Fibre broadband is widely available in Thai cities and towns, and most long-stay residents get it as a monthly contract with one of the big providers: AIS Fibre (which now also owns 3BB), True Online or the state company NT. Contracts usually run for 12 or 24 months, a technician installs the line and lends you a router, and the router goes back when you cancel.
For a short stay, a phone hotspot or the building's Wi-Fi is usually enough; our guide to internet, Wi-Fi and VPNs in Thailand covers that, and our older article compares a Thai SIM card and an eSIM. This page is about a fixed line in your own name, for people who rent a condo or house for months or years and work from home, stream or simply want a connection that does not depend on a data allowance.

The providers: AIS, 3BB, True and NT
Thailand's home broadband market is dominated by a few large companies.
- AIS Fibre is the fixed-line arm of the mobile operator AIS. AIS bought Triple T Broadband, the company behind 3BB, and 3BB's own website now sells the same AIS packages. If you already have a 3BB line, ask the provider how your contract is affected before you change plan.
- True Online is the home internet service of True, which also runs the True and dtac mobile brands.
- NT Broadband is the fibre service of National Telecom (NT), the state-owned telecom company.
Which one you choose depends mostly on which fibre reaches your building. In a condo, the juristic office (building management) can tell you which providers already have cables in the building. Choosing one of those usually means a quicker, simpler installation.
Prices and contract terms: one dated example
Prices change with promotions, so treat any list as a snapshot. AIS's BROADBAND24 packages, as shown on its own website on 19 October 2026, illustrate how speed, price and contract length interact:
| Speed (download/upload) | Monthly price | Contract |
|---|---|---|
| 300/300 Mbps | ฿499 | 12 months |
| 500/500 Mbps | ฿500 | 24 months |
| 500/500 Mbps | ฿600 | 12 months |
| 1 Gbps/500 Mbps | ฿600 | 24 months |
| 1 Gbps/500 Mbps | ฿700 | 12 months |
| 1 Gbps/1 Gbps | ฿1,200 | 12 months |
The page did not say whether VAT is included, so ask. The packages included AIS's Secure Net service, a discount on outdoor wiring for installation (valued at 4,800 baht) and a router on loan. For how the internet bill fits into a month's spending, see our guide to the cost of living in Thailand.
The pattern matters more than the numbers. A 24-month contract gives more speed for the money, but only makes sense if you expect to stay in the same place for two years. If your lease is for one year, a 12-month contract, or a provider that lets you move the line to a new address, is the safer choice.
Documents and paperwork for foreigners
We could not find an official page from AIS, True, 3BB or NT that lists the documents a foreign customer needs, and we do not repeat the lists published by resellers. In practice, bring your passport with your current visa or extension stamp, and ask the provider before the appointment which other documents they want. Have these ready in case:
- Your lease, showing the address where the line will be installed.
- A work permit, if you have one.
- A Thai phone number in your name, for the account, text messages and the technician's calls.
- Your full address written in Thai, which our guide to how Thai addresses work helps you read.
Ask too how you can pay the monthly bill. Thai banking apps and payment by QR code at convenience stores are common ways to pay bills, so opening a Thai bank account makes life easier, but ask whether a foreign credit card is accepted if you do not have one. Apply at a provider's shop in a mall, by phone or online; a shop visit is often simplest for a first contract, because staff can copy your passport there.
What to check before you sign
Read the contract, or ask staff to show you these points, before you sign:
- The total monthly price with VAT, and what happens to the price after any promotional period.
- The minimum contract period and the fee for cancelling early. We could not verify standard early-termination fees, so get the figure in writing.
- Any installation fee, and whether it is waived for the contract you choose.
- What equipment is on loan (router, mesh units, TV box) and what you pay if it is lost or damaged.
- Whether the line can move with you to a new address, and what that costs.
- How to cancel: in a shop, by phone or online, and how much notice is needed.
The router is borrowed, not bought. AIS states that its lent router must be returned when you cancel. Keep the box and the receipt, and return the equipment in person when you leave Thailand or move out, or you may be charged for it.
Installation in a condo or house
After you sign, the provider books a technician. In a condo, the installer usually needs access to the telecom room or cable riser on your floor, so tell the juristic office the date in advance; some buildings require a permission form or a deposit for contractors. In a house, the cable may come from the nearest pole outside, which is the outdoor wiring AIS was discounting.
Ask the landlord before any drilling, and agree where the cable will run and where the router will sit. A router in the middle of the home, high up and away from the kitchen, gives better Wi-Fi than one hidden in a cupboard by the front door. Our guide to renting a condo or house covers what to agree with the owner, and notes that internet is sometimes included in the rent or arranged by the building.
Ask the building first. If the condo already has a bulk internet deal or a provider's cable on every floor, the cheapest and fastest option may be that one, even if another brand advertises a lower price.
Routers, Wi-Fi and working from home
The lent router is usually good enough for a one-bedroom condo. In a larger house or a unit with thick concrete walls, ask the provider about mesh units, or add your own, and connect your work computer by cable where you can. Many people who work online keep the provider's router for the line and put their own Wi-Fi system behind it.
If you hold a Destination Thailand Visa or otherwise work remotely, consider the internet a work tool: test the speed during the evening, when networks are busiest, and keep the provider's support number with your other important numbers. Our article on working as a digital nomad in Thailand and our guide to coworking in Chiang Mai and Bangkok describe the wider setup.
Backups: power cuts and mobile data
A fibre line stops when the electricity stops, because the router and the fibre box need power. Short cuts happen in storms; our guide to power cuts in Thailand explains planned outages and how to find them. A small uninterruptible power supply (UPS) or a power bank that can run the router keeps you online through a short cut, as long as the provider's network is still up.
Keep a mobile data plan as the second line. A Thai SIM with a generous data allowance, used as a phone hotspot, covers most outages and the days between moving out and the new line being installed. If you need two independent connections for work, choose a mobile network that is different from your fibre provider.
Moving out or leaving Thailand
Give notice the way the contract requires, return all lent equipment and get a receipt, and pay the final bill. If you leave before the minimum period ends, ask what cancelling early will cost. Bills left unpaid can follow your account, and the next tenant may find the line still registered in your name, so close it properly rather than simply leaving.
Frequently asked questions
Can a foreigner get home internet in Thailand?
Yes, foreign residents can sign a fibre contract with a Thai provider. Bring your passport with your visa, and ask the provider before you apply which other documents it wants, such as a lease or work permit, because we found no official list that applies to all of them.
How much does fibre internet cost in Thailand?
As one example, AIS Fibre listed packages from 499 baht a month for 300/300 Mbps on a 12-month contract on 19 October 2026, up to 1,200 baht for 1 Gbps both ways. Ask whether VAT is included and what the price becomes after any promotion.
Is 3BB now part of AIS?
Yes. AIS acquired Triple T Broadband, the company behind 3BB, and 3BB's website now offers AIS packages. If you have an older 3BB contract, ask the provider how it is affected before you change plan or move.
What happens to my internet contract if I move?
Ask before you sign. Some providers can move the line to a new address for a fee; otherwise, ask what it costs to cancel before the minimum contract period ends. Return the router and any other equipment, and keep the receipt.
