Mobile connectivity guide for Thailand
Thailand has excellent 5G and 4G coverage throughout its tourist destinations. AIS and True Corporation (operating the TrueMove H and dtac brands) cover Bangkok, Phuket, Koh Samui, Chiang Mai, Pai, and all the popular Singapore expat holiday spots.
Bangkok's 4G and 5G coverage is strong throughout the city centre. Island areas are well covered in resort zones. A HelloRoam eSIM beats buying a Thai SIM at Suvarnabhumi Airport after your Scoot flight from Changi.
- HelloRoam connects to AIS 5G, DTAC 5G, True Move 4G in Thailand

eSIM Travel Tips for Thailand
Thailand is a quick hop from Singapore: sort your eSIM before you go
Singapore to Bangkok is about 2.5 hours on Scoot. Sort your HelloRoam eSIM the night before you fly from Changi. Enable data when you land at Suvarnabhumi or Don Mueang and Grab works immediately. No queue at a SIM counter needed.
Grab Thailand is essential for BTS navigation
Bangkok's traffic can be very jialat (troublesome). Grab is the best way to get around alongside the BTS Skytrain. Both need live data. Your HelloRoam eSIM keeps Grab and the BTS Skytrain app running from the moment you land at Suvarnabhumi.
Phuket island coverage is good
Phuket's main beach areas including Patong, Kata, and Karon have strong 4G. Boat trips to Phi Phi Island and the James Bond Islands in Phang Nga Bay drop signal on open water. Download your tour itinerary and island maps before boarding from Ao Chalong pier.
Chiang Mai night markets and tuk-tuks
Chiang Mai city has excellent 4G and 5G coverage throughout the old city moat area, Nimman district, and the night markets. Grab and local tuk-tuk booking apps work well. Remote trek destinations north of the city have limited signal.
SG long weekends are best with a plan ready to go
Singapore's public holidays like Deepavali, Chinese New Year, and Hari Raya often turn into Thailand long weekends for Singaporeans. Buy your HelloRoam eSIM well before any long weekend peak and activate it at home so you are ready to go from Changi T1 or T3.
Mobile networks in Thailand: what Singapore travellers need to know
HelloRoam connects on AIS, TrueMove H, and dtac in Thailand. AIS and True Corporation (which operates TrueMove H and dtac) are Thailand's two main network groups with strong 5G in Bangkok and tourist centres and good 4G on islands and rural areas. Multiple network options provide good coverage redundancy throughout Thailand. Your eSIM selects the strongest available signal.

Singapore's school holiday periods in June and November/December are peak times for SG families heading to Thailand.
