheaper than buying separate plans for each destination. For Bulgaria only, a country-specific plan at $2.21 for 1GB is the cheapest option if you stay in one country.
What is the per-GB cost breakdown for Bulgaria eSIMs?
Bulgaria eSIM cost per gigabyte: 1GB at $2.21/GB, 3GB at $1.16/GB, 5GB at $1.04/GB, 10GB at $0.81/GB, 20GB at $0.85/GB. The 10GB tier at $8.06 gives the lowest per-GB rate. Buying 10GB instead of the smallest plan saves $1.40 per GB, which adds up on longer trips.
Which network does the cheapest Bulgaria eSIM use?
The cheapest plans for Bulgaria route through A1, with some providers using Vivacom. Both deliver 4G LTE speeds. Network quality between the two is nearly identical. The price difference is the provider's margin, not carrier performance.
Is unlimited data worth the price in Bulgaria?
Unlimited daily data in Bulgaria costs $2.62/day (2GB at full speed). At $0.81/GB on the 10GB fixed plan, unlimited only saves money if you use more than 3.2GB per day. Most travelers use 1 to 2GB/day, so the fixed plan is cheaper for typical use.
