Best & Fastest Internet Providers in Bulgaria (2025) 

Looking for the fastest and most reliable home internet in Bulgaria in 2025? This guide compares A1, Vivacom, Yettel and top regional fiber providers, lists typical speeds and realistic monthly prices (BGN), and shows which provider is best for gaming, streaming, or tight budgets.

Bulgaria’s internet market in 2025 offers solid competition: national operators A1, Vivacom and Yettel continue to invest in fibre and 5G home solutions, while regional fibre players bring aggressive gigabit offers in cities. Choosing the best provider depends on three things: the actual available speed at your address, the price after promotions, and service reliability. Below is a practical, SEO-optimized guide to the fastest providers, typical speeds you can expect, and representative prices to help you choose in 2025.

The top contenders (at a glance)

• A1 Bulgaria — strong national fibre and fixed broadband footprint; consistently high mobile data speeds.

• Vivacom — broad fibre plans and regular promotional discounts on fibre + TV bundles.

• Yettel — mobile-first operator with competitive 5G home & fixed wireless packages and budget-friendly prepaid options.

• Regional fibre providers (e.g., Cooolbox and local ISPs) — often the best price-per-Gbps, especially in cities like Plovdiv or Veliko Tarnovo.

How we judge “best” and “fastest”

To be useful for SEO readers, we consider:

1. Peak advertised speeds (what the provider sells).

2. Real-world performance reports (independent network tests).

3. Price per month and promotional pricing (what you likely pay in the first contract months).

4. Coverage — national vs regional availability.

A1 Bulgaria — the all-rounder for speed & coverage

A1 remains one of Bulgaria’s leading providers for both fixed fibre and mobile data. Their home internet product line focuses on fibre offers that include free or discounted Wi-Fi equipment and easy online ordering. A1 frequently positions mid-tier plans (e.g., 75 Mbps class historically) as low-cost entry routes while also offering higher-tier fibre plans where fibre is available. If you prioritise a national operator with predictable support and consistent mobile speed performance, A1 is a safe choice.

Representative prices (what to expect in 2025):

• Entry fibre plan (up to ~75 Mbps): historically seen around BGN 10–15/month promotional rates for the first months.

• Mid / high fibre (200–1000 Mbps): expect BGN 20–60/month depending on the city and bundle choices (TV, fixed voice). Exact offers vary by region.

Best for: customers who want consistent nationwide coverage, bundled TV + internet, and a reputable support network.

Vivacom — aggressive fibre promotions & TV bundles

Vivacom continues to push fibre plans bundled with EON TV and often runs promotions such as “50% off fibre for up to 9 months” and included Wi-Fi 6 routers on certain offers. Vivacom’s fibre packages include a range from basic (100–200 Mbps) up to higher-tier fibre packages where infrastructure exists. There were price adjustments announced in early 2025, so watch for the latest local price changes when you sign up.

Representative prices (2025 snapshots):

• Promotional 200 Mbps bundle (first months): can be advertised at BGN ~16–25/month in certain promotional combos. After promo, normal tariff increases may apply.

• Higher-tier symmetric fibre (300–1000 Mbps): BGN 30–70/month depending on extras and contract length.

Best for: users who want bundled TV + internet and who can take advantage of time-limited promotional pricing.

Yettel — 5G home and budget-friendly plans

Yettel (the rebrand of operators formerly known as Telenor in some markets) focuses on mobile and 5G Home Internet packages alongside prepaid and fixed offerings. Yettel’s home internet packages often include an initial lower subscription for the first 3 months on promotional listings (e.g., single-digit BGN prices for early months), moving to regular tariffs after the promo period. Their competitive short-term pricing and wide mobile coverage make them a strong competitor in places where 5G or fixed wireless is adequate.

Representative prices:

• 5G / Home Internet basic (up to 50–100 Mbps typical in FWA): promotional BGN 8.99–11.99/month for first months, then higher standard prices after promo.

Best for: renters, short-term customers, or households in areas where fibre is not yet available but 5G coverage is strong.

Regional fibre ISPs — unbeatable gigabit value

Many cities in Bulgaria are served by regional fibre providers (local wholesale or municipal networks) that offer true 1 Gbps for a fraction of the price charged by national operators. One frequently-cited example is Cooolbox, which has offered 1 Gbps plans around BGN 27.90/month in areas where it operates — a standout price-per-gigabit compared with national operators. Regional players are often the best value if they cover your building.

Representative prices:

• 1 Gbps (regional fibre): BGN ~20–35/month typical promotional/regular ranges depending on provider and city. Installation and router offers are often included.

Best for: heavy streamers, gamers, small offices, and anyone who wants the most bandwidth for the money — only if the provider serves your apartment/area.

Mobile internet reality check — actual performance vs advertised

Mobile network experience tests (e.g., independent measurement reports) show that A1, Vivacom and Yettel trade places across different performance metrics (download speed, 5G performance, latency). Independent testing in early 2025 highlighted A1 as having some of the fastest mobile download and 5G peak speeds, while Vivacom and Yettel also score well on coverage and reliability in many regions. If you plan to rely on mobile or 5G home internet, check the latest coverage maps and independent measurements for your city.

Which provider is best for you? A short decision guide

• Best for maximum pure speed (where available): regional fibre (Cooolbox / other local ISPs) — 1 Gbps at low monthly rates.

• Best overall national coverage and consistent performance: A1 (fibre + mobile).

• Best promotional bundles (TV + internet): Vivacom — aggressive discounts on fibre + EON TV.

• Best when fibre is not available / cheap short-term option: Yettel’s 5G Home and prepaid internet packages.

Tips to get the lowest real price in 2025

1. Check local regional ISPs first. If Cooolbox or a municipal fibre provider serves your building, you may get the cheapest gigabit plan.

2. Watch promo periods (first 3–9 months). National operators frequently advertise steep discounts for the first months; read terms for the post-promo price.

3. Bundle only if you’ll use it. Bundles can lower monthly bills but lock you into TV/voice services you may not need.

4. Test speed after install. Use an independent speed test during peak hours — real-world performance matters more than advertised peak numbers.                                                                                                            Representative price comparison (summary table)

Note: these are typical examples and promotional snapshots you may see in 2025 — actual prices and promos vary by city, availability, and date.

• A1 — Entry fibre: BGN ~10–15/month (promo); Mid/high fibre: BGN 20–60/month.

• Vivacom — Promotional fibre + TV (200 Mbps): BGN ~16–25/month for promo months; post-promo higher.

• Yettel — Home Internet 50/100/200 (promo): BGN 8.99–15.49/month first months (example promo table).

• Cooolbox (regional) — 1 Gbps: BGN 27.90/month (example city offer).

Recommendation

1. Start by checking local availability. Enter your address on provider coverage pages (A1, Vivacom, Yettel) and look for regional fibre options. National operators may not match regional fibre pricing where those networks exist.

2. Compare total contract cost (promo months + standard tariff + installation fees). Promo prices are attractive but always verify the long-term rate.

3. If you need the fastest possible connection for gaming/streaming, prioritise regional fibre or a confirmed gigabit fibre plan where available.
