Where to Buy a Bulgaria SIM Card: Airports, Stores & Online Options

Bulgaria joined Schengen in 2024, and cross-border travel has become smoother than ever — but staying Connected inside the country still trips up a surprising number of visitors in 2026. The problem is rarely coverage (Bulgaria’s networks are solid) or price (plans are genuinely cheap by European standards). The problem is arriving without a plan: landing in Varna, assuming the airport will have a kiosk, and finding nothing open at 11 p.m. This guide covers every realistic way to get a Bulgarian SIM card — airport kiosks, city stores, supermarkets, and eSIM — so you are connected before you leave arrivals.

Three Operators, One Country — Understanding Bulgaria’s Mobile Market

Bulgaria’s mobile market is shared between three main operators: A1 Bulgaria, Vivacom, and Yettel Bulgaria (rebranded from Telenor a few years back). All three run nationwide 4G networks, and all three are actively expanding 5G coverage in urban areas as of 2026. For a tourist on a short trip, the differences between them are minor. Coverage in Sofia, Plovdiv, Varna, and Burgas is excellent across all three. In rural mountain areas or along smaller roads, coverage can vary — Vivacom and A1 tend to edge out Yettel slightly in remote Rhodope and Rila territory, though this gap is narrowing.

Each operator offers prepaid starter packs that require no Bulgarian address or contract. You just need a valid passport — or an EU/EEA national ID card if you have one. Bulgarian law requires every SIM to be registered to an identity document. This is not optional and not something you can skip by buying from a gas station shelf. Registration happens at the point of sale, and you will be asked to show ID every single time, regardless of where you buy.

The operator apps — My A1, My Vivacom, and the Yettel App — are all available on the Google Play Store and Apple App Store. Once you have a SIM, these apps let you check your remaining data, top up with a card, and manage your plan. Download the app before you leave the store, while a staff member can still help you log in.

Buying a SIM Card at Bulgarian Airports

For most visitors flying into Bulgaria, Sofia Airport (SOF) is the entry point, and Terminal 2 is the best place in the country to buy a SIM. All three operators — A1, Vivacom, and Yettel — have small kiosks or dedicated counters in the Terminal 2 arrivals area. Staff generally speak English, the process takes 5–10 minutes if there is no queue, and prices are identical to city-centre stores. There is no airport surcharge.

Kiosks at Terminal 2 are typically open from around 08:00 to between 20:00 and 22:00. If your flight lands late at night, do not count on finding one open. In that case, use the airport WiFi to arrange your first night’s accommodation, and head to a city store or shopping mall the following morning.

The situation at Varna Airport (VAR) and Burgas Airport (BOJ) is less predictable. There may be a small multi-brand electronics kiosk selling starter packs for one or two operators, but consistent operator presence cannot be guaranteed. If you are flying into Varna or Burgas — particularly during the summer charter season — assume you will need to buy your SIM in the city centre. Both Varna and Burgas have central pedestrian streets lined with official operator stores within a short taxi or bus ride from the airport.

Official Operator Stores — The Most Reliable Option

Regardless of where you arrive, official operator stores in city centres are the gold standard for buying a prepaid SIM in Bulgaria. A1, Vivacom, and Yettel all have branches inside major shopping malls — in Sofia, look at Paradise Center, Serdika Center, and Mall of Sofia. There are also standalone street-level stores on and near main high streets in every significant town.

To find the nearest branch, use the store locators on the operator websites:

• A1: www.a1.bg
• Vivacom: www.vivacom.bg
• Yettel: www.yettel.bg

Standard operating hours run Monday to Friday, roughly 09:00 or 10:00 to 18:00 or 19:00. Saturday hours are typically shorter — around 10:00 to 17:00. Most standalone stores are closed Sundays and public holidays. Shopping mall branches tend to follow mall hours and are often open seven days a week, which makes them the practical choice if you arrive over a weekend.

The in-store process is straightforward. Take a queue ticket if the system is in use, tell the assistant you want a prepaid SIM for a tourist, hand over your passport, and they handle the rest — registration form, SIM insertion, activation. Before you leave, ask them to confirm you can load a page in a browser and make a test call. The whole thing takes 5–15 minutes.

Supermarkets, Electronics Stores & Gas Stations — What You Need to Know

You will spot prepaid starter pack boxes at Billa, Kaufland, Fantastico, and Lidl supermarkets, as well as at electronics chains like Technopolis and Technomarket, and at fuel stations including OMV, Shell, and Lukoil. These SIM cards are real — but there is a catch.

