Where to Buy a SIM Card in Bulgaria: Airports, Shops & Online

Bulgaria joined the Schengen Area in early 2024, which means border crossings are now faster and smoother for most visitors — but it also means you move through arrivals more quickly than before, sometimes without realizing you’ve passed the last convenient spot to buy a SIM card. Land in Sofia, clear passport control in under ten minutes, and suddenly you’re outside in the taxi queue with no data, no map, and no way to confirm your hotel address. In 2026, that situation is entirely avoidable, but only if you know exactly where to look and what to bring with you.

The ID Registration Rule — What Every Visitor Must Know Before Buying

Since 2015, Bulgarian law requires mandatory registration for every SIM card purchase, including prepaid options. This rule has not relaxed in 2026 and shows no sign of changing. Every single SIM card — whether you buy it at a slick airport kiosk, a supermarket counter, or online — must be linked to a valid identity document before it can be activated.

For foreign visitors, a valid passport is the universally accepted document. EU citizens may sometimes register with a national ID card, but in practice, staff at kiosks and smaller shops are far more comfortable processing a passport. Bring your passport. Keep it in your carry-on, not your checked luggage, so it is in your hands the moment you land.

The registration process itself is straightforward. In an official store or airport kiosk, it takes roughly five to ten minutes. A staff member enters your passport details into the operator’s system, issues the SIM or eSIM QR code, and you are done. There is no fee for registration beyond the cost of the package itself. The friction is minimal as long as you have the right document ready.

The one situation that causes genuine problems is buying a SIM from a newsstand or a small kiosk that cannot perform the registration on the spot. The SIM exists as a physical card, but it cannot be activated until you take it to an official operator store. For tourists who buy from an unregistered point of sale, this means an extra trip across town — not ideal when you have just arrived and need directions.

The Three Networks at a Glance — A1, Vivacom, and Yettel Compared

Bulgaria has three main mobile network operators: A1 Bulgaria, Vivacom, and Yettel Bulgaria. All three offer solid 4G LTE coverage across the country and expanding 5G networks in major cities and along the main transport corridors. For a tourist in 2026, the differences between them are relatively minor — you will not go seriously wrong with any of the three. That said, here is how they compare on the metrics that matter most.

A1 Bulgaria

A1 is the former M-Tel, now a subsidiary of the Austrian A1 Telekom Austria Group. Its tourist-focused package is the A1 Tourist Go, which costs BGN 24.99 (approx. EUR 12.78) and includes 25 GB of 4G/5G data, 500 national minutes, and 100 national SMS, all valid for 30 days from activation. A1 generally has strong urban and mountain coverage, which is useful if you are heading to the Rila or Rhodope Mountains. You manage the account through the My A1 app on iOS or Android, and top-ups are available through the app, ATMs, scratch cards at petrol stations, and directly on the website at www.a1.bg.

Vivacom

Vivacom, part of United Group, offers the Vivacom Easy Travel pack at BGN 27.99 (approx. EUR 14.31). For the slightly higher price, you get 30 GB of data and unlimited national calls — a better deal if you plan to make a lot of local phone calls. Validity is also 30 days. Vivacom’s 4G and 5G network is reliable in Sofia, Plovdiv, Varna, and Burgas, and the operator has a solid presence along the Black Sea coast, which is relevant if you are visiting during summer. The My Vivacom app handles account management, and the website is www.vivacom.bg.

Yettel Bulgaria

Yettel was formerly Telenor Bulgaria. Despite being acquired by United Group, it still operates under the Yettel brand in 2026. The Yettel Tourist Starter pack is the most affordable of the three tourist-specific packages at BGN 22.99 (approx. EUR 11.75), offering 20 GB of data, 400 national minutes, and 50 national SMS over 30 days. If you are on a tighter budget and primarily need data rather than calls, Yettel is worth considering. The Yettel App is available on iOS and Android, and the website is www.yettel.bg.

All three operators have significantly expanded their 5G networks since 2024. All tourist prepaid packages include 5G access where coverage is available, so if you have a 5G-compatible handset, you will benefit from faster speeds in Sofia, Plovdiv, Varna, and Burgas without paying anything extra.

