Bulgaria SIM Card Cost: Prepaid Plans & Data Prices for Tourists

If you’re arriving in Bulgaria in 2026 and assuming your home carrier’s roaming deal will be good enough, you’re about to pay a lot more than you need to. EU roaming rules help EU passport holders, but visitors from the UK, US, Canada, Australia, and most of the rest of the world are still looking at expensive per-day fees or throttled data caps that make navigation a frustrating experience. A local Bulgarian prepaid SIM costs less than a coffee in most Western European cities and gives you fast 4G or 5G data for your entire trip. This guide breaks down exactly what things cost, which operator to choose, and how the process works — including the eSIM options that have become fully mainstream in 2026.

Why a Local SIM Beats Roaming in Bulgaria

Bulgaria joined the Schengen Area for air and sea travel in 2024, and full land border integration followed in early 2025. This has made entry smoother, but it has done nothing to reduce roaming charges for non-EU visitors. Even for EU travellers, domestic Bulgarian data speeds on local prepaid plans consistently outperform what most European carriers throttle you to under roaming agreements.

The maths are simple. A month of local prepaid data — 20 GB or more — costs between 12 and 20 BGN (roughly 6 to 10 EUR). Most international roaming day-passes cost 3 to 7 EUR per day. For a two-week holiday, a local SIM pays for itself on day two. Beyond the cost, having a local number also makes booking taxis through apps like Bolt, reserving restaurant tables, or calling accommodation hosts far simpler.

Bulgaria’s mobile infrastructure has improved significantly since 2024. The country’s 5G rollout accelerated through 2025, and by 2026 all three major operators — A1, Vivacom, and Yettel — offer 5G in Sofia, Plovdiv, Varna, Burgas, and along major motorway corridors. If your phone supports 5G, a local SIM lets you actually use it.

The Three Operators: A1, Vivacom, and Yettel at a Glance

Bulgaria has three national mobile operators. There are no significant fourth-network MVNOs worth considering for short-term visitors — stick to the main three.

• A1 Bulgaria — www.a1.bg — One of the largest operators in the country. Strong urban coverage and good 4G reliability in mountain resort areas like Bansko and Borovets. The A1 App handles top-ups and bundle activation.
• Vivacom — www.vivacom.bg — Known for competitive data pricing and solid coverage across rural Bulgaria. Often a good choice if you’re travelling through smaller towns or along the Black Sea coast. The My Vivacom app manages your account.
• Yettel — www.yettel.bg — Formerly Telenor, rebranded to Yettel across several European markets. Good network quality and straightforward prepaid options. Managed via the Yettel App.

All three offer English-language support at their larger city stores and have English-accessible versions of their websites and apps. For most tourists, the differences between them are marginal. The best choice is often whichever operator has a store closest to where you land.

Prepaid Tourist SIM Plans and Data Prices

Each operator offers both a dedicated tourist-oriented starter pack and a standard prepaid SIM with separately purchased data bundles. Here is what each looks like in 2026.

A1 Bulgaria Prepaid Plans

A1’s tourist starter pack costs approximately 10–15 BGN (5.11–7.67 EUR) and comes pre-loaded with 10–20 GB of high-speed data, 100–200 local minutes and SMS, and a validity of 15–30 days. If you prefer a basic SIM and add your own bundle, the SIM card itself costs around 6–8 BGN (3.07–4.09 EUR) with a small initial credit. Data bundles can then be purchased separately:

• Small: 5 GB — 7 BGN (3.58 EUR), valid 15 days
• Medium: 15 GB — 12 BGN (6.14 EUR), valid 30 days
• Large: 30 GB — 18 BGN (9.20 EUR), valid 30 days

Bundles are activated through the A1 App, via SMS code, or through the *100# USSD menu.

Vivacom Prepaid Plans

Vivacom tends to offer slightly larger data allowances at similar price points, which makes it attractive for heavy data users. The tourist starter pack runs 10–15 BGN (5.11–7.67 EUR) and includes 10–25 GB of data, 100–250 local minutes and SMS, valid for 15–30 days. The standard SIM costs 5–7 BGN (2.56–3.58 EUR). Separate data bundles:

• Small: 7 GB — 8 BGN (4.09 EUR), valid 15 days
• Medium: 20 GB — 14 BGN (7.16 EUR), valid 30 days
• Large: 40 GB — 20 BGN (10.23 EUR), valid 30 days

Bundles activate via the My Vivacom app, SMS codes, or the *123# USSD menu.

