Detailed provider reviews for Bulgaria

Airalo

Recommended

Airalo's Bulgaria plan ('Bulgarsko') runs on A1 Bulgaria, the operator with the largest footprint and the strongest coverage along the Black Sea coast. The 5 GB / 30-day plan is the practical pick for a typical week including Sofia, Plovdiv, and either a beach extension or the mountains. Airalo's Eurolink regional plan is also worth considering if your trip extends to Greece, Romania, or Serbia.

Pros

Yesim

Cheapest

Yesim is exceptional value in Bulgaria. The $1.50 / 1 GB / 3-day plan is the cheapest weekend option in Europe, and the $12 / 10 GB / 30-day plan covers any reasonable Bulgaria trip with room to spare. Network-hopping between A1, Vivacom, and Yettel works well in this country because all three have similar coverage quality. The unlimited plan is excessive for short trips but suits anyone basing themselves in Sofia for weeks.

Pros
  • $1.50 / 3-day plan is the cheapest in Europe for a quick trip
  • $12 / 10 GB is best value for any Bulgaria itinerary
  • Network-hopping works well across A1, Vivacom, and Yettel
  • Unlimited plan suits month-long Sofia stays
Cons
  • iOS-only VPN feature
  • Less name recognition than Airalo
  • Unlimited has a soft cap around 70 GB
  • Unlimited price ($27.60) is high for short trips

Saily

Privacy-focused

Saily uses A1 Bulgaria similar to Airalo, with a $1 cheaper 1 GB tier and the built-in ad blocker. The blocker is useful on Bulgarian news sites (Dnevnik, 24chasa) and the local food delivery apps (Foodpanda, Glovo) which run heavy advertising. The 3 GB / 30-day plan at $7.99 is a fair pick for a typical Bulgaria week, though Yesim's equivalent pricing is still better at the larger plans.

Pros
  • Same A1 Bulgaria network as Airalo for less money
  • Ad blocker trims data on Bulgarian news and delivery apps
  • 30-day window on 3 GB suits typical trips
  • Nord Security parent for privacy-conscious travellers
Cons
  • Yesim is still cheaper at the 10 GB tier
  • No regional Europe plan
  • Ad blocker can interfere with Bulgarian banking apps
  • No 10 GB option in the lineup

Drimsim

Backup only

Drimsim's pay-as-you-go in Bulgaria works out to around $3/GB, which is competitive against Airalo's smaller plans but expensive compared to Yesim's larger tiers. As a primary plan it's only sensible if Bulgaria is one stop on a multi-country Balkan loop. The no-expiry balance suits irregular travellers who visit Eastern Europe occasionally.

Pay-as-you-go
~$3.00/GB
No expiry
Balance never expires
Pros
  • Single eSIM for a Balkan loop including Serbia, Macedonia, and Albania
  • Balance never expires — convenient for repeat visitors
  • No commitment to a 30-day window
  • Reliable backup if your primary fails on arrival
Cons
  • More expensive per GB than Yesim's larger plans
  • Not the cheapest option for any specific use case in Bulgaria
  • Network choice depends on what Drimsim parks on
  • Top-up flow is dated

How much data do you need in Bulgaria?

Bulgaria is one of the lower-data destinations in Europe for tourists, mostly because the country is compact and Wi-Fi is widely available in cafés, hotels, and resorts. A typical Sofia city break or Black Sea beach week leans heavily on Wi-Fi for evenings and uses cellular mainly for getting around. The exception is the mountains: trips to Rila Monastery, the Seven Rila Lakes, or the Pirin range push usage up because navigation matters more and Wi-Fi isn't around.

Bulgarian cyrillic is the secondary navigation challenge — Google Translate camera mode is useful for reading menus and street signs outside the main tourist areas, and that's a steady drain on data when you use it constantly. Sunny Beach and Bansko ski resort have dense tourist Wi-Fi but the surrounding villages don't.

Our recommendation: 1 GB for a Sofia weekend. 3 GB for a week including Plovdiv or Veliko Tarnovo. 5 GB for a Black Sea coastal trip or a multi-region tour including the mountains.

