Van life and extended road trips in Southeast Asia have a different character than European van life. You’re more likely to be in a rented campervan, a converted minibus, or hopping between rental vehicles than in a self-built van. The internet infrastructure — though rapidly improving — has specific characteristics worth understanding before you leave.
The headline: Southeast Asia has some of the cheapest mobile data in the world, and urban coverage is excellent. The challenge is rural and island coverage, which varies dramatically between and within countries.
Key Takeaways
- Southeast Asia has some of the world’s cheapest mobile data — under 5 euros per month in Thailand
- Urban and highway coverage is generally excellent across all major countries
- Islands and rural areas have significant coverage gaps — plan accordingly
- A ConnectPls eSIM covers arrival connectivity; local SIM cards give best long-term value
- ConnectPls covers Thailand, Indonesia, Vietnam, Malaysia, and all major SEA destinations
Thailand: The Best Base for Southeast Asia Road Trips
Thailand has the best data pricing in Southeast Asia for road trippers. AIS is the strongest carrier nationally — good coverage on major highways, in national parks, and on popular tourist islands. Data plans are extraordinarily cheap: 30-day unlimited data for 8-14 euros. A ConnectPls eSIM or SIM card subscription for Thailand connects you from landing at Suvarnabhumi or Chiang Mai.
Indonesia: Excellent on Bali, Variable Elsewhere
Indonesia’s geography — over 17,000 islands — makes mobile coverage inherently uneven. Telkomsel is the strongest carrier nationally with the widest island and rural reach. Java and Bali have excellent coverage including most of the popular tourist routes. For Bali-focused road trips, a ConnectPls SIM card gives you Telkomsel coverage at local pricing.
Vietnam: Cheap Data, Registration Required
Vietnam’s Ho Chi Minh City to Hanoi coastal route has good coverage along the main road. Viettel is the strongest carrier nationally. Data is very cheap (under 5 euros per month for 20GB). The catch: Vietnamese SIM cards require passport registration at a carrier shop. A ConnectPls eSIM for Vietnam sidesteps this requirement entirely.
Malaysia: Underrated Road Trip Destination
Malaysia’s road network is excellent and mobile coverage is strong throughout Peninsula Malaysia. Maxis has the strongest overall coverage. Data pricing is competitive — 30GB for 6-11 euros per month. East Malaysia (Borneo) has coverage in towns and along main roads, with gaps in jungle and mountain areas.
