Mobile connectivity in Southeast Asia
Southeast Asia's connectivity varies from world-class (Singapore with 5G nationwide coverage) to limited (rural Laos and Myanmar). Thailand's AIS, DTAC, and True Move H give solid 4G across Bangkok, Chiang Mai, Phuket, Koh Samui, and most tourist islands.
Bali's Telkomsel has 4G in Kuta, Seminyak, Ubud, and Canggu but can be patchy in northern Bali. Vietnam's Viettel and Mobifone cover Ho Chi Minh City, Hanoi, and Ha Long Bay well. Cambodia's Smart Axiata and Cellcard have 4G in Phnom Penh and Siem Reap.
Vodacom and MTN roaming in Southeast Asia costs R 55 to R 110 per day, with limited data before throttling. A HelloRoam Southeast Asia eSIM covers multiple countries on one plan with local network speeds.
- Singapore has the best mobile coverage in Southeast Asia with nationwide 5G
- Thailand's AIS and DTAC cover all major tourist areas with solid 4G
- Bali has 4G in tourist zones but patchy in rural northern Bali
- Vodacom and MTN Southeast Asia roaming: R 55 to R 110 per day
- Multi-country HelloRoam plans cover 10+ SEA countries on one eSIM

eSIM Travel Tips for Southeast Asia
Thailand tourist SIMs are available at Bangkok's Suvarnabhumi airport
AIS, DTAC, and True Move H all sell tourist SIM cards at Suvarnabhumi airport counters for 299 to 499 Thai Baht (R 130 to R 220). These are good value for Thailand-only travel. For a multi-country trip covering Thailand, Bali, and Vietnam, a HelloRoam regional plan is more practical.
Download Grab before you land in any Southeast Asian city
Grab is the dominant ridehailing app across Southeast Asia. Use it in Bangkok, Kuala Lumpur, Singapore, Jakarta, and Phnom Penh. It is safer and more transparent than negotiating with tuk-tuk drivers or unlicensed taxis. Grab requires a live data connection to book rides.
Street food safety is high in Thailand, Singapore, and Malaysia
Southeast Asia's street food scene is world-class. In Thailand, Singapore, and Malaysia, licensed hawker centres and food courts have high hygiene standards. Use Google Maps reviews on your data connection to identify the best stalls in each area.
Bali's scooter rental is fun but check your travel insurance
Scooter rental is the most common way to get around Bali and other smaller islands. Most South African travel insurance policies exclude motorbike accidents unless you have motorcycle cover added. Check your policy before renting.
Vietnam's north-to-south journey takes at least 10 days
Vietnam stretches 1,650 km from Hanoi to Ho Chi Minh City. If you want to see both cities plus Ha Long Bay, Hoi An, and Da Nang, allow a minimum of 10 to 14 days. Domestic flights on VietJet and Vietnam Airlines are cheap and frequent. Your data connection handles booking and check-in.
Southeast Asia mobile networks: what South Africans need to know
Thailand's AIS uses LTE Band 1 (2100 MHz), Band 3 (1800 MHz), and Band 8 (900 MHz), all well-supported by South African Samsung Galaxy and iPhone models. Bali's Telkomsel runs Band 1 and Band 3. Singapore's Singtel, StarHub, and M1 operate 5G on n1 and n78, with 4G as the universal fallback. Malaysia's Maxis, Celcom, and Digi use Band 3 and Band 1. Vietnam's Viettel runs LTE Band 1 and Band 3. Cambodia's Smart Axiata and Cellcard use Band 3. The LTE Band 3 (1800 MHz) is the most commonly used band across Southeast Asia and is supported by virtually every South African phone. South Africans can confidently expect solid 4G connectivity on any modern Android or iPhone across the main tourist corridors of Southeast Asia. Where coverage drops is in national parks, remote islands, and highland areas more than an hour from a major city.

When South Africans visit Southeast Asia
South Africa's summer school holidays (December to January) align with Thailand and Bali's dry season, making December to February the peak booking period from South Africa. The June to July SA winter school holidays catch Bali at its best (dry season). Thailand's wet season (June to October) does not affect all areas equally: the east coast (Koh Samui, Koh Tao) is dry while the west coast (Phuket, Krabi) is wet. Vietnam follows different monsoon patterns entirely.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
