Best eSIM for Bulgaria

Bulgaria runs on two seasons and both are hard on a phone. In winter it is Bansko and Borovets, where you are checking lift status and weather on a cold chairlift; in summer it is Sunny Beach and Sozopol on the Black Sea, or Sofia and Plovdiv for a city weekend. Between them sit long drives past Veliko Tarnovo and the Rila Monastery on roads where the map is doing the work. Sofia (SOF), Varna (VAR) and Burgas (BOJ) all handle a lot of seasonal charter traffic, and the arrivals halls at Burgas and Varna in July are not where you want to be queueing for a SIM. Installing a travel eSIM before you fly removes that step completely.

Size the plan for the shape of the trip. A ski week uses less data than it feels like, mostly messaging and weather, whereas a driving holiday through the interior keeps navigation open for hours. City breaks in Sofia and Plovdiv sit in between and lean on transport apps and restaurant bookings. 5G is available in the larger cities, so a modern handset will see it in Sofia and Varna, while 4G carries the mountains and the coast. Check the plan card for hotspot if you are working remotely, which a lot of visitors to Bansko now do. No Bulgarian number is needed; your home SIM stays in the phone for one-time passwords. If Bulgaria is part of a wider trip through Romania, Greece or Serbia, compare this with a Europe regional plan. The device page confirms compatibility.

Bulgaria is served by A1 Bulgaria, Yettel Bulgaria and Vivacom, and your eSIM attaches to a partner among them automatically. Coverage is good nationally by regional standards: strong across Sofia, Plovdiv, Varna and Burgas, along the Black Sea coast, and on the motorways linking them. 5G is live in the main cities. The Sofia metro has coverage in the stations. Signal thins in the Rila and Pirin mountains away from the resorts, on the forest roads of the Rhodopes, and in some of the deeper Balkan range passes.

• Sofia — dependable citywide, including the metro stations and Vitosha.
• Plovdiv — strong in the old town and along the main street.
• Varna and Burgas — reliable through the resorts and along the coast road.
• Bansko — good in the town and on the gondola, weaker high on the pistes.
• Veliko Tarnovo — solid; the surrounding village roads are patchier.

If your home carrier is in the EU, check your allowance first, because Bulgaria may already be part of it. Travellers from India, the UK, the Gulf or North America gain the most from the eSIM, and it is the least effort at a busy charter terminal in season.

1. Pick a plan above; the QR code and instructions arrive by email in minutes.
2. iPhone on iOS 17.4 or later: use the install link. Otherwise Settings, Mobile Data, Add eSIM. On Android: Settings, Connections or Network, SIM manager, Add eSIM and scan.
3. Install at home on Wi-Fi and label the line Bulgaria.
4. Turn Data Roaming on for the eSIM line and mobile data off on your home SIM.
5. On landing at Sofia, Varna or Burgas, select the eSIM as your data line before you find the transfer coach.
6. The validity period starts at that first connection.

Install a few days ahead on home Wi-Fi, when there is time to sort out a problem if one appears. Because the plan starts at the first connection in Bulgaria, installing early costs nothing at all. Keep the line off during a stop in Vienna, Istanbul or Munich. Switch it on at the gate after landing, so the resort transfer details are on screen straight away.