Buying at Sofia Airport — Terminal 2 vs. Terminal 1 Reality Check

Sofia Airport (SOF) handles the vast majority of international arrivals to Bulgaria. It is the single best place in the country to buy a SIM card immediately upon arrival, assuming you know which terminal to look in.

Terminal 2 is where international and most Schengen flights arrive. All three operators — A1, Vivacom, and Yettel — have dedicated kiosks or small shops in the arrivals area, positioned after baggage claim and customs, near the main exit. The kiosks are easy to spot, usually brightly lit with the operator’s branding, and are typically open from 08:00 to 22:00 daily, timed to cover most international flight arrivals. Staff at these kiosks generally speak English and are accustomed to helping tourists. The entire process of choosing a package, registering your passport, and activating your SIM takes about ten minutes.

The tourist packages available at the airport kiosks — A1 Tourist Go, Vivacom Easy Travel, Yettel Tourist Starter — are generally the same packages and prices you would find in city shops. There is no meaningful airport premium on the tourist-specific packs, though basic starter packs may vary slightly.

Terminal 1 is a different story. It handles low-cost and some domestic flights and has far fewer retail options. You may find a small newsagent that sells basic prepaid SIM cards, but mandatory ID registration is not available there. If you arrive at Terminal 1, the practical advice is to skip the newsstand and either head directly to your destination and find an official store there, or take the short walk or shuttle to Terminal 2 where the full kiosk setup is available.

The arrivals hall at Terminal 2 can feel chaotic after a long-haul flight — the buzz of competing taxi drivers, the hum of luggage wheels on polished floors, and families reuniting near the barriers. The operator kiosks are set slightly back from the main foot traffic. Look for them before you exit through the final sliding doors into the public waiting area.

Regional Airports — Plovdiv, Varna, and Burgas (What to Expect)

If you are flying directly into a regional Bulgarian airport, the situation is considerably less convenient than Sofia.

Plovdiv Airport (PDV) is small and has limited retail beyond a basic newsagent. There are no dedicated operator stores or kiosks. You may find basic prepaid SIM cards for sale, but you will not be able to complete mandatory registration on the spot. The sensible move is to wait until you reach Plovdiv city center, which is about 12 kilometres from the airport. Plovdiv has multiple A1, Vivacom, and Yettel stores within easy reach of the old town and main square.

Varna Airport (VAR) and Burgas Airport (BOJ) operate seasonally at high volume during the summer months of June through September, when charter and budget airlines flood the Black Sea coast with tourists. During this peak period, one or more of the three operators typically set up temporary kiosks in the arrivals hall. Outside of summer, these temporary setups disappear. If you are arriving at Varna or Burgas in autumn, winter, or early spring, assume no operator presence at the airport and plan to buy your SIM in the city after arrival.

For anyone arriving at a regional airport outside the summer season, the most practical solution in 2026 is to purchase and activate an eSIM before you travel, avoiding the airport kiosk question entirely.

Official Brand Stores — The Most Reliable Option in Any City

If you miss the airport kiosk or arrive at a regional airport, official operator stores in city centers are your best fallback. They are widely available across Bulgaria — not just in Sofia, but in Plovdiv, Varna, Burgas, Stara Zagora, Ruse, and most larger towns.

The advantages of buying in an official store are clear. Staff have full access to the operator’s systems and can handle registration, activation, and troubleshooting without shortcuts. You get the full range of available plans, including any current promotions that may not be listed on the website. In major cities, most staff in official stores speak conversational English.

Finding a nearby store is straightforward using each operator’s online store locator:

• A1: www.a1.bg/magazini
• Vivacom: www.vivacom.bg/bg/residential/shops
• Yettel: www.yettel.bg/en/shops

Stores in shopping malls tend to have longer opening hours, typically 10:00 to 21:00. Standalone high-street stores may close earlier, around 18:00 or 19:00 on weekdays. It is worth checking hours before you make the trip, particularly on Sundays.

