Thailand eSIM for Canadians: Bangkok, Phuket, Islands (2026)
Thailand eSIM for Canadians: avoid $16 to $18 a day in roaming. AIS, dtac and TrueMove H 5G in Bangkok, Phuket and the islands, plus data needs and setup.
ArriGo team 10 min read Updated
The best Thailand eSIM for Canadians is a prepaid, data-only plan that connects to Thailand’s main networks, AIS, dtac and TrueMove H, with 5G in the cities, and installs on your phone before you leave home. It costs far less than the $16 to $18 a day that Bell, Rogers and Telus charge for international roaming in Thailand.
Thailand trips from Canada are long, often two or three weeks split between Bangkok, the north and the islands. That is a lot of days at a daily roaming rate. This guide explains what roaming costs, how the Thai networks compare, what to expect in Bangkok and Phuket, how much data you need and how to set up your Thailand eSIM in a few minutes.
Key takeaways
- Thailand is international roaming for Canadian carriers: $16 a day with Bell and $18 a day with Rogers or Telus, per phone.
- Thailand has three mobile brands: AIS, dtac and TrueMove H. dtac and TrueMove H now belong to the same company but still operate as separate brands. Our plans connect to all three, with 5G.
- One Thailand eSIM covers Bangkok, Chiang Mai, Phuket, Krabi and the Gulf islands.
- Install the eSIM at home on Wi-Fi before the long flight. Your plan’s days only start when it first connects in Thailand.
How much does roaming in Thailand cost for Canadians?
Bell, Rogers and Telus all bill Thailand at their international rate, which is higher than their US rate. You pay for each day your Canadian line uses data, calls or texts abroad, and the Government of Canada’s guide to using mobile devices abroad warns that apps can use data in the background without you noticing.
| Carrier and plan | Daily rate in Thailand | 7 days | 14 days | 21 days |
|---|---|---|---|---|
| Bell Roam Better | $16 | $112 | $224 | $320 (20-day cap) |
| Rogers (daily roaming) | $18 | $126 | $252 | $378 |
| Telus Easy Roam | $18 | $126 | $252 | $378 |
Canadian dollars before tax, October 2026 rates, per phone. Bell stops charging after 20 days per line in a billing period, according to its travel page; a trip that spans two billing periods can be charged more. Rogers also sells International Travel Passes ($45 for 3 days, $75 for 7, $100 for 14, $120 for 30) that cost less than its daily rate on a long trip; see Rogers’ roaming page.
For a couple on a three-week trip, daily roaming comes to roughly $640 to $760, and a family of four pays double that. Our Bell, Rogers and Telus roaming vs eSIM guide has a calculator for your exact dates.
What is the best eSIM for Thailand?
A good Thailand eSIM runs on the networks with the widest coverage, gives you enough data for maps and ride-hailing and starts counting only when you land. When you compare plans, look at:
- Network access: a plan that can use more than one Thai network gives your phone a fallback on islands and in the hills.
- 5G in the cities: useful in Bangkok, where you will use maps, ride apps and translation all day.
- Validity that starts on arrival: install at home and land in Bangkok or Phuket with data already working.
- Hotspot: handy if you carry a laptop or tablet, or want to share data with a partner.
- Plan size: long trips and heavy map use call for more data than a European city break.
Our Thailand plans connect to AIS, dtac and TrueMove H, with 5G. Your phone joins whichever network has the strongest signal where you are. Plans are data-only, so your Canadian number stays on the phone for calls and texts, and the days start when the eSIM first connects in Thailand.
The plan page lists every network and shows whether hotspot is included under “Coverage & networks”. If you are unsure about your phone, run it through our compatibility checker first.
AIS, dtac or TrueMove H: which Thai network is best?
