eSIM coverage guide for Southeast Asia from NZ
Southeast Asia is one of the most popular long-haul destinations for Kiwi travellers. Thailand, Bali, Vietnam, and Singapore top the list.
A HelloRoam Southeast Asia regional eSIM replaces the hassle of buying a new SIM at every border with one plan that switches carriers automatically as you move between countries.
Singapore has near-perfect 4G and 5G from Singtel, StarHub, and M1. Changi Airport is one of the world's best-connected airports and is a natural first stop to confirm your eSIM is working before heading to countries with lower coverage quality.
Thailand's AIS, DTAC, and True Move cover Bangkok, Chiang Mai, Phuket, and Pattaya well. Popular islands like Koh Samui, Koh Phangan, and Koh Lanta have 4G in resort areas. Remote northern highlands near Myanmar and Laos borders have gaps.
Indonesia presents the biggest challenge. Bali, Java (Jakarta, Yogyakarta), and Sumatra connect to Telkomsel and Indosat 4G reliably. But Indonesia's 17,000+ islands mean outer provinces like Papua and remote Sulawesi have very poor coverage.
Vietnam's Viettel, Mobifone, and Vietnamobile serve Ho Chi Minh City, Hanoi, Hoi An, and Da Nang well. Northern mountain provinces (Sapa, Ha Giang) have variable coverage in rural valley passes.
Cambodia, Laos, and Myanmar have the region's most limited networks. Main cities and tourist hubs have functional 4G. Rural areas often have no signal. Download everything before you go.
- Covers all 11 Southeast Asian countries on one plan
- Singapore is the region's most reliable 5G hub, perfect for OE stopovers
- Bali, Bangkok, Phuket, and Vietnam's coast are well-covered
- Island hopping means losing data between ferry stops offshore
- Indonesia's outer islands have very limited coverage
- Download offline maps before entering Cambodia, Laos, and Myanmar rural areas

eSIM Travel Tips for Southeast Asia
Sort your eSIM before leaving New Zealand
Buy and install your HelloRoam Southeast Asia eSIM at home over your home Wi-Fi before you fly from Auckland or Christchurch. You land in Bangkok or Singapore already connected. No airport SIM queue, no messaging delays back home, no stressful first hour without data.
No data on island ferry crossings
Ferry routes between Southeast Asian islands have no mobile coverage once you leave the harbour. This includes Thai Gulf islands, Bali to Lombok, Gili Islands, and Philippine inter-island ferries. Download guesthouse addresses, ferry timetables, and offline maps for your destination island before boarding. GPS keeps working from your phone's hardware without data.
Bali's tourist areas are well-covered
Kuta, Seminyak, Ubud, Canggu, and Uluwatu connect to Telkomsel and Indosat 4G reliably. Rice terrace areas around Tegallalang have coverage. Nusa Penida and Nusa Lembongan have more limited coverage, particularly on southern cliffs and hiking tracks. Download offline maps for Nusa Penida before you head out.
Singapore is your reliability checkpoint
When transiting through Changi Airport, test your HelloRoam eSIM thoroughly. Singapore's network is near-flawless and any eSIM setup issues show up clearly here. Resolving problems in Singapore (with excellent airport Wi-Fi as backup) is far easier than discovering them after arriving in Cambodia or Laos.
Thailand's northern highlands have coverage gaps
The Golden Triangle area near Thailand's borders with Myanmar and Laos has limited 4G. Chiang Rai city centre is covered but mountain villages and border crossing areas have gaps. Download offline maps before departing for remote northern routes.
Vietnam's Ha Giang Loop has variable signal
Ha Giang's main town has Viettel and Mobifone 4G. The famous Ha Giang Loop motorbike route through northern mountain valleys has variable 4G in larger villages and no signal in remote valley passes. Download your entire loop route offline before starting.
Emergency numbers vary across Southeast Asia
Emergency numbers differ by country across Southeast Asia. Thailand: 191 (police), 1669 (ambulance). Vietnam: 113 (police), 115 (ambulance). Indonesia: 110 (police), 118 (ambulance). Philippines: 911. Singapore: 999. Cambodia: 117 (police). Save the correct number for each country you visit.
Mobile network coverage across Southeast Asia
Southeast Asia varies from Singapore's world-class 5G to Myanmar's rebuilding network infrastructure.
Singapore's three operators (Singtel, StarHub, M1) compete in a small but dense market with very fast speeds and near-perfect coverage across the island.
Thailand's AIS leads in GSMA coverage rankings for the region. Bangkok and resort areas have reliable 4G. Vietnam's Viettel has grown fast with strong 4G in Hanoi and Ho Chi Minh City. Malaysia's Maxis, Celcom, and Digi cover Kuala Lumpur and the peninsula well.
Indonesia's Telkomsel reaches Java and Bali excellently but outer islands very poorly. The Philippines' Globe Telecom and Smart Communications have improved significantly but typhoon-affected rural areas remain patchy.
Cambodia, Laos, and Myanmar have functional 4G in cities but very limited rural reach.

HelloRoam Southeast Asia eSIM vs buying SIMs country by country
For a multi-country SE Asia trip from New Zealand, a regional eSIM is simpler and cheaper than buying a SIM at each border.
Recommended—
One plan covers 11 countries. Buy before leaving New Zealand, activate at home, arrive connected. No border stop for a new SIM. Automatic carrier switching. One consistent cost for the whole trip.
—
Buying a separate SIM in Thailand, Vietnam, Bali, and Cambodia means airport queues, passport registration in some countries, losing your number each time, and total costs that add up across the trip.
—
NZ carrier roaming in Southeast Asia can cost $8 to $15 per day. For a two-week Kiwi SE Asia holiday this could add $112 to $210 to your bill. A HelloRoam regional eSIM is far better value.
