List of ISPs in Thailand

Thailand’s internet market has grown rapidly. Strong competition means you get better speeds and lower prices. We can divide the broadband providers in Thailand into two distinct groups.

Major ISPs in Thailand

These three giants dominate the market. They own the largest physical networks and serve the vast majority of households and businesses.

1. AIS-3BB Fibre3

This company is now the biggest internet service provider in Thailand. At the end of 2023, the main phone company, AIS, bought 3BB, which many people loved for home internet. They joined together in 2024 to form a single giant network.

What they do best: They combine the excellent customer service of AIS with the deep, established fiber network of 3BB.
Coverage: They reach almost every corner of the country, from city apartments in Bangkok to remote villages in the north.
Special features: The company offers significant discounts to customers who also use an AIS mobile SIM card. Many packages even come with the AIS Playbox for easy TV streaming.

2. True Online (True Gigatex)

True is a massive entertainment and communication company. They recently merged with DTAC, another giant mobile provider, making their overall network even stronger.

What they do best: True focuses on speed and entertainment bundles. They lead the market in offering 1 Gbps and 2 Gbps speeds in major cities.
Coverage: They have a very strong network in Bangkok. Almost every new apartment building in Thailand already has True fiber lines set up.
Special features: They offer excellent bundle deals. A single subscription can get you home fiber, a mobile SIM card, and a TrueVisions cable TV box with live sports and movies.

3. NT Broadband (National Telecom)

NT is a state-owned company. It formed from the merger of two historic telecom companies, TOT and CAT Telecom.

What they do best: NT runs the main underground internet cables across the country. They mainly serve schools, government buildings, and people looking for a cheap home plan.
Coverage: As the government owns them, they focus on connecting far-off villages. NT sets up networks in remote places where other companies do not go.
Special features: They sell the most affordable starter plans in the country. Customers can find an NT service office in almost every small town in Thailand.

Other ISPs in Thailand

While the big three handle most residential connections, several other internet providers in Thailand serve specific regions and larger companies.

1. Sinet

This is a highly popular regional provider. They do not cover the whole country, but they have a great reputation in specific cities.

Where they operate: Mainly in Chiang Mai, Chiang Rai, Pattaya, and parts of Northeast Thailand (Isaan).
Why choose them: Sinet built one of the first pure fiber-optic networks in Chiang Mai. They deliver high reliability and quick customer support.

2. Phuket Connect

This is a local provider that operates exclusively on Phuket Island.

Where they operate: Across Phuket.
Why choose them: Because they focus just on one province, they understand local needs. They offer fast installation and personalized customer service that the big national companies sometimes struggle to deliver.

3. UIH (United Information Highway)

UIH is a major player, but you will not usually see them advertising to home users. They focus entirely on businesses.

Who they serve: Large companies, banks, offices, and shopping malls.
Why they matter: They set up private, high-speed lines that guarantee fast speeds and direct links to global servers.

4. Symphony Communication

Similar to UIH, Symphony is a premium business-to-business Internet provider in Thailand.

Who they serve: Medium to large enterprises, cloud service providers, and international offices.
Why they matter: They operate a highly reliable nationwide fiber network. They focus on delivering super-fast connections and safe storage systems for business data.

5. GOMO and FINN Mobile

These online brands offer great alternatives to the main companies for cheap, hassle-free mobile internet.

How they work: GOMO runs on the AIS network, while FINN Mobile runs on the True-DTAC network.
Why choose them: They offer massive data packages or unlimited mobile data for a much lower price than traditional plans. Users manage everything easily through an app.

Prices of ISPs in Thailand

Internet access in this country remains highly affordable. Most internet companies in Thailand offer high-speed packages.

You can get excellent value and reliable connections for a very small monthly fee.