Buying from a shelf means the SIM is not registered to your name yet. Bulgarian law requires that registration step before the SIM can be activated for use. That usually means you still need to visit an official operator store with your passport to complete registration — or go through an online registration process that is currently only available in Bulgarian, which is a genuine obstacle for most tourists.

The bottom line: supermarket SIM cards are fine for Bulgarian residents who can handle online registration or who are near a store. For a tourist who wants to be online within the hour, they create unnecessary friction. Stick to airport kiosks or official stores for your first SIM purchase.

Top-up vouchers sold at supermarkets and gas stations are a different story — these work perfectly once your SIM is already active and registered. You will find them in denominations of 10 BGN, 20 BGN, and higher, near the checkout or behind the counter.

eSIM and Online Options for Bulgaria in 2026

The eSIM picture for Bulgaria has changed since 2024, though it is still not as seamless as in some Western European markets. As of 2026, direct eSIM purchase for prepaid tourist plans from A1, Vivacom, or Yettel is not yet fully standardised for foreign visitors. All three operators are expected to expand dedicated tourist eSIM offerings, but availability varies and is worth checking directly on their websites before you travel.

The more reliable route right now is a third-party eSIM provider. Services like Airalo, Holafly, Nomad, and MobiMatter all offer eSIMs covering Bulgaria. These are data-only plans — no local Bulgarian phone number, no SMS bundle — but for most travellers who rely on WhatsApp, Google Maps, and browser browsing, that is perfectly adequate.

For reference, Airalo’s Bulgaria eSIM pricing runs roughly 4.50 USD for 1 GB over 7 days, and around 15 USD for 5 GB over 30 days. You purchase online, receive a QR code by email, and scan it in your phone’s SIM settings before or after arrival. Your device must support eSIM — most flagship smartphones sold from 2022 onward do, but budget Android models vary.

The advantage of third-party eSIMs is convenience: no passport needed, no queuing, no language barrier. The disadvantage is cost per gigabyte compared to local prepaid plans, and the absence of voice calls. If you need a local Bulgarian number — to book restaurants, call accommodation, or reach local services — a physical SIM from an operator store is the better choice.

2026 Prepaid Plan Prices and What You Actually Get

The prices below reflect estimated 2026 figures based on late-2024 offerings, adjusted for the anticipated 5–10% inflationary increase. All BGN prices use the fixed rate of 1 EUR = 1.95583 BGN.

Budget Tier

A basic top-up of 10 BGN (approx. 5.10 EUR) typically unlocks a short-term bundle: around 5–6 GB of data plus unlimited national calls, valid for 14–15 days. This is the right level for a week-long trip where you mostly use hotel WiFi and just need mobile data for navigation and messaging.

Mid-Range Tier (Most Popular for Tourists)

• A1 Start-style pack: 15–20 BGN (approx. 7.65–10.20 EUR) — 10 GB data, unlimited national calls, up to 200 minutes to selected EU numbers, valid 30 days.
• Vivacom Start-style pack: 18–22 BGN (approx. 9.18–11.22 EUR) — 12 GB data, unlimited national calls, 100 national SMS, valid 28–30 days.
• Yettel Prepaid-style pack: 17–21 BGN (approx. 8.67–10.71 EUR) — 15 GB data, unlimited national calls, 100 national SMS, valid 30 days.

Comfortable Tier

Higher top-up vouchers of 30–50 BGN (approx. 15.30–25.50 EUR) unlock larger data packages or roaming-inclusive bundles. These are worth considering if you are travelling for more than three weeks or splitting your time between Bulgaria and neighbouring countries.

All plans can be topped up via the operator’s app using a standard credit or debit card, which means you are never stuck if your initial bundle runs out mid-trip.

Step-by-Step: Getting Connected the Moment You Land

1. Before you fly: Check your phone’s compatibility. If you have a dual-SIM or eSIM-capable device, decide whether a third-party eSIM or a local physical SIM suits your needs better. Download the relevant operator app if you have already chosen a provider.
2. At Sofia Terminal 2 arrivals: Look for the A1, Vivacom, or Yettel kiosk signs as you exit the baggage hall. All three are in the same general area. Opening hours run approximately 08:00–22:00.
3. Present your passport to the sales assistant. EU/EEA nationals can use a national ID card.
4. Choose a plan. Tell the assistant how many days you are staying and roughly how much data you use per day. They will recommend the appropriate starter pack.
5. Pay in cash (BGN) or by card. Both are universally accepted. Card payments via contactless work at all three operator kiosks and stores.
6. Let the assistant activate the SIM and ideally insert it into your phone. Activation typically takes a few minutes, occasionally up to an hour for full data service to initialise.
7. Test before you leave. Open a browser, load any page, and make a brief test call if your plan includes voice. Leave the store only when you are confident it is working.
8. Save the top-up method. Add the operator’s app to your home screen. If your data runs out, a top-up through the app takes under two minutes.

