Thailand is the destination everyone has on their list but few dare to actually plan: golden temples, picture-perfect beaches, street food that changes your life, and an energy unlike anywhere else in the world. Flight searches from Mexico to Thailand grew over 140% in the past year, and it's no surprise. If you've already taken the leap and have your trip in mind, there's one thing you can't leave for the last minute: internet. In this DatosdeViaje guide we explain everything you need to know to arrive connected in Bangkok from minute one.
Thailand has a surprisingly solid telecommunications infrastructure in its cities and tourist zones, but international roaming from Mexico can cost between $25 and $100 USD per day depending on your carrier. For a two-week trip, that can turn into a bill of over $1,400 USD just for data.
An eSIM for Thailand lets you activate a data plan before boarding your flight, connect as soon as you land at Bangkok's Suvarnabhumi airport, and move around the entire country without paying extra fees or hunting for a physical SIM card. Google Maps for navigating the BTS Skytrain, WhatsApp to coordinate with your group, Google Translate for Thai menus — all available from the very first moment.
If you're not yet familiar with how an eSIM works, we recommend reading our complete beginner's guide to eSIM before continuing.

The DatosdeViaje Asia plan covers Thailand and several other countries across the continent with a single eSIM. This is a huge advantage if your itinerary includes a stopover in another Asian destination or if you want to combine Thailand with Japan, Malaysia, Singapore, or Indonesia in the same trip.
With a single purchase and a single QR code, you get internet across all included countries without needing to swap plans or reinstall anything. Even if your trip is exclusively to Thailand, the Asia plan gives you full local coverage across the entire country.

DatosdeViaje Asia plans start from $10 USD, with larger capacity options available depending on the length of your trip and how heavily you plan to use your data. You can pay in USD or MXN, which makes it very convenient for travelers departing from Mexico or anywhere in Latin America.
Thailand is a destination where you'll use your phone constantly: maps to navigate Bangkok, restaurant searches, real-time translation, ferry reservations between islands. If you're going for more than a week, we recommend a plan with more GB so you don't run out of data mid-trip. The best part about Datos de Viaje is that you can top up directly from your account without purchasing a new eSIM or reinstalling anything.

First, verify that your phone is eSIM-compatible. You can check the full list of supported models on our compatible phones page. Most iPhones from the XS onward, Samsung Galaxy from the S20, and Google Pixel from the 4 are already compatible.
Once you've confirmed compatibility, go to Asia, choose the plan that best fits your trip, and complete your purchase. You'll receive a QR code by email immediately. Scan that code from your phone's network settings and the eSIM will be installed in under 5 minutes. For detailed step-by-step instructions by phone model, visit our installation guide.
We recommend installing the eSIM one or two days before your flight. When you land in Bangkok, activate data roaming on the DatosdeViaje eSIM and you'll be connected before you even collect your luggage. No queues. No paperwork in Thai. No stress.
Thailand has one of the best telecommunications infrastructures in Southeast Asia. In Bangkok you'll have 4G and in many areas 5G signal essentially everywhere: the BTS Skytrain, the MRT metro, shopping malls, markets, and Suvarnabhumi airport. Connectivity in the capital is on par with any major European city.
In Chiang Mai coverage is excellent in the historic old city, the Night Bazaar, and the main temples. In the more rural north the signal may drop in some areas, but popular tourist destinations like Doi Inthanon and the Golden Triangle have reliable coverage. On the southern islands, Phuket, Koh Samui, and Krabi have very stable signal in tourist zones and main beaches. On smaller islands like Koh Tao or Koh Lanta the signal is more variable, especially on jungle trails heading inland.

Mexican citizens do not need a visa to enter Thailand for tourist stays of up to 60 days, which makes trip planning much simpler. You just need a valid passport with at least 6 months of validity remaining and an outbound ticket.
The local currency is the Thai baht (THB), and while credit cards are accepted at hotels and shopping malls, many street markets, local restaurants, and local transport only accept cash. It's recommended to carry some baht for the first few days. The official language is Thai, and while English works well in tourist areas, having Google Translate active on your phone is essential — especially at local restaurants and markets.
Having reliable internet from the moment you land isn't a luxury in Thailand: it's a practical travel tool. With the Datos de Viaje eSIM active you can use maps offline, book safe rides through Grab (Thailand's version of Uber), translate menus in real time, and stay in touch with family on WhatsApp without depending on hotel public networks.
Yes. With the DatosdeViaje eSIM you can turn your phone into a hotspot and share your connection with other devices — your laptop, tablet, or a travel companion's phone. Very useful if you're traveling as a couple or group and want to split the cost of a single plan.
For step-by-step instructions on how to set up the hotspot on your specific phone model, check our guide: How to share internet with your eSIM.
There are many eSIM options on the market, including competitors like Airalo or Holafly, but DatosdeViaje was built for LATAM travelers. That translates into WhatsApp support in Spanish and English available before, during, and after your trip, pricing in both USD and MXN, and the ability to top up your eSIM directly from your account without reinstalling anything.
Instant activation: purchase from Mexico and receive your QR code within minutes. You land in Bangkok, activate roaming, and you have internet. No queues at Suvarnabhumi airport. No searching for a chip store in the middle of arrival chaos. Just land and go. To learn more about how the entire purchase and activation process works, visit our guide on how DatosdeViaje works.