Yettel Bulgaria Prepaid Plans

Yettel’s tourist starter pack sits in the same 10–15 BGN (5.11–7.67 EUR) range, with 10–20 GB of data, 100–200 local minutes and SMS, valid 15–30 days. Standard SIM: 6–8 BGN (3.07–4.09 EUR). Separate data bundles:

• Small: 6 GB — 7 BGN (3.58 EUR), valid 15 days
• Medium: 18 GB — 13 BGN (6.65 EUR), valid 30 days
• Large: 35 GB — 19 BGN (9.71 EUR), valid 30 days

Bundles activate via the Yettel App, SMS codes, or the *123# USSD menu.

2026 Budget Reality: What You’ll Actually Pay

Here is a straightforward cost breakdown by trip length and usage type. All prices in BGN with EUR equivalent.

• Budget (1–2 weeks, light use): Standard SIM (6–8 BGN) + small data bundle (7–8 BGN) = 13–16 BGN total (6.65–8.18 EUR). Covers navigation, messaging, and occasional browsing.
• Mid-range (2–4 weeks, moderate use): Tourist starter pack = 10–15 BGN (5.11–7.67 EUR). Comes ready to go with generous data and local calling. The easiest option for most visitors.
• Comfortable (4 weeks, heavy streaming and remote work): Standard SIM + large 30–40 GB bundle = 23–28 BGN (11.76–14.31 EUR). This gets you enough data to work remotely or stream video without worrying about running out.

Compared to 2024 prices, data bundles in 2026 offer noticeably more gigabytes for similar costs. Market competition between the three operators has pushed prices down and data allowances up over the past two years.

eSIM in Bulgaria: How It Works in 2026

The clearest change since 2024 is that eSIM for prepaid customers is now fully standard across all three Bulgarian operators. In 2024, eSIM was largely restricted to post-paid contracts. In 2026, any tourist can walk into an A1, Vivacom, or Yettel store and leave with a working prepaid eSIM instead of a physical card.

The process is straightforward:

1. Visit an official operator store. Bring your passport.
2. Request a prepaid eSIM and choose your plan.
3. Pay the fee — same price as a physical SIM.
4. Staff will provide a QR code, either printed on paper or displayed on a screen.
5. On your phone, go to Settings → Mobile Data → Add eSIM (exact menu wording varies by phone model and operating system).
6. Scan the QR code. Follow the on-screen prompts.
7. Activation is immediate in most cases.

The main practical advantage for tourists is that you keep your home SIM active in the same phone — useful if you need to receive calls or messages on your regular number while travelling. The main limitation is that eSIM profiles are tied to the device, so if your phone is lost or damaged you cannot simply pop the SIM into a backup phone.

Before you travel, confirm that your phone is eSIM-compatible and that it supports the frequency bands used in Bulgaria (primarily 700 MHz, 1800 MHz, and 2600 MHz for 4G; 3500 MHz for 5G). Most phones sold after 2022 in Europe, the US, and Australia meet these requirements.

Where to Buy Your SIM Card

A1, Vivacom, and Yettel all have kiosks or stores inside the terminal at Sofia International Airport, as well as at Varna and Burgas airports (the two main Black Sea coast gateways). Airport prices are the same as in-city stores, though selection at airport kiosks can be slightly limited compared to full stores.

If your flight arrives late at night and the airport kiosks are closed, most hotels offer WiFi sufficient for messaging until the next morning when you can visit a city store. Official operator stores are found in all major shopping malls, city centre pedestrian areas, and most larger towns across Bulgaria.

What to bring when buying your SIM:

• Your passport — a legal requirement. Driving licences or national ID cards from non-EU countries are not accepted. EU national ID cards may be accepted but a passport is safest.
• Cash or a payment card — most stores accept cards, but having 20–30 BGN in cash as a backup is sensible.
• Your phone — staff can confirm the SIM fits and test signal before you leave.
• If buying an eSIM — your phone must be with you so you can scan the QR code immediately.

Managing Your SIM: Top-Ups, Apps, and USSD Codes

Once your SIM is active, managing it is simple. Each operator has a dedicated app:

• A1 App — available on Google Play and Apple App Store. Check balance, top up credit, activate data bundles.
• My Vivacom — available on Google Play and Apple App Store. Same functions, plus data usage tracking.
• Yettel App — available on Google Play and Apple App Store. Includes bundle management and usage alerts.

