Does eSIM Work in Bulgaria?

Yes, eSIMs connect seamlessly to Bulgaria’s three major local carriers: A1 Bulgaria, Yettel Bulgaria, and Vivacom. All three offer excellent coverage throughout the country, including in rural areas and along highways.

• Cities: Excellent 4G and expanding 5G coverage in Sofia, Plovdiv, Varna, Burgas, and major tourist towns. 100% of the population has access to 4G, while 89% has access to 5G.
• Rural areas and mountains: Coverage is generally good, but can get patchy in remote mountain regions like the Rila Mountains, Pirin National Park, and the Balkan range. The ski resort of Bansko has solid coverage, but hiking trails above 2,000 meters may lose signal.
• Known weak spots: Remote hiking trails in the Rila and Pirin mountains often have no signal at all.
• Offline maps recommendation: Download Google Maps or Maps.me offline before heading into mountainous areas. This is essential if you’re hiking in national parks or driving through remote regions.

eSIM vs Local SIM in Bulgaria — Which Is Better?

Let’s be honest: an eSIM isn’t automatically the winner, especially for longer stays or heavy data use.

• Setup: International eSIM is set up before you travel and takes minutes. A local SIM requires finding a store or kiosk on arrival. Local eSIMs from Yettel, A1, and Vivacom can also be purchased online and installed via QR code.
• Price: Local SIMs offer incredible value — 25GB from 20 BGN (~€10). International eSIMs start from roughly $4 for 1GB.
• Data amount: Local SIMs offer massive data packages (25GB–100GB). International eSIMs offer smaller, fixed plans.
• Phone calls: Most eSIMs are data-only. Local SIMs can include a local number for calls and texts if you register with ID.
• Works on arrival: International eSIM works instantly. Local eSIM requires online purchase or a store visit.
• Flexibility: International eSIM is a fixed plan. Local SIMs can be topped up anytime at many locations or via app.

Who should choose an international eSIM: Short trips under one week, weekend city breaks, and travelers who want the convenience of having data the moment they land.

Who should get a local SIM or local eSIM: Stays of one week or more, heavy data users, and anyone on a tight budget. Local prepaid eSIMs from Yettel, A1, or Vivacom offer incredible value — 25GB for around €10 is unbeatable. Yettel’s local eSIM can also be purchased online and installed via QR code before arrival, giving you the best of both worlds: massive data, local network coverage, and no store visit.

How to Set Up Your eSIM for Bulgaria

1. Check compatibility: Make sure your phone is eSIM-compatible and network-unlocked. Most iPhones from XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer support it.
2. Buy the eSIM: Purchase your chosen plan from a provider before you travel. You’ll usually get a QR code via email. Local eSIMs like Yettel’s can also be ordered online and installed via QR code.
3. Install via QR code or app: Scan the QR code in your phone’s settings to install the eSIM profile. It takes two to five minutes.
4. Set data roaming ON: When you land in Bulgaria, turn data roaming on for the eSIM line.
5. Keep your home SIM active: Dual SIM works fine. You can keep your home SIM active for calls and texts while using the eSIM for data.

Common setup mistake: Activating the eSIM before you travel. Some plans start counting down their validity the moment you install them, so you might burn through your days before you even land. Check the provider’s policy before you activate.

eSIM Tips for Traveling in Bulgaria

• Buy a local eSIM online for the best value: If your phone supports eSIM, order Yettel’s prepaid eSIM online before arrival. You get 25GB for 20 BGN (~€10) with unlimited first 5 days — no queuing at the airport.
• Buy before you fly if using an international provider: Airport WiFi at Sofia, Varna, or Burgas can be unreliable for QR scanning on arrival. Install the eSIM while you have good WiFi at home or in your hotel.
• Download offline maps before landing: Use Google Maps or Maps.me to download Bulgaria’s map data. This is a lifesaver if you lose signal in the Rila or Pirin mountains.
• No ID registration for data-only plans: If you purchase a data-only SIM or eSIM from A1, Yettel, or Vivacom, you don’t need to register with your passport. This makes it quick and hassle-free.
• Keep your primary SIM for calls: If you want to keep your regular number for WhatsApp or iMessage, leave it active. Your phone will use the eSIM for data.
• Don’t stream on budget plans: A 1GB plan will disappear quickly if you start watching videos. For heavy data, choose a local 25GB plan or Holafly’s unlimited option.
• Check EU roaming if you’re visiting other countries: Local SIMs like Vivacom’s Data2Go include EU roaming data, which is handy if you’re also visiting Romania, Greece, or other neighboring countries.
