Best eSIM for Bulgaria (2026): Prices, Networks and Which Plan to Buy

The best eSIM for Bulgaria on price is Wayfarro at every size we compared, and the gap is widest on unlimited plans. Seven days of unlimited data costs $21 with Wayfarro, $25 with Nomad and $26.50 with Airalo. On fixed data, 1GB for 7 days is $4 at Wayfarro against $4.50 at Nomad, and 5GB for 30 days is $7.50 against $12.50. Wayfarro's prices come straight from its store; Nomad's and Airalo's were checked in October 2026.

Bulgaria changed more for travelers in the last two years than most of Europe: it joined Schengen fully in January 2025 and adopted the euro on 1 January 2026. The roaming rules didn't change for anyone arriving from outside the EU, though, so a Bulgaria eSIM is still the cheap way to stay online from Sofia to the Black Sea.

How to read this table: Wayfarro is the cheapest or level on every row, with Nomad matching it at 50GB and on 3-day unlimited. Wayfarro is the only one of the three with a 1-day plan and 2GB plan, and it has the cheapest 30-day unlimited plan. A dash means the provider doesn't sell that exact plan, or we couldn't confirm its US-dollar price. Airalo's Bulgaria page showed only unlimited plans when we checked.

The unlimited rows for Wayfarro are its Unlimited Lite plans: 1GB a day at full speed, then 512 kbps until the next day. Wayfarro also sells Unlimited Essential (1GB a day, then 1.25 Mbps) and Unlimited Plus (2GB a day, then 2 Mbps). Seven days costs $22 on Essential and $25 on Plus. Nomad's page says its unlimited plans give 2GB a day at 4G/5G and 1 Mbps after that; Airalo's says full speed for the first 3GB each day, up to 20 Mbps, then 1 Mbps.

Euro, Schengen and roaming: what changed

Bulgaria now pays in euros and sits inside Schengen, but neither changes what your phone does. EU roaming at home rates comes from EU membership, which Bulgaria has had since 2007, so an EU or EEA SIM already roamed here for free. Everyone else, from the US, UK, Canada, Australia or Asia, pays their carrier's daily rate or nothing at all, and that's where an eSIM earns its keep.

What the two changes do affect:

• Land borders from Greece and Romania no longer have passport queues, so a bus from Thessaloniki to Sofia or a drive over the Danube bridge from Romania is quicker. Your eSIM has nothing to do with the border, but a regional plan keeps working across it.
• Prices are in euros, so there's no lev to get your head around. Card payments are everywhere in cities; small coastal and mountain places still like cash.

If Bulgaria is one stop on a bigger route, Wayfarro's Europe plan covers Bulgaria along with Greece, Romania, Serbia and Turkey on one eSIM, and when we checked, its 1GB and 7-day unlimited prices were level with the Bulgaria-only plan. It doesn't cover North Macedonia, so a Sofia–Skopje trip needs the Balkans plan instead.

Which is the best eSIM for Bulgaria for your trip?

Pick by how long you're staying and how much you'll stream:

• A long weekend in Sofia or Plovdiv: 1GB for 7 days at $4 covers maps, messaging and photos if you're on hotel Wi-Fi in the evenings. Nomad's 1GB is $4.50.
• A week on the Black Sea coast: 5GB for 30 days at $7.50, or the 7-day unlimited plan at $21 if you'll post video from the beach every day. Both are cheaper than the equivalent at Nomad or Airalo.
• A ski week in Bansko or Borovets: The 10GB plan at $12. Lift-side video eats data, and 10GB is the first size that feels relaxed for a week.
• A month working remotely: The 20GB plan at $19 or 30-day unlimited at $45. Bansko has become a digital-nomad base, and the 30-day unlimited plan is where Wayfarro's gap over Airalo is largest.
• Bulgaria plus Greece, Turkey or Romania: the Europe plan above, or build the route in the Trip Builder.

