Thailand mobile internet providers
Thailand has three major mobile network providers that dominate the market: AIS, TrueMove H, and DTAC. These providers offer a wide range of mobile data packages and prepaid SIM card options for both short-term and long-term use.
- AIS: Known for having the widest coverage and the fastest speeds in Thailand, AIS is the go-to provider for those who want reliable service, especially in rural and remote areas. It also offers high-speed 4G LTE and is rolling out 5G in major cities.
- TrueMove H: Another top choice, TrueMove offers strong coverage in urban areas and is particularly known for its data speeds. It’s often the preferred choice for those looking for a balance of speed and affordability.
- DTAC: DTAC is a popular choice for tourists and expats, with good coverage in urban areas and a reputation for offering affordable plans and great customer service.
Prepaid SIM Card for Thailand
An International SIM card will always be one of your best bets to stay connected to the Internet during your trip. Similar to your cell phone, a Thailand SIM card, light in size and easy to use, is made to give you high-quality Internet.
This option tends to be somewhat inexpensive and easy to use. Also, there are several different ways to purchase one, either before your trip or through an online store. We like to recommend the Holafly store for their excellent service. On the other hand, you can also purchase your SIM card once you arrive in Thailand through physical stores of local operators such as AIS, Dtac, and TrueMobile H.
AIS Traveler SIM card
This operator, well-known in Thailand, offers a SIM card that offers data service for travelers. With this SIM card, you can connect 4G and 5G. Through their website, you can find information about their SIM for your trip.
Dtac Tourist SIM Card
At the same time, the DTAC operator offers good-quality coverage. However, it is vital to remember that it is designed for travelers, Their SIM card is called Happy Tourist SIM, and they offer different plan options.
TrueMobile H Tourist SIM card
This operator is well known in the country and its cards can even be found at the airport. However, in this case, it is better to bring it from your country and not put yourself at risk while you are at the airport.
International eSIM for traveling to Thailand
An international eSIM is a digital SIM card that enables you to activate a mobile data plan from a service provider without needing a physical nano-SIM. These virtual cards are quick and easy to obtain from anywhere around the world.
With an eSIM for Thailand, you can also keep your original phone number. Your phone essentially becomes a dual SIM device, allowing you to top-up and manage your plan with ease. These eSIMs offer great convenience, as you’ll have immediate internet access upon arriving in Thailand, ensuring you’re ready to use online services without any hassle.
Simsolo’s eSIM for Thailand
If you’re looking to purchase an eSIM for Thailand, we recommend doing so through Simsolo‘s official website. Simply select the eSIM Thailand option, complete the purchase form, and within minutes, you’ll receive a QR code to activate your eSIM.
Roaming in Thailand with your local operator
Roaming in Thailand with your local mobile operator can be a convenient option if you don’t want to hassle with getting a local SIM card or portable Wi-Fi. However, it’s important to understand the costs, coverage, and potential limitations before relying on your home operator’s roaming services while traveling.
1. Coverage in Thailand
Thailand has extensive mobile coverage, especially in major cities like Bangkok, Chiang Mai, Phuket, and Pattaya, and in most popular tourist areas. You’ll find good 4G LTE coverage in these urban areas and some tourist islands. However, if you’re planning to visit more remote or rural regions, 3G or even 2G networks might be more common. Keep in mind that some smaller mobile operators may not have partnerships with Thai networks, which could limit your connectivity in certain areas.
2. Roaming Charges
One of the biggest downsides of roaming is the cost. While roaming charges vary by mobile carrier, they tend to be significantly higher than local rates for both data usage and calls. The main roaming costs you should be aware of are:
- Data Roaming: This can be very expensive. Your home operator might charge high per-megabyte or per-gigabyte rates, which can quickly add up, especially if you’re using data for navigation, social media, or streaming.
- Voice Calls: Both incoming and outgoing calls are usually more expensive when roaming. Some operators may charge extra for receiving international calls.
- Text Messages: Sending and receiving text messages can also incur extra charges while roaming.
- International Calls: If you’re calling home while in Thailand, be prepared for high international call rates as well.
3. Roaming Charges for AT&T in Thailand
Roaming charges can be quite high, and AT&T’s rates for Thailand are typically more expensive than domestic rates. Here’s what you can expect:
- Data Roaming: Data usage while roaming in Thailand can get very expensive. AT&T charges per megabyte (MB) or per gigabyte (GB) for data use. On average, AT&T’s data roaming rates are $2.05 per MB for data usage outside of any package plans, which can quickly add up if you use a lot of data for browsing, streaming, or navigation.
- Voice Calls: If you make or receive calls while in Thailand, AT&T charges $2.00 per minute for outgoing calls. Incoming calls are typically charged at a similar rate, and international calls back to the U.S. or other countries may incur additional fees.
- Text Messages: Sending a text message can cost around $0.50 per message (for both outgoing and incoming), which is relatively expensive compared to domestic rates.
4. AT&T International Roaming Plans for Thailand
AT&T offers several international roaming plans and options that can help lower your roaming costs in Thailand. Some of these options include:
AT&T International Day Pass
The International Day Pass allows you to use your existing plan’s data, text, and voice allowance while traveling abroad for a daily fee. For Thailand, the International Day Pass costs $10 per day (as of 2024). Here’s how it works:
- Data: You can use your plan’s data allowance (up to the limit of your plan) while in Thailand without additional charges.
- Calls: You can make and receive calls at the same rates as your home plan, so if you have unlimited calls on your domestic plan, you’ll have unlimited calls in Thailand.
- Texts: You can send and receive text messages at the same rate as your domestic plan, often included in your regular texting allowance.
The International Day Pass is a great option for frequent travelers or those who plan to stay in Thailand for a longer period, as it gives you access to your existing plan’s features at a daily rate.
5. T-Mobile Roaming in Thailand: What You Need to Know
If you’re a T-Mobile customer planning to visit Thailand, you’ll be pleased to know that T-Mobile offers international roaming in Thailand. T-Mobile has extensive partnerships with local Thai networks, allowing you to use your phone for calls, texts, and data while abroad. However, it’s essential to understand the costs, coverage, and available options before you travel. Here’s a complete guide to help you navigate T-Mobile roaming in Thailand.
6. T-Mobile Roaming Charges in Thailand
Roaming charges can vary depending on your T-Mobile plan and whether you’ve activated any special roaming options. Here’s a breakdown of what you can expect when using your T-Mobile service in Thailand:
7. Magenta Plans (Standard International Roaming)
If you’re on a T-Mobile Magenta plan, you get free text messages and low-cost data for international roaming, including in Thailand. However, there are limitations to be aware of:
- Texting: Sending and receiving text messages is included at no additional charge with the Magenta plan.
- Data: With Magenta, T-Mobile provides 2G data speeds (typically around 128 Kbps) at no extra charge for data roaming. While this is free, it’s relatively slow and not ideal for data-heavy tasks like video streaming, large downloads, or heavy web browsing.
- Voice Calls: For outgoing calls, you’ll be charged $0.25 per minute. Incoming calls are charged at $0.25 per minute as well.
8. Magenta Plus and Magenta Max Plans
T-Mobile’s Magenta Plus and Magenta Max plans offer a better deal for international roaming:
- Texting: Free, just like the Magenta plan.
- Data: Both the Magenta Plus and Magenta Max plans include high-speed data (up to 5GB at 4G speeds) in select countries, including Thailand. After 5GB, data speed will be reduced to 2G(up to 128 Kbps), which is useful for basic tasks like messaging and browsing but not for data-heavy applications.
- Voice Calls: Calls made from Thailand to the U.S. are charged at $0.25 per minute for both outgoing and incoming calls.
9. International Passes: T-Mobile’s “Simple Global” and “T-Mobile Travel Pass”