If you prefer not to use an app, USSD codes work from any phone without an internet connection:

• A1: Dial *100# to check balance and access the self-service menu.
• Vivacom: Dial *123# for balance and bundle options.
• Yettel: Dial *123# for balance and bundle management.

Physical top-up vouchers are sold at operator stores, petrol stations, supermarkets, and kiosks across the country. Scratch the code on the back and follow the instructions printed on the voucher — usually dialling a short code and entering the voucher number. Self-service terminals in shopping malls also accept cash top-ups without needing to visit a staffed store.

Free WiFi in Bulgaria: What to Expect

Free WiFi at hotels, guesthouses, and Airbnb rentals is essentially universal, though speeds vary widely between a boutique mountain guesthouse and a city hotel. Practically every café also has a password on the chalkboard or printed on the receipt.

Public WiFi in city squares and parks exists in some areas — Sofia’s central pedestrian zones and some metro stations offer it — but it is patchy and unsuitable as a primary data source. For BDZ rail travel, some newer train carriages on longer routes have onboard WiFi by 2026, but connectivity is inconsistent, especially through tunnels and across rural sections of track. Do not rely on train WiFi for navigation, video calls, or anything time-sensitive. A local SIM with a good data bundle will keep you online reliably throughout any train journey.

Common Mistakes Tourists Make

These are the issues that come up repeatedly among visitors who contact us after running into trouble.

• Arriving with a locked phone. If your phone is carrier-locked to your home network, it will not accept a Bulgarian SIM. Check before you travel — contact your carrier and request an unlock code if needed. Most carriers unlock phones for free after 12 months of use.
• Buying a SIM at a kiosk without ID verification. Some street kiosks sell top-up vouchers but cannot legally issue a new SIM. If someone offers you a SIM without asking for your passport, it is not a legitimate transaction.
• Ignoring the validity date. A 30-day bundle bought on day one of a two-week holiday is fine. But if you buy a 15-day bundle on day five, it expires before you leave. Check validity before purchasing.
• Not downloading the operator app before the data runs out. Download the A1 App, My Vivacom, or Yettel App as soon as your SIM is active, while you have data. This way you can top up quickly even if you run out unexpectedly.
• Assuming the airport is the only place to buy. If the airport kiosk has a queue or is closed, city stores in Sofia’s NDK mall, Paradise Center, or the central pedestrian zone on Vitosha Boulevard are easy to reach and less rushed.

Frequently Asked Questions

Do I need my passport to buy a SIM card in Bulgaria?

Yes. Bulgarian law requires a valid passport for the purchase and registration of any prepaid SIM card or eSIM. This applies to all three operators — A1, Vivacom, and Yettel. An EU national ID card may be accepted but bringing your passport avoids any complications. Staff will record your details and the process takes only a few minutes.

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

All three — A1, Vivacom, and Yettel — provide solid 4G coverage in cities, coastal resorts, and ski areas. A1 tends to perform well in mountain regions. Vivacom has strong rural coverage along the Black Sea coast and smaller towns. For most tourist itineraries, the differences are negligible. Choose whichever has a store nearest to your arrival point.

Can I buy a Bulgarian eSIM before I arrive?

As of 2026, Bulgarian prepaid eSIMs from A1, Vivacom, and Yettel still require in-person registration with your passport at an official store. You cannot purchase them remotely in advance. If you want connectivity from the moment you land, buy at the airport store before exiting arrivals. Airport kiosks at Sofia, Varna, and Burgas airports are operational for this purpose.

How much data do I actually need for a two-week holiday in Bulgaria?

For a typical tourist using maps, messaging apps, social media, and occasional video streaming, 10–15 GB is comfortable for two weeks. Light users can get by on 5–7 GB. If you plan to work remotely, stream video daily, or use your phone as a hotspot for a laptop, choose a 20–30 GB bundle. Vivacom’s 20 GB plan at 14 BGN (7.16 EUR) is good value for this usage level.

Will my data bundle work across all of Bulgaria, including remote areas?

4G coverage is reliable in all cities, major towns, coastal resorts, ski resorts, and along main motorways. In very remote mountain areas — deep valleys, minor hiking trails far from settlements — signal can be weak or absent regardless of operator. For hiking in the Rila or Pirin mountains, download offline maps via Google Maps or Maps.me before you head out. Do not depend on live data in genuinely remote terrain.