Yearly Contracts: Most providers require a minimum 12-month contract. If you cancel the service early, you will pay a penalty fee of about 3,000 to 4,000 Baht.
Free Installation: During promotional campaigns, companies typically offer a free router along with a discounted installation fee. When you sign up, make sure to confirm this with your provider.
Cheap Tourist SIMs: For just 299 to 499 baht, visitors can purchase prepaid SIM cards with 30 to 60 GB of data that last for 7 to 30 days.
Monthly Postpaid Plans: The monthly cost of long-term mobile plans ranges from 400 to 700 Baht. Providers slow down speeds after you use 2.5 GB or 5 GB in a day.
Frequent Updates: Prices and promotions change quickly in this competitive market, so check the provider’s website or visit a local store to get the absolute latest deals.

Coverage Areas of Thailand ISPs

Location plays a major role in choosing the right connection. While most broadband providers in Thailand offer excellent service in big cities, some companies specialize in reaching rural areas.

Checking local network maps helps secure the strongest possible signals.

Specific City Details:

Bangkok: True and AIS-3BB are everywhere. If you live in a condo, ask the building management about existing internet options.
Chiang Mai: AIS-3BB Fibre3 covers most areas well. Local options like Sinet also provide reliable service.
Phuket: AIS-3BB is strong across the island. True Gigatex might offer better deals in areas like Patong or Phuket Town. You can also look into local options like Phuket Connect.
Pattaya: True Gigatex often leads, especially in areas with many condos. AIS-3BB and CAT Telecom (now part of NT) also offer good options.
Hua Hin: Both AIS-3BB and True provide good service, particularly in newer residential areas.

Internet Speed in Thailand

Thailand has some of the fastest web connections in the world. The average internet speed in Thailand is now 237.05 Mbps. This speed is more than double the global average.

Fixed Broadband: Mobile speeds stay strong too. The average download speed reaches about 107 Mbps. In busy cities, 5G networks from AIS and True deliver speeds between 100 and 200 Mbps.
Mobile Internet: Mobile internet also works very fast. Average mobile speeds reach 107 Mbps. Both AIS and True offer 5G networks that easily attain 100 to 200 Mbps in major cities.
Stability and Latency: Internet connections in major cities remain steady with very few outages. Daily tasks run without any trouble. Only pro gamers might feel a small delay.

FAQs

I put together the most common questions about ISPs in Thailand.

Can I use my own router with Thai ISPs?

Yes, you can. Ask your provider to “bridge” their modem. This lets you connect your own router for wider Wi-Fi coverage or advanced settings.

Are all internet plans unlimited in Thailand?

Fixed home broadband plans typically offer unlimited data without caps. Mobile internet plans often advertise as “unlimited,” but they usually have a fair-use policy. This means your speed might slow down after you use a certain amount of high-speed data each day.

How long are typical internet contracts?

For fixed home internet, most providers require a minimum 12-month commitment. Some might offer shorter terms at a higher monthly price.

Is Wi-Fi available in rural areas?

Yes, connectivity is expanding rapidly in rural areas thanks to government initiatives and providers like AIS-3BB and NT Broadband. Always check availability for your specific address.

Is it easy to switch between Thai internet providers?

It depends on your contract. If you are past your minimum term, switching is usually straightforward. If you cancel early, you might pay a penalty fee.

Do I need a Thai bank account to get home internet?

While not strictly required, having a Thai bank account makes monthly payments much easier. You can often pay at 7-Eleven or the provider’s office if you do not have a local account.

Are VPNs legal in Thailand?

Yes, Thai law allows personal VPN use. Many foreign residents use them to keep their data private and secure. However, accessing blocked websites via a VPN violates the Computer Crime Act and can cause serious legal trouble.

Does Thailand have internet censorship?

Yes, Thai authorities block certain online content. This includes material deemed to threaten national security, content that violates lèse-majesté laws, pornography, and gambling sites.

Which ISP has the best mobile coverage in Thailand?

AIS is widely considered to have the most comprehensive mobile network coverage and excellent speeds. True Move H also performs very well, particularly in urban areas. NT provides good service in many remote regions.

How long does internet installation take?

In major cities, installation usually completes within two days of your application. In rural areas, it might take several weeks, especially if they have to do more infrastructure work.