Network coverage in Bulgaria

Bulgaria has three operators: A1 Bulgaria (the largest, formerly Mobiltel), Vivacom (the former state telecom), and Yettel Bulgaria (formerly Telenor BG, now part of PPF Group). All three have 4G LTE blanketing the entire country and 5G live in Sofia, Plovdiv, Varna, Burgas, and Stara Zagora. Coverage gaps are rare and mostly limited to deep parts of the Pirin and Rila mountain ranges.

A1 Bulgaria has the largest footprint and tends to be strongest along the Black Sea coast and in the major tourist resorts. Vivacom is competitive in Sofia and the south. Yettel covers cities well but has slightly weaker rural coverage than the other two. Most international eSIMs run on A1 Bulgaria, including Airalo and Saily.

Tips for using an eSIM in Bulgaria

Bulgaria is in the EU roaming zone. A Europe regional eSIM (Airalo Eurolink, Yesim Europe) works here without extra setup. If your trip combines Bulgaria with Romania, Greece, or Serbia, a regional plan is cleaner than country-specific options. Bulgaria isn't yet in Schengen for land borders (though it joined for air travel in 2024) so you may still see passport checks at the Romanian and Greek borders.

Bulgarian eSIM pricing is some of the cheapest in Europe. Yesim's $1.50 / 3-day plan is unbeatable for a Sofia weekend, and the $12 / 10 GB / 30-day plan is enough for almost any Bulgaria trip. The local market is competitive and that pulls international eSIM pricing down too.

Sunny Beach can get congested in summer. The Black Sea resort towns (Sunny Beach, Golden Sands, Albena) attract massive tourist volumes in July and August, and cellular networks get strained at peak hours. A1 Bulgaria handles the load best because of its denser tower footprint along the coast.

Rila and Pirin mountains have signal at the trailheads, not above. Mountain refuges and the higher trekking routes around Mount Musala or the Seven Rila Lakes lose signal completely. Download offline maps before any hike and don't rely on cellular for emergency contact above the treeline.

Why eSIM is the best choice in Bulgaria

Bulgarian local SIMs are easy to buy and competitively priced — A1 and Vivacom both sell tourist plans at supermarkets and kiosks for around 15-20 leva. The catch is that registration requires a passport scan and the activation steps are typically only in Bulgarian. For a short trip, the time saved by an eSIM activated before you land outweighs the small price difference.

The other reason: Bulgaria fits naturally into multi-country Balkan trips. A regional Europe eSIM covers Bulgaria, Romania, Greece, and the rest of the EU on a single plan, which is much simpler than juggling three SIMs across an itinerary.

Frequently asked questions

Yes — Bulgaria has been in the EU roaming zone since joining the EU. Any European regional eSIM (Airalo Eurolink, Yesim Europe) works in Bulgaria without extra setup or charges. Note that Bulgaria joined Schengen for air travel only in 2024 — land border crossings into Greece, Romania, or Serbia may still involve passport checks even though cellular roaming works seamlessly.
A1 Bulgaria has the strongest footprint along the Black Sea coast, including in the major resort areas (Sunny Beach, Golden Sands, Albena, Sozopol) and the smaller fishing villages between them. Vivacom is competitive in Burgas and Varna cities. Yettel is fine in the resorts but slightly weaker in the rural coastal areas. Airalo and Saily both use A1 Bulgaria for their plans here.
At Rila Monastery itself yes — there's reasonable coverage from all three operators near the visitor area. The hike up to the Seven Rila Lakes loses signal as you climb, and the upper lakes themselves are essentially cellular dead zones on every Bulgarian network. Download offline maps and don't rely on cellular for emergency contact above the treeline.
Local Bulgarian tourist SIMs from A1 or Vivacom cost around 15-20 leva (USD 8-11) for plans similar to a 5 GB eSIM. The price difference is small but the local SIM requires a passport scan and the activation is typically in Bulgarian only. For trips under two weeks, the eSIM premium buys you working data the moment you land at Sofia airport.
Yes — A1 Bulgaria, Vivacom, and Yettel all have 5G live in Sofia, Plovdiv, Varna, Burgas, and Stara Zagora. Coverage in smaller towns is mostly 4G LTE. All four eSIMs handle 5G automatically — when you're in a covered area, your phone picks the fastest available network without intervention, with no extra plan or activation step required.