Networks and coverage in Bulgaria

Bulgaria has three networks: A1, Vivacom and Yettel. A1 is the largest, with about 3.9 million subscribers at the end of 2025, followed by Vivacom with about 3.3 million and Yettel with about 3.2 million. All three run 4G nationwide and 5G in the 700 MHz and 3600 MHz bands. Yettel is the old Telenor and Globul network, so older guides that mention Telenor mean Yettel.

Nomad puts you on Vivacom and Yettel; Airalo on Vivacom. Wayfarro's plan page doesn't name its Bulgarian partner, so you'll see which network you're on when you land.

Where coverage matters:

• Sofia: Strong everywhere, including the four-line metro, which has 50 stations and runs out to the airport.
• The Black Sea coast: Varna, Golden Sands, Burgas, Sunny Beach and Nesebar are all well covered, and the resorts are at their busiest from late May to early October, when the towers are also at their busiest. Speeds dip on August evenings along the Sunny Beach strip.
• Rila and Pirin mountains: The resorts of Bansko and Borovets are fine. The hiking trails above them are not: the Seven Rila Lakes sit between 2,100 and 2,500 metres and the trail to Musala, at 2,925 m the highest peak in the Balkans, has long stretches with no signal. Download the route first.
• Plovdiv and Veliko Tarnovo: Both well covered, including the old towns. The highway between Sofia and Plovdiv, 144 km, is fine the whole way.
• The Danube and the north: Coverage follows the towns and main roads and thins out between them.

How to set up an eSIM for Bulgaria

Even the best eSIM for Bulgaria needs one setting switched on when you land. Install at home on Wi-Fi, then:

1. Check your phone is unlocked and supports eSIM. iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy phones do.
2. Install before you fly. Scan the QR code or tap the install link. The step-by-step install guide covers iPhone and Android.
3. Label it "Bulgaria" so it's easy to pick in settings.
4. When you land, set the Bulgaria eSIM as your mobile-data line and turn on Data Roaming for it. Travel eSIMs technically roam, so data won't connect without this.
5. Keep your home SIM on for calls and texts with its data roaming off, so bank codes still arrive.

With Wayfarro, your plan's validity starts when the eSIM first connects in Bulgaria, not when you install it, and you can top up the same eSIM without reinstalling.

Bulgaria on the ground: airports, coast and mountains

Three airports see nearly all visitors. Sofia Airport is 10 km east of the city centre, passed 8 million passengers in 2025 and is a base for Ryanair and Wizz Air, so many of Bulgaria's cheapest fares land here. Burgas Airport is about 10 km from Burgas and serves the south-coast resorts; Varna Airport is 10 km from Varna and serves Golden Sands and the north coast. Both coastal airports are seasonal, busiest from late May to early October.

A few things worth knowing:

• Sofia's metro runs to the airport. Terminal 2 has its own station, so you can be in the centre in about 20 minutes once your eSIM connects.
• Free Wi-Fi is decent in Sofia and Plovdiv cafés but patchy on the coast and in the mountains. Don't plan on it for maps.
• Translation apps earn their place. Bulgarian uses the Cyrillic alphabet, and outside Sofia and the resorts, menus and bus timetables are often Cyrillic only. The camera translator on your phone needs data.
• Day trips cross borders. Sofia to Skopje, Plovdiv to Edirne in Turkey and Varna to Constanța in Romania are all common. Turkey and Romania are on Wayfarro's Europe plan; North Macedonia isn't, so check before you rely on one eSIM.

Bottom line

The best eSIM for Bulgaria in this comparison is Wayfarro: cheapest or level on every plan, and the only one with 1-day and 30-day unlimited options at these prices. Nomad is a fair alternative at 50GB and on 3-day unlimited, where the two are level, and it names its networks. Airalo costs more at every unlimited length. Whichever you choose, install it at home and turn on data roaming when you land. See Wayfarro's Bulgaria eSIM plans. Continuing south?