One option that is easy to overlook: Bulgarian Posts (Български пощи) offices in smaller towns sell Yettel prepaid SIM cards and can perform the mandatory ID registration. If you are in a rural area or a smaller town where none of the three operators have a dedicated store, a larger post office branch is worth checking.

Electronics Chains, Supermarkets, and Newsagents — What They Can and Can’t Do

A variety of non-operator retail outlets sell prepaid SIM cards in Bulgaria, and it is important to understand exactly what they can and cannot do before you rely on them.

Electronics chains — primarily Technopolis and Technomarket, both found in most major cities and large shopping centres — stock prepaid SIM cards for all three operators and typically have staff who can assist with the ID registration process. These are a legitimate alternative to official brand stores, particularly if you are already visiting a shopping mall and want to avoid a separate trip to an operator outlet.

Supermarkets including Kaufland, Billa, Lidl, and the local chain Fantastico sometimes sell prepaid SIM cards at their customer service desks or in their electronics sections. Registration may be possible at larger branches, but the experience is slower and more variable than at a dedicated store. Staff are not always trained for this process. Treat supermarket purchase as a last resort rather than a first choice.

Newsagents and small kiosks — including the widespread Lafka chain — sell basic prepaid starter packs. They cannot, however, perform mandatory ID registration. The SIM card they hand you will not work until it has been registered at an official operator store. Buying from a newsagent and then walking to an operator store for registration is a two-step detour that most tourists find more hassle than it is worth. Avoid this route unless it is the only option available to you.

eSIM for Bulgaria — How to Get Connected Before You Land

The biggest practical change in Bulgarian SIM connectivity since 2024 is the widespread availability of prepaid eSIM from all three major operators. By 2026, all three operators offer tourist eSIM packages that can be purchased and activated entirely online, before you even board your flight.

eSIM eliminates the airport kiosk queue, the problem of arriving at a regional airport with no operator presence, and the complication of tracking down an official store while jet-lagged. If your phone supports eSIM — and most flagship Android and Apple devices released after 2021 do — this is the cleanest solution available.

Purchasing an eSIM Online

Each operator has a dedicated eSIM purchasing page for tourists:

• A1: a1.bg/eSIM-tourist — offers the A1 Tourist Go package (BGN 24.99 / approx. EUR 12.78) as an eSIM
• Vivacom: vivacom.bg/eSIM-travel — offers the Vivacom Easy Travel pack (BGN 27.99 / approx. EUR 14.31)
• Yettel: yettel.bg/eSIM-tourist — offers the Yettel Tourist Starter (BGN 22.99 / approx. EUR 11.75)

The process is consistent across all three:

1. Visit the eSIM tourist page for your chosen operator.
2. Select the tourist package.
3. Complete the online registration form and upload a clear scan or photo of your passport. Online ID verification takes one to two hours during business hours, and up to 24 hours at other times.
4. Pay by credit or debit card.
5. Receive an email with a QR code.
6. On your eSIM-compatible device, go to mobile settings, select “Add eSIM” or “Add Data Plan,” and scan the QR code.

You can complete steps one through five before you travel. On arrival in Bulgaria, simply turn off your home SIM’s roaming or set the Bulgarian eSIM as your data line. You will connect to the local network within minutes of landing.

eSIM can also be purchased in-store at any official operator location. The staff will provide a printed QR code or email it directly to you for immediate activation — useful if you prefer face-to-face assistance or if your online verification takes longer than expected.

2026 Budget Reality — What a Tourist SIM Actually Costs

Here is an honest breakdown of what you will spend on mobile connectivity in Bulgaria in 2026, across different spending levels.

Budget tier

The Yettel Tourist Starter at BGN 22.99 (approx. EUR 11.75 / approx. USD 12.70) is the entry point for a proper tourist package — 20 GB of data, 400 national minutes, 50 SMS, valid for 30 days. For most solo travellers who primarily need navigation, messaging, and casual browsing, this is more than enough data for a two-to-three week trip.

Mid-range tier

The A1 Tourist Go at BGN 24.99 (approx. EUR 12.78 / approx. USD 13.80) bumps data up to 25 GB and increases national minutes to 500. Suitable for travellers who video-call home regularly or stream music and maps heavily. The A1 network’s strong mountain coverage makes this a good choice for hiking trips in the Rila, Pirin, or Rhodope ranges.

