Best & Fastest Internet Speed Providers in Croatia (2025)

Looking for the fastest, most reliable internet in Croatia in 2025? This guide compares Hrvatski Telekom (HT), A1, Telemach, Iskon and other top providers — speeds, plans, and typical prices so you can pick the right home or mobile connection.

Croatia’s internet landscape in 2025 is shaped by rapid fiber rollout, stronger competition from regional operators, and attractive mobile eSIM/tourist packages that make staying connected easier than ever. Whether you need gigabit fiber for streaming and gaming, a stable home office connection, or a cheap high-data mobile option while visiting, this guide breaks down the best and fastest providers, typical speeds, and price ranges so you can choose with confidence.

What “fastest” means in Croatia right now

When we say “fastest,” we mean both top advertised download/upload speeds and real-world stability (latency, packet loss). In Croatia today, gigabit (1 Gbit/s and above) fixed-line services are widely available in major cities and expanding into regional centers. At the same time, mobile networks provide excellent 4G/5G coverage for on-the-go connectivity. Overall market tests and coverage studies in 2025 show a clear tier of leading providers who combine speed, coverage and consistent performance.

1) Hrvatski Telekom (HT) — Best national fiber coverage & top reliability

Why choose HT: Hrvatski Telekom (HT) owns the broadest FTTH/FTTB footprint in Croatia and is the name most associated with reliable, nationwide fiber rollout. If availability is your main concern (especially outside Zagreb and major coastal towns), HT is frequently the default option because of its long-term infrastructure investments and consistent performance. HT markets FTTH packages up to 1 Gbit/s for residential customers and continues to expand fiber into more regions.

Typical plans & prices (what to expect):

• Up to 250–500 Mbit/s: mid-range home packages — competitive prices for families.

• 1 Gbit/s (FTTH): top tier plan for heavy users (streaming, uploads, cloud backups).

• Price range: HT’s pricing varies by promotion and region (often with contract discounts or bundle savings). Expect household gigabit plans to be priced in the middle-to-higher segment compared to challengers because you’re paying for broad availability and a premium network.

Who it’s best for: households that need top reliability across Croatia, remote workers who value stable uploads, and users who want the widest fiber availability.

2) A1 Hrvatska — Best for raw speeds & promotional value

Why choose A1: A1 has aggressively pushed faster fixed packages — including multi-gigabit tiers — and frequently runs promotional pricing for new customers. Their fixed internet lineup includes “Mega NET” and “Giga NET” options with speeds that reach well into the gigabit category; their marketing emphasizes speeds “up to 2 Gbit/s” on supported infrastructure. A1 is also competitive on bundled offers (internet + TV + mobile).

Typical plans & prices (what to expect):

• Introductory offers: A1 commonly offers strong discounts for the first 12 months (example: promotional monthly price around €12.70/month for certain packages during the first year, with regular price rising to the mid-20s €/month after the promotion). Exact packages and availability depend on address and infrastructure.

• Top speeds: up to 1–2 Gbit/s where cable or fiber supports it.

Who it’s best for: speed seekers who can take advantage of promotional pricing, gamers needing low latency, and families that want high bandwidth for many simultaneous streams.

3) Telemach — Aggressive regional challenger with flexible bundles

Why choose Telemach: Telemach (part of the United Group) has rapidly expanded in the region with modern cable and fiber offerings and a customer-friendly product lineup. They are particularly competitive for combined TV + internet bundles and for users who want flexible contract options. Telemach also markets simple tourist/mobile packages that are very wallet-friendly.

Typical plans & prices (what to expect):

• Home fiber/cable: competitive mid-to-high speeds with bundle discounts.

• Mobile/tourist packages: Telemach advertises simple prepaid/tourist options (including short unlimited data packages for visitors) at very low one-time prices.

Who it’s best for: people in urban areas where Telemach has built cable/fiber presence, customers who want good value bundles, and short-term visitors seeking low-cost mobile data.

4) Iskon — Great value for urban fiber customers (part of HT group)

Why choose Iskon: Iskon operates as a consumer-focused brand with attractive pricing and simple plans aimed at urban users. It’s a long-standing Croatian ISP now under the Deutsche Telekom family (HT group), so it often benefits from HT’s infrastructure while keeping a value-oriented product line. Iskon is frequently recommended by locals as a solid, affordable fiber option.

Typical plans & prices (what to expect):

• Common offering: economical 300/150 Mbit/s and 500/500 Mbit/s fiber plans priced noticeably lower than some leading brands.

• Price range: in many locations users report paying into the low-to-mid-€20s or even under €20 for mid-range fiber deals when promotions are available.

Who it’s best for: renters and urban households who want a good price/performance ratio and local customer service.

5) Regional and niche ISPs (Metronet, Magic Net and smaller fiber specialists)

Why consider them: In many Croatian towns, local fiber specialists and municipal projects offer very competitive prices and excellent speeds because they operate on a smaller scale and target specific neighborhoods. These providers can be the cheapest route to fiber where they exist, often beating national players on price for the same speeds.

Who it’s best for: users in marketable areas where a local provider has fiber already — always check availability maps before committing.

Mobile internet & tourist eSIMs — fast, cheap, and convenient

If you’re a visitor, digital nomad, or need a secondary connection, Croatian mobile providers now offer excellent short-term eSIM and prepaid packages. A1 and HT both offer 10-day unlimited 5G eSIM/tourist options at low prices (A1’s 10-day unlimited eSIM for about €7.90 and HT tourist unlimited packages commonly around €10–€12 for 10 days), making temporary high-speed access very affordable. These packages are ideal for streaming, maps and video calls while traveling.

How prices compare in 2025 

• Entry mobile data (monthly): typical prepaid plans from €10–€25 depending on data bundle.

• Home fiber (mid-range, promotional): many A1/Iskon/Telemach packages run introductory offers around €12–€20/month for the first year, rising to €20–€35/month afterward depending on speed and bundle.

• Home gigabit: expect to pay a premium for 1 Gbit/s in areas where it’s widely available; price commonly in the €25–€45/month band depending on vendor discounts, equipment rental and bundled services.

⚠️ Note: Prices and promotions change frequently. Always check the provider’s availability checker and current web-only deals before ordering.

Choosing the right provider: decision checklist

1. Check fiber availability at your address — the fastest plans require FTTH/FTTB. (Use each provider’s “provjeri dostupnost / check availability” tools.) 

2. Decide if upload speed matters — creators, streamers and remote workers need symmetric or high upload.

3. Bundle vs standalone: bundling mobile + TV often reduces monthly cost but locks you into a contract.

4. Introductory price traps: promotional rates often last 12–24 months; note the renewal price.

5. Customer service & local support: smaller ISPs can have better local service; national operators offer broader coverage.

Tips to save money without losing speed

• Take advantage of web promotions — many providers reserve the best prices for online signups.

• Negotiate on contract renewal — if switching is costly, ask customer care for retention discounts.

• Check for bundle discounts — combining TV + mobile + internet can be cheaper.

• Use mobile eSIMs for short stays — tourists can get unlimited 10-day packages for under €12.

Recommendation — who should pick whom?

• If you want the widest fiber coverage and rock-solid reliability: choose Hrvatski Telekom (HT).

• If you want the fastest promotional prices and multi-gig options where available: choose A1.

• If you want value urban fiber and friendly local pricing: consider Iskon.

• If you’re on the move or visiting: pick a mobile eSIM/tourist plan from A1, HT or Telemach for cheap, fast access.