For $5 per day, you get high-speed data (up to 5GB) and unlimited texting at no additional charge. This plan also includes voice calls at $0.25 per minute.
Pocket Wi-Fi in Thailand: Stay Connected Anytime, Anywhere
Portable Wi-Fi, also known as mobile hotspots or pocket Wi-Fi, is an excellent solution for travelers who need reliable internet access on the go in Thailand. Whether you’re exploring Bangkok’s bustling streets, relaxing on a remote island, or working remotely from Chiang Mai, portable Wi-Fi devices provide a fast, secure, and flexible way to stay connected. Here’s everything you need to know about renting or purchasing portable Wi-Fi in Thailand.
1. What is Pocket Wi-Fi?
A portable Wi-Fi hotspot is a small, battery-powered device that connects to local mobile networks (usually 3G, 4G LTE, or even 5G) and allows you to access the internet on multiple devices simultaneously, such as smartphones, laptops, and tablets. You can rent or buy a portable Wi-Fi device in Thailand, ensuring seamless internet access no matter where you are.
2. Where to Rent Pocket Wi-Fi in Thailand

Several service providers have kiosks or counters at these locations where you can rent a device for the duration of your stay.
- Online Rental Services: Many companies offer the option to book a portable Wi-Fi device online, which can be delivered to your hotel or accommodation in advance. Popular services include:

- No Need for SIM Cards: Renting a portable Wi-Fi device means you don’t need to deal with local SIM cards or data plans. It’s a hassle-free way to get internet access without the need to constantly top up or switch SIM cards.

- Wide Coverage: Most portable Wi-Fi devices provide excellent 3G or 4G LTE coverage throughout Thailand, including tourist hotspots, islands, and more remote areas, where Wi-Fi in hotels or public places may not be as reliable.
- Security: Portable Wi-Fi is more secure than using free public Wi-Fi networks in cafés, airports, or other public spaces. It ensures that your connection is private and less susceptible to potential security risks.
4. Pricing for Portable Wi-Fi Rental in Thailand
The cost of renting portable Wi-Fi in Thailand depends on the duration of your rental and the data allowance provided. On average, here’s what you can expect:

- Pricing: Most co-working spaces offer flexible membership options, with daily, weekly, or monthly rates. Some also provide free trials for first-time visitors.