Thailand’s mobile market has two companies but three brands. AIS is one operator. dtac and TrueMove H merged into True Corporation, and dtac’s own merger FAQ confirms that the two will continue as separate brands under the Thai regulator’s conditions. The same FAQ says the combination aims to widen coverage and improve 5G and 4G signal quality.
| Brand | Owner | Our Thailand plans |
|---|---|---|
| AIS | Advanced Info Service | Connects, with 5G |
| dtac | True Corporation | Connects, with 5G |
| TrueMove H | True Corporation | Connects, with 5G |
For a traveller, the useful point is that a plan which can reach all three brands rarely leaves you without a choice of network. If one is weak on a particular beach, ferry pier or mountain road, your phone can try another. You can see every operator our plans use on our mobile networks page, and our guide to which network to choose explains how multi-network plans behave.
If you are wondering whether 5G is worth caring about on holiday, our guide to 5G vs 4G when travelling explains when the faster network actually makes a difference.
Bangkok eSIM: getting around the city
Bangkok is huge, hot and busy, and a Bangkok eSIM is what makes it manageable. You will use data to plan BTS Skytrain and MRT routes, book ride-hailing cars and motorbike taxis, find river boat piers, translate menus and check temple opening hours.
A few practical points for Bangkok:
- Book rides in an app. Ride-hailing apps show the price before you get in, which removes the haggling and lets you share your trip with someone at home.
- Confirm prices before ordering. The Government of Canada’s travel advice for Thailand warns travellers to confirm drink and bar prices before ordering and to avoid running a tab, and says gem and jewellery scams are common.
- Protect your PIN. The same page reports credit card and ATM fraud, and advises covering the keypad and using ATMs in well-lit public places.
Tip: Download Thai in Google Translate and save Bangkok as an offline map while you are still on Wi-Fi at home. Both keep working if your signal drops in a busy market or underground station.
Phuket eSIM and the islands
Phuket, Krabi, Koh Phi Phi, Koh Samui and Koh Lanta are on most first-time itineraries, and a Phuket eSIM is simply your Thailand plan working in the south. You will use it to book ferries and longtail boats, find your resort, check the weather and keep in touch on day trips.
Data matters for safety here too. The Government of Canada reports strong riptides in Phuket, Koh Samui and Pattaya, with several drownings, and tells swimmers not to enter the water when a red flag is up. It also reports deaths from jellyfish stings around Phuket, Krabi, Koh Phi Phi, Koh Lanta and Koh Pha Ngan, and robberies and assaults at full moon parties on Koh Pha Ngan and Koh Tao.
Signal on boat trips, in national parks and on quiet beaches is never guaranteed, so before an island day:
- Download offline maps for the islands you are visiting.
- Screenshot ferry tickets and hotel bookings in case you lose signal at the pier.
- Carry a small battery pack, since maps and photos drain your phone quickly in the heat.
Before you fly: entry rules and emergency numbers
Check your entry requirements before you book. At the time of writing, the Government of Canada’s advice for Thailand says Canadians can enter for tourism without a visa for up to 30 days, which an immigration officer may extend by up to 30 more. Your passport must be valid for at least six months when you arrive.
All travellers must also complete a digital arrival card online before landing, according to the same page. You fill it in on Thailand’s official Digital Arrival Card website, so having data or Wi-Fi before your flight matters. Rules change, so confirm the details shortly before you travel.
Save these Thai emergency numbers from the Government of Canada’s advice page:
| Service | Number |
|---|---|
| Police | 191 |
| Tourist police | 1155 |
| Ambulance and medical help | 1669 |
| Fire | 199 |
| Tourism Authority of Thailand (English) | 1672, then press 9 |
The rainy season runs from June to November and can bring flooding, impassable roads and damaged bridges, so keep data on to follow weather alerts and road news if you travel in those months.
How much data do you need in Thailand?