Comfortable tier

The Vivacom Easy Travel pack at BGN 27.99 (approx. EUR 14.31 / approx. USD 15.50) offers 30 GB of data and unlimited national calls. If you are travelling with family, coordinating group activities, or spending significant time on the Black Sea coast where Vivacom’s network is particularly strong, the extra data and unlimited calls justify the modest price premium.

Top-up options are available across all operators. Physical scratch cards are sold at petrol stations and convenience stores for BGN 10 or BGN 20 increments. The My A1, My Vivacom, and Yettel apps all support in-app top-ups by credit or debit card. ATM machines at major Bulgarian banks also support top-ups for all three networks.

Basic starter packs exist from as little as BGN 4 to BGN 10 across the three operators, but these come with minimal pre-loaded data and require immediate top-up to be practically useful. They are not recommended for tourists who want to be connected from the first minute.

Free WiFi in Bulgaria — Where It Works and Where It Doesn’t

A local SIM gives you independence, but free WiFi is genuinely available and often reliable in Bulgarian cities. Knowing where it works and where it falls short helps you decide how much mobile data you actually need.

City centres: Sofia, Plovdiv, Varna, and Burgas all have municipal free WiFi networks in their central areas — branded as “Sofia Free Wi-Fi,” “Plovdiv Free Wi-Fi,” and similar. Speed and stability vary by location. In Sofia’s central pedestrian zone along Vitosha Boulevard, the connection is generally reliable enough for maps and messaging. In quieter parks or side streets, it can drop to frustratingly slow speeds.

Airports: Sofia Airport, Varna Airport, and Burgas Airport all offer free WiFi. At Sofia Airport, the free connection is available for a limited duration — typically two to four hours — or with extended access after simple registration. Enough to send messages and load directions while you wait at the kiosk to buy a SIM.

Accommodation: Almost all hotels, hostels, and guesthouses in Bulgaria include free WiFi as standard. This has been universal practice for years and remains true in 2026. In the countryside and smaller villages, the speed may be slower, but a connection will almost always be available.

Cafes and restaurants: The vast majority of Bulgarian cafes and restaurants offer free WiFi to customers. In Sofia, the aroma of freshly roasted coffee at a Vitosha Boulevard café comes with a password printed on your receipt without even asking. In smaller towns, a quick request to the staff will get you connected within seconds.

BDZ trains: Newer intercity BDZ trains on routes such as Sofia–Plovdiv, Sofia–Varna, and Sofia–Burgas have onboard WiFi, but it is intermittent and should not be relied on for anything time-sensitive. Older rolling stock has no WiFi at all. Intercity buses generally do not offer WiFi.

The practical takeaway: WiFi covers you well at your accommodation, in cafes, and in city centres, but the moment you are in transit — on a bus, driving through the countryside, hiking, or navigating a town you have never visited — you will want your own mobile data connection.

What Changed Since 2024 — New Networks, Better eSIM, Improved Packages

The Bulgarian mobile market has shifted noticeably since 2024, and some of those changes are directly relevant to tourists planning a trip in 2026.

eSIM went mainstream: The single biggest improvement. In 2024, prepaid eSIM for tourists was limited or available from only one operator. By 2026, all three operators offer prepaid eSIM as a standard option, with consistent online purchase processes including passport upload and digital verification. This is a genuine quality-of-life improvement for international visitors.

Online ID verification improved: The passport upload and verification processes on all three operator websites are faster and more reliable than they were in 2024. Verification now typically completes within one to two hours during business hours, down from what was sometimes a multi-day wait.

5G expansion: All three operators have extended their 5G footprints considerably. Sofia’s coverage is now near-comprehensive in built-up areas. Plovdiv, Varna, and Burgas also have solid 5G zones in their centres and along main roads. All tourist prepaid packages include 5G access where the signal is available.

