Southeast Asia is the original digital nomad territory — Chiang Mai, Bali, and Ho Chi Minh City have been nomad hubs for over a decade. The region offers compelling economics: low cost of living, warm weather, great food, and increasingly good internet infrastructure. But internet quality varies enormously between countries, between cities, and between urban and rural areas.
Key Takeaways
- Thailand offers the best value data plans in Southeast Asia — under 2 euros per day
- Bali (Indonesia) has strong 4G in South Bali and Ubud — reliable for remote work
- Vietnam has good urban coverage but requires local registration for SIM cards
- Malaysia (KL) has excellent infrastructure — one of the best in the region
- ConnectPls covers all major Southeast Asian destinations with eSIM and SIM subscriptions
Thailand: The Nomad’s Data Paradise
Thailand consistently offers the cheapest and most reliable mobile data for nomads in Southeast Asia. AIS, DTAC (merged with True Move), and True Move all offer excellent 4G coverage throughout Bangkok, Chiang Mai, Phuket, and Koh Samui. Data plans are extraordinarily cheap: unlimited data for 30 days costs approximately 8-14 euros. Speed is genuinely good — 20-50Mbps is typical on 4G in urban areas. Chiang Mai specifically has become a nomad infrastructure landmark: dozens of co-working spaces and fast cafe WiFi throughout Nimman and the Old City.
Bali, Indonesia: Excellent in the Right Areas
Bali’s internet situation is better than most people expect in South Bali (Seminyak, Canggu, Kuta) and Ubud, but worse than expected outside these areas. Telkomsel is the strongest network and covers tourist areas well. Data plans are cheap: 30GB for approximately 6 euros. For nomads in Canggu, Ubud, or Seminyak, Bali works well as a remote work base. A ConnectPls SIM card subscription for Indonesia gives you Telkomsel-network coverage at local pricing.
Vietnam: Cheap But With Bureaucracy
Vietnam has very cheap data and improving 4G coverage in Ho Chi Minh City, Hanoi, and Da Nang. The complication: Vietnamese SIM cards require passport registration at carrier shops on arrival. A ConnectPls eSIM avoids this process entirely — activate before departure, land in Hanoi or HCMC already connected.
Malaysia: Underrated Nomad Destination
Kuala Lumpur has genuinely excellent internet infrastructure — often overlooked in favor of Bangkok and Bali. Maxis, Celcom, and Digi all offer strong 4G throughout KL, and data pricing is very competitive. The nomad infrastructure in areas like Bangsar, KLCC, and Bukit Bintang is excellent.
