Is a Thailand SIM card from Suvarnabhumi better than an eSIM for Indian tourists visiting Bangkok?

Plans run on AIS, DTAC, TrueMove H, and 1 more 5G from ₹332.16 with no hidden charges and no Airtel or Jio roaming fees.

Mobile connectivity guide for Thailand
Thailand is one of the most popular holiday destinations for Indian travellers, offering affordable packages, beach resorts, and street food culture. AIS and True Corporation (running TrueMove H and dtac) provide 5G and 4G LTE across Bangkok, Phuket, Pattaya, Koh Samui, and Chiang Mai.
A HelloRoam eSIM activates the moment you land at Suvarnabhumi Airport, giving you instant access to Grab, maps, and hotel bookings across popular tourist zones.
- HelloRoam connects to AIS 5G, DTAC 5G, TrueMove H 5G and 1 more in Thailand

eSIM Travel Tips for Thailand
Install your eSIM before you fly from India
Flights from Indian cities to Bangkok are 3 to 4 hours. Set up your HelloRoam eSIM at home before you depart. Enable data at Suvarnabhumi Airport and you can book your taxi or Grab ride before you even exit arrivals.
Grab is the most useful app in Thailand
Grab is the dominant ride-hailing and food delivery app in Thailand. Having a working data connection from the moment you land makes booking airport transfers, local rides, and meal deliveries very straightforward.
Island coverage varies
Phuket, Koh Samui, Koh Phangan, and Koh Lanta have 4G coverage in tourist areas. Remote beaches and smaller islands can have limited signal. Download offline maps before island hopping, especially for Koh Tao or the Similan Islands.
Thailand is very affordable for Indian travellers
Data costs are low relative to Indian currency. HelloRoam plans for Thailand are affordable for a short holiday, and budget travellers can extend their data plan inside the app if they need more without buying a new SIM.
Use your Indian SIM for calls home
Keep your Jio or Airtel SIM active in slot 2 for receiving family calls on your Indian number. Set HelloRoam as the data line for Thailand. This dual approach saves money compared to activating full international roaming on your Indian plan.
Mobile networks in Thailand: coverage for Indian visitors
Thailand has two major network groups: AIS and True Corporation. True and dtac completed their corporate merger in March 2023, forming True Corporation, which runs both the TrueMove H and dtac brands. AIS provides extensive rural and island coverage. TrueMove H (True Corporation) offers strong 5G in Bangkok and major cities. HelloRoam connects on AIS (5G), dtac (5G), and True Move (4G), and your phone picks the strongest available network automatically based on where you are in Thailand.

HelloRoam eSIM vs Airtel roaming vs Thai local SIM
A straightforward cost comparison for Indian tourists heading to Thailand.
| Category | HelloRoam eSIM | Thai tourist SIM (AIS or TrueMove H) | Jio/Airtel international roaming for Thailand |
|---|---|---|---|
| Typical cost | From ₹335.02 total | ₹761.40–₹2,664.90 total | ₹951.75–₹1,903.50/day |
| Details | Plans start at ₹332.16. Buy online in India, scan the QR code, and land in Bangkok already connected. Much cheaper than Indian carrier roaming for a 5 to 7 day Thailand holiday. | Tourist SIMs at Suvarnabhumi Airport cost THB 299 to 599 (₹700 to ₹1,400). They work well but require arrival-hall purchase time. An eSIM eliminates this hassle entirely. | Jio Thailand roaming packs start around ₹575 for limited data. Airtel charges ₹699 per day or offers weekly packs around ₹3,000. HelloRoam delivers better value for most holiday trip lengths. |
Prices approximate as of . Actual savings vary.
Best time to visit Thailand from India
November to February is the best season for most of Thailand, with dry weather and temperatures of 25°C to 32°C. March to May is hot and humid. June to October is rainy season, though the west coast (Phuket, Krabi) has its wet season earlier and the east coast (Koh Samui) experiences rain later. Indian travellers often visit during Diwali and December holidays when flight prices are higher but weather is excellent.

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!!

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.