Tourist packages became the default: Older prepaid plans with minimal data have largely been retired. The market has consolidated around tourist-friendly packages with meaningful data allowances (20–30 GB) and reasonable validity periods. This simplifies the decision for visitors — the tourist package is essentially the only sensible prepaid option now.

Minor price increases: Compared to 2024, tourist packages have increased by roughly BGN 2 to BGN 5 across the board. This reflects both inflation and the improved data allowances included in the packages. In absolute terms, the prices remain very competitive by European standards.

Common Mistakes That Leave Tourists Without Data

The same errors come up repeatedly among visitors who arrive in Bulgaria without a working SIM. Knowing them in advance takes less than two minutes to read and can save you hours of frustration.

• Leaving your passport in checked luggage. You cannot register a SIM without it. Keep your passport in your carry-on bag, always.
• Assuming Terminal 1 at Sofia Airport has operator kiosks. It does not. If you land at Terminal 1, head to Terminal 2 or a city store.
• Buying from a newsagent and expecting it to work. Newsagents cannot perform ID registration. The SIM will be inactive until you visit an official store.
• Ordering a physical SIM online for delivery to your hotel. Physical SIMs ordered online require delivery to a Bulgarian address, which takes two to five business days. Unless you have a fixed address and are staying long-term, eSIM is the only sensible online option for tourists.
• Not checking eSIM compatibility before travelling. eSIM requires a compatible device. Check your phone’s specifications before purchasing. Most flagships from Apple, Samsung, and Google released after 2021 support eSIM, but some budget Android phones do not.
• Arriving outside airport kiosk hours. If your flight lands after 22:00, the airport kiosks may be closed. Purchase your eSIM online before travel, or use the airport WiFi to get through the first night and visit a store the following morning.
• Forgetting to set the Bulgarian eSIM as your active data line. After scanning the QR code, go into your phone’s mobile data settings and confirm that the Bulgarian eSIM — not your home carrier — is selected as the data SIM. This step catches out even experienced travellers.

Frequently Asked Questions

Do I need a Bulgarian SIM card, or can I just use roaming from home?

Roaming works in Bulgaria, but costs vary significantly depending on your home country and carrier. Visitors from EU countries benefit from regulated roaming rates, but non-EU travellers — particularly from the US, UK, Australia, and Canada — often face expensive data charges. A local tourist SIM or eSIM starting from BGN 22.99 (approx. EUR 11.75) gives you 20–30 GB of local data at a fixed, predictable cost, which is almost always better value for a stay of more than a few days.

Can I buy a Bulgarian SIM card without a passport?

No. Bulgarian law requires mandatory ID registration for all SIM cards, including prepaid, since 2015. A valid passport is universally accepted. EU citizens may use a national ID card in some stores, but a passport is strongly recommended to avoid any complications. Without a valid ID document, no operator can activate a SIM or eSIM on your behalf.

Which Bulgarian mobile operator has the best coverage in rural areas and mountains?

All three operators — A1, Vivacom, and Yettel — provide good 4G LTE coverage in cities and along main transport routes. In more remote areas, such as the Rila, Pirin, and Rhodope mountain ranges, A1 is generally regarded as having the widest rural coverage, though all three networks have gaps in deep valleys and high-altitude terrain. For hiking trips, download offline maps before you leave your accommodation.

How do I top up a Bulgarian prepaid SIM while travelling?

Top-up options are widely available. The easiest method is through the operator’s own app — My A1, My Vivacom, or the Yettel App — using a credit or debit card. Alternatively, scratch cards in denominations of BGN 10 and BGN 20 are sold at petrol stations, convenience stores, and some supermarkets. ATMs at major Bulgarian banks also offer top-up functionality. Top-ups activate within minutes of payment.

Is it worth buying a global travel eSIM (e.g., Airalo) instead of a local Bulgarian SIM?

Global travel eSIM providers like Airalo offer data-only plans for Bulgaria at competitive prices, and they are convenient if you are visiting multiple countries on one trip. However, they typically do not include local phone minutes or SMS, and data allowances are sometimes lower than local tourist packages for a similar price. If Bulgaria is your primary destination and you want local calling capability alongside data, a local operator eSIM or physical SIM is the better choice in 2026.
