Connectivity & Internet in Phuket

Good to Know

• Phuket's fiber broadband covers most urban and tourist areas with speeds among the fastest in Southeast Asia; real-world speeds average 80–200 Mbps on mid-tier plans.
• 4G coverage is near-ubiquitous in Phuket; 5G is widespread with AIS leading at ~136 Mbps average. Both networks provide reliable connectivity suitable for video calls, streaming, and remote work.
• Tourist SIM cards are affordable (starting ฿299–399) and readily available at the airport and throughout Phuket. AIS is fastest; True Move H offers good value for unlimited data; DTAC is cheapest in some scenarios.
• Installation of home broadband typically takes 3–7 days. AIS Fibre and True Online are the most popular providers for expats. Verify street-level availability before committing to a long-term contract.
• Thick concrete walls in Thai properties can block WiFi; consider mesh systems from providers like AIS-3BB or upgrade to a quality router. Some expats use dual internet connections (fiber + 4G router) for business-grade reliability.
• If renting a villa or condo without your own fiber line, you can supplement with a 4G/5G mobile router (฿299–699/month unlimited) for stable speeds of 50–150 Mbps.
• Public WiFi is available in hotels, cafes, and some areas (e.g., Patong); speeds vary. Reliable local SIM data is a better bet for consistent connectivity.
• Islands outside Phuket (Phi Phi, Koh Racha) have weaker 3G-only coverage; plan important video meetings from Phuket Town or tourist beaches.
• Peak evening hours can cause temporary congestion on mobile networks. For critical tasks, fiber-optic home broadband is more reliable than mobile data.
• Contract terms: Most fiber providers require 12–24 month commitments. Month-to-month options exist at slightly higher rates. Installation fees (฿1000–3000) are often waived during promotions.
• e-SIM is supported by AIS, True, and DTAC for tourists and digital nomads. It must be purchased online in advance; cannot be activated at the airport.