Free WiFi in Bulgaria — When You Can Skip the SIM

If you are on a very short trip — two or three days in Sofia, staying in one hotel — it is technically possible to manage on WiFi alone. Hotels, cafés, and restaurants across Bulgaria almost universally offer free WiFi. Large shopping malls provide free public WiFi, and some city centres, including parts of Sofia and Plovdiv, have free municipal hotspots around central squares and pedestrian zones, though reliability is inconsistent. A handful of newer BDZ intercity trains carry free WiFi, but coverage is patchy and dependent on which rolling stock is rostered for your route on a given day.

The honest assessment: public WiFi is a supplement, not a substitute. The moment you leave a café or hotel lobby, you are without data — which means no maps, no translation, no ride-hailing. For any trip longer than 48 hours or any itinerary that takes you outside a single city, a local SIM card is the right call.

Common Mistakes Tourists Make When Buying a Bulgarian SIM

Assuming Varna or Burgas airport will have a kiosk. It might, but it might not. If your flight arrives after dark or during a low-season schedule, you could find nothing open. Plan to buy in the city.

Buying a SIM from a supermarket shelf and expecting immediate use. Without completing ID registration at an official store, the SIM will not activate fully. Do not waste time trying to self-register in Bulgarian on a slow airport WiFi connection.

Forgetting to bring a passport. An EU national ID card works, but a driving licence does not. If your passport is in your checked luggage, retrieve it before heading to a kiosk.

Relying on a roaming plan from your home country without checking Bulgaria’s rates. Bulgaria has been inside the Schengen Area since 2024, but Schengen membership does not automatically mean cheap roaming — that depends on your home operator and EU roaming regulations. Check your plan before you travel. A Bulgarian prepaid SIM will almost always be cheaper for data-heavy use.

Skipping the in-store test. Always confirm the SIM is working before you walk out. Staff are helpful, and a non-working SIM is easy to fix on the spot — and much harder to sort out from a mountain village two days later.

Frequently Asked Questions

Do I need a Bulgarian address to buy a prepaid SIM card in Bulgaria?

No. A valid passport or EU/EEA national ID card is all you need. The operator registers the SIM to your identity document, not to a local address. Foreign tourists buy prepaid SIMs in Bulgaria every day without any residential registration. The process is routine and takes under 15 minutes at an official store.

Which Bulgarian mobile operator has the best coverage for tourists in 2026?

In major cities and along main highways, A1, Vivacom, and Yettel are all reliable. For rural areas, mountain hiking routes, or the Rhodope and Rila regions, A1 and Vivacom tend to edge ahead slightly. If rural coverage matters for your trip, ask the store assistant specifically about the area you plan to visit.

Can I use a Bulgarian prepaid SIM card in other Balkan countries?

Yes, but roaming charges apply outside Bulgaria. EU roaming rules cover EU member states, meaning your Bulgarian data bundle works in Greece, Romania, and other EU countries at no extra cost. For non-EU neighbours like North Macedonia or Serbia, standard international roaming rates apply and can be expensive. Check roaming rates on the operator’s website before crossing any non-EU border.

Are third-party eSIMs like Airalo reliable for use in Bulgaria?

Yes, for data use they are reliable. Third-party eSIMs run on local network infrastructure via roaming agreements, so you will have good coverage in cities and major tourist areas. The main limitations are that they are data-only — no Bulgarian phone number, no SMS — and the cost per gigabyte is higher than buying a local prepaid SIM from A1, Vivacom, or Yettel directly.

How do I top up my Bulgarian prepaid SIM if my data runs out mid-trip?

The fastest method is through the operator’s app — My A1, My Vivacom, or the Yettel App — using a standard credit or debit card. You can also top up at any EasyPay terminal (found in post offices and many convenience stores), at the operator’s own stores, or by buying a top-up voucher at a supermarket or gas station and entering the code via the app or a short dial code.