Thailand trips usually last longer than a European city break, and travellers lean on their phones for transport, translation and bookings every day. As a rough guide for one phone:
| Type of trip | Typical use | Suggested data |
|---|---|---|
| One week, Bangkok and a beach | Maps, ride apps, messages, photos | 5 GB |
| Two weeks, Bangkok, Chiang Mai and islands | Daily navigation, translation, social media | 8 to 15 GB |
| Three weeks or longer | Heavy maps use, video calls home, uploads | 15 to 20 GB |
| Working remotely or sharing a hotspot | Video calls, cloud files, laptop use | 20 GB or more |
Video and camera translation use the most data. Set photo backup to Wi-Fi only and pause app updates over mobile data. Our guide to how much data you need when travelling breaks usage down by app, and if your family wants to share one connection, read our guide to sharing mobile data abroad.
How to set up your Thailand eSIM before you fly
Setup takes about five minutes on home Wi-Fi, and doing it before the long flight means you land with data ready. The validity only starts when the eSIM first connects in Thailand, so installing it early costs nothing.
- Check your phone. It needs eSIM support and must be unlocked. Use our compatibility checker or our guide to checking if your phone is eSIM compatible.
- Buy your Thailand plan. The QR code arrives by email, usually within about a minute. Travelling as a group? You can buy up to 10 eSIMs in one order and send each QR code to its own email.
- Install it on Wi-Fi. On iPhone, follow Apple’s eSIM setup guide. On Android, open Settings, find SIM manager or Network and internet, and add an eSIM by scanning the code.
- Label your lines. Name the new one “Thailand” and your usual one “Canada”.
- When you land, turn on the Thailand line, enable data roaming for it and set it as your mobile data line.
- Turn data roaming off on your Canadian line, especially during any stopover, so your carrier can’t start a daily charge.
Apple’s guide to using Dual SIM with an eSIM explains how your Canadian line can stay on for texts, including bank codes, while the Thailand eSIM carries your data. Our guide to keeping your Canadian number with a dual SIM explains the set-up in more detail.
For phone-by-phone steps, read our guide to installing an eSIM before you fly. If the eSIM does not connect on arrival, try our eSIM not working abroad fixes or visit the help centre.
Visiting Thailand as part of a bigger Asia trip?
A Thailand plan covers Thailand only. Many Canadians combine Thailand with Vietnam, Cambodia, Japan or a stopover elsewhere in Asia. For a multi-country route, look at our global plans, which list every country covered, or pick a plan for each stop from our destinations list. Heading to Japan as well? Our Japan eSIM guide covers it.
Your next step
Check your phone with our compatibility checker, then compare every Thailand eSIM plan by data and validity. Install it at home on Wi-Fi, switch it on when you land in Bangkok or Phuket, and keep your Canadian line’s data roaming off for the whole trip.
Frequently asked questions
Which networks does a Thailand eSIM use?
Our Thailand plans connect to AIS, dtac and TrueMove H, with 5G. Your phone joins whichever has the strongest signal where you are, so you are covered by all three of Thailand's mobile brands.
Is Thailand included in Canadian carriers' roaming?
Yes, but at the international rate: $16 a day with Bell and $18 a day with Rogers or Telus, per phone, as of October 2026. On a two- or three-week trip that adds up quickly, which is why many travellers use a prepaid eSIM instead.
Does a Thailand eSIM work in Phuket and on the islands?
Yes. A Thailand plan covers the whole country, including Phuket, Krabi, Koh Samui and Chiang Mai. Signal can drop on boat trips, in national parks and on remote beaches, so download offline maps before you go.
Do I get a Thai phone number with a travel eSIM?
No. Our plans are data-only, so your Canadian number stays on your phone for calls and texts. Messaging apps such as WhatsApp, LINE and iMessage work over the eSIM data.
How much data do I need for two weeks in Thailand?
As a rough guide, two weeks with Wi-Fi at your hotel needs about 8 to 15 GB per phone for maps, ride-hailing, translation and social media. Choose more if you stream video or share a hotspot with a laptop.
Can I install my Thailand eSIM before leaving Canada?
Yes. Install it at home on Wi-Fi before the long flight. The plan's days only start counting when the eSIM first connects to a network in Thailand.
