The 60-second verdict
Flysimio sells 5 GB for 30 days in Bulgaria at $8.00, with access to A1, Vivacom and Telenor. Airalo's cheapest 30-day Bulgaria plan is $71.00, because they sell the country as unlimited-only. Our 1 GB / 7-day plan at $2.25 covers a Sofia city break.
Bulgaria is genuinely one of Europe's better-value destinations, and that extends to connectivity — it has consistently strong fixed and mobile internet, and Sofia has become a real remote-working base on the back of it.

Bulgaria's networks
A1 Bulgaria, Vivacom and Yettel (formerly Telenor) are the three operators, and all three have solid 4G nationally with 5G across the major cities. Coverage is good along the road network and in the ski resorts; the gaps are in the Rhodope and Pirin mountain interiors.
Skiing: Bansko, Borovets and Pamporovo
Bulgaria is one of the cheapest places to ski in Europe, and the season runs roughly December to April. All three main resorts have coverage in the resort villages and on the main lift lines. What thins out is the off-piste and the back bowls, plus the mountain roads up — the drive to Bansko from Sofia is fine, but the higher switchbacks toward Borovets can drop.
Coverage by destination
- Sofia — 5G across the centre and Vitosha Boulevard; the metro is covered, and the airport has strong signal.
- Plovdiv — 5G through the Old Town and Kapana district.
- Black Sea coast (Varna, Burgas, Sunny Beach, Nessebar) — well covered, congested in peak August.
- Bansko, Borovets, Pamporovo — covered in resort and on the main lifts.
- Rila Monastery — coverage at the monastery and on the access road; thinner in the surrounding valley.
- Rhodope and Pirin interiors — real gaps. Download offline maps if you are hiking or driving the back roads.
How much data do you need?
A week in Sofia and Plovdiv runs 2–3 GB for most travellers. Buy 3 GB at $5.75 for a week, or 10 GB at $15.25 if you are working remotely from Sofia for a month.
Setting it up
- Buy and install on Wi-Fi before you travel.
- Switch the line on at Sofia airport and enable Data Roaming for that line only.
- Turn Data Roaming off on your home line.
- Download offline maps before heading into the Rhodope or Pirin ranges.
- Bulgaria uses the lev, not the euro, despite being in the EU.
Frequently asked questions
What is the best eSIM for Bulgaria?
Flysimio — 5 GB for 30 days is $8.00 with access to A1, Vivacom and Telenor, against $71.00 for Airalo's cheapest 30-day Bulgaria plan, which is unlimited-only.
Is there mobile coverage in Bansko?
Yes, in the resort village and on the main lift lines. Coverage thins off-piste and on the higher mountain roads, so download offline maps if you are venturing beyond the marked pistes.
Do I need an eSIM for Bulgaria if I am from the EU?
Probably not. Bulgaria is an EU member, so roam-like-at-home allowances from an EU SIM apply. Check your existing plan before buying anything.
Does Bulgaria use the euro?
No. Bulgaria is in the EU but still uses the Bulgarian lev (BGN). Card acceptance is good in Sofia and the resorts, but carry some cash for smaller towns.
How much data do I need for Bulgaria?
About 2–3 GB for a week covering Sofia and Plovdiv. Bulgaria has consistently strong internet and widespread Wi-Fi, so a 3 GB plan at $5.75 is comfortable for most trips.
