Fiber Internet in Phuket: Where It's Available in 2026

I've worked from home in Phuket for the better part of seven years, and nothing tests your patience quite like finding out your beautiful villa in Rawai is 300 metres outside the fiber coverage zone. The salesperson will cheerfully tell you it's "coming soon." That was in 2021. Still coming.

This guide cuts through the marketing and tells you exactly which areas of Phuket have real fiber connectivity, which ISPs are worth using, and what to check before you sign a lease or a two-year contract.

Phuket's Internet Infrastructure: The Honest Picture

Phuket punches above its weight for internet infrastructure compared to most of Thailand — it's a major tourist destination with high demand from hotels, coworking spaces, and the growing expat community. But it's still an island, and the fiber rollout is uneven.

The main distinction is between fiber-to-the-building (FTTB) and fiber-to-the-home (FTTH). Most urban and semi-urban areas in Phuket now have fiber reaching the building or street cabinet; true FTTH to individual units is common in newer condos and housing developments but still patchy in older or more rural properties.

The Four Major ISPs in Phuket

One important note: NT (formerly CAT Telecom) merged with TOT to form National Telecom. The service is functional but generally slower to expand coverage than the private ISPs. If you're in a peri-urban area, AIS or True Online are your best bets.

Fiber Coverage by Area: What I Know From Living Here

Phuket Town — Best Coverage

Phuket Town has the densest fiber infrastructure on the island. AIS, True, 3BB, and NT all operate here. You can realistically get 200–500Mbps on a ฿799–฿999/month plan. The old Sino-Portuguese shophouse district and newer residential developments around Koh Kaew all have strong coverage. If you're based here, the internet should be the least of your concerns.

Bang Tao & Laguna — Good Coverage

The Laguna resort complex has its own internal network infrastructure, and the broader Bang Tao area has strong AIS and True Online coverage. Most modern condos and villas here come pre-wired. Properties inside Laguna itself often use a managed service — check with the juristic office. Outside the complex, Bang Tao's west coast areas are generally well-covered.

Patong — Good But Congested

Patong has excellent fiber infrastructure, but the sheer number of connections — hotels, bars, short-term rentals — can cause congestion during peak season (November–February). True Online dominates here. If you're working remotely, Patong is probably not your first choice anyway — it's loud, traffic-choked, and the bars start at noon. But if you're there, the fiber itself is fine.

Kata & Karon — Decent Coverage

Kata and Karon are well-served by True Online. Properties close to the main beach road are solid; anything up in the hills or along quieter sois becomes less reliable. Always check the specific address before committing.

Chalong & Rawai — Mixed

Chalong centre has reasonably good fiber thanks to proximity to Phuket Town. Rawai is trickier — some streets have full FTTH, others are still on copper ADSL or relying on 4G. The Sai Yuan Road area and properties close to Nai Harn lake have improved significantly since 2023, but pockets of poor connectivity remain. Always verify the specific address with AIS or True before you sign anything.

Nai Harn — Patchy

Nai Harn is one of the most beautiful places to live in Phuket, but the internet infrastructure hasn't kept up with its popularity. Close to the beach and the main road, you're generally fine. Back roads and hillside properties are another matter. Many Nai Harn remote workers run a True Online fiber line where available and a 5G AIS SIM as backup. It works, but it's more effort than Phuket Town.

Kamala & Surin — Good in Centre, Patchy on Hills

Kamala village centre and the Surin beach area have good coverage. Hillside properties above Kamala — the kind with incredible sea views that look amazing on Instagram — are often beyond the fiber reach. The ISPs have been extending coverage into these areas, but it's slow progress. If the view is worth it to you, budget for a 5G home router as your primary connection.

AIS Fibre vs True Online: Which Should You Choose?

This is the question every expat asks, and the honest answer is: it depends on your area. But here's my general experience after years of both:

AIS Fibre

AIS tends to have better coverage in residential areas away from the tourist strip. Their app (myAIS) is in English and relatively straightforward. Customer service has English-speaking staff on the 1175 hotline. The main downside: AIS can be slower to fix outages in remote areas — if something goes wrong at 11pm on a public holiday, you might be waiting until the next business day.

True Online

True dominates in tourist-heavy areas and has arguably the most aggressive pricing for new customers (regular 50–100% speed promotions). Their app is less user-friendly in English, but the coverage in Kata, Karon, and Patong is hard to beat. If your area has both, True often quotes the cheapest 12-month promotional rate.

3BB

3BB (now partly merged with NT's retail operations) is worth checking in Phuket Town suburbs and Kathu. Pricing is competitive and service is generally solid, though less known among expats. Worth a quote if you're in a well-covered area.

4G/5G as a Home Internet Alternative

Don't overlook mobile internet as a primary or backup connection. Phuket has excellent 5G coverage in most built-up areas, and a dedicated 4G/5G home router from AIS or DTAC can deliver 50–200Mbps with no installation hassle and no contract.

The throttling kicks in when you've used your high-speed allocation (typically 50–100GB), dropping to 1–5Mbps. Fine for email and messaging; not fine for video calls. For serious remote work, fiber remains preferable — but 5G home wireless is a solid stopgap while you wait for a fiber installation or for areas where fiber simply isn't available.

Getting Your Line Installed: Step by Step

The installation process is simpler than you might expect, but there are a few things to watch for.

1. Check coverage at your specific address — use the ISP website or, better, call or WhatsApp customer service with your exact address
2. Choose your package — for most remote workers, a 100–300Mbps plan at ฿799–฿999/month is the sweet spot
3. Documents needed: passport copy, Thai SIM number (for account setup), and a copy of your lease agreement as proof of address
4. Schedule installation — typically 3–7 business days after contract signing; engineers are generally prompt in Phuket
5. Installation day: someone needs to be home; the process takes 1–3 hours depending on how the building is cabled
6. Router: the ISP will provide a router (usually a dual-band unit); you can add your own mesh system if you need wider coverage in a larger property

Internet Included in Rent: What to Watch For

Many landlords advertise "internet included" — this usually means a shared VDSL or cable line from the building's juristic office, divided among multiple units. The reality is often 20–50Mbps shared between 10–30 units. Fine for casual browsing; not ideal if you're on Zoom calls all day.

If internet quality matters to you, ask specifically: "Is it fiber to the unit?" and "What is the guaranteed speed for my unit?" Get it in writing. If the answer is vague, assume it's a shared connection and budget for your own dedicated line.

Practical Tips for Remote Workers

• Always have a backup SIM: Keep an AIS or DTAC data SIM in your phone or laptop. When the fiber goes down during a monsoon storm, you'll be glad you did.
• Use a UPS: A small uninterruptible power supply (฿800–฿2,500 at HomePro or PowerMall in Phuket Town) keeps your router alive during brief power blips — common in Phuket's wet season.
• Mesh networking: If your villa is large or has thick walls, a TP-Link Deco or similar mesh system (฿2,500–฿6,000 at Jaymart or PowerMall) will eliminate dead spots.
• VPN for streaming: If you need access to geo-locked content from home, a VPN is useful. Our VPN guide for Phuket covers the best options tested from Thai ISPs.
