Internet Providers in Thailand — True vs AIS vs 3BB 2026

All three major providers cover Bangkok, Chiang Mai, Phuket, Pattaya, Hua Hin, Khon Kaen, and Udon Thani comprehensively. In smaller towns and rural areas, AIS Fibre tends to be the most aggressive in expansion and is often the only fibre option in newer condominium projects. 3BB has historically been strong in provincial Thailand outside Bangkok. True Online's footprint in central Bangkok is unmatched but its rural reach is more limited. On Koh Samui, Koh Phangan, and Koh Tao, AIS Fibre is the dominant residential provider. The Koh Tao network is notoriously variable regardless of provider.

Entry-level fibre at 300 Mbps symmetric runs 400–600 THB/month across all three providers. The sweet-spot 500–1000 Mbps plan costs 700–950 THB/month. True Gigatex 2000/2000 Mbps and AIS Fibre 2000/2000 hit around 1,200–1,500 THB/month including 4K TV box. Promotional pricing often gives 6 months at 50% off then jumps to standard rate; read the contract end. Add 7% VAT on top of headline price. Activation fees of 1,500–3,500 THB are sometimes waived. Standard contract is 12 months with substantial early-termination fees; AIS and True both offer no-contract plans at 100–200 THB/month premium.

True is the largest fixed-broadband provider in Thailand by subscribers and dominates Bangkok central. The fibre is generally fast and stable. The downside is True's notorious customer service: long hold times in English, billing errors that take weeks to resolve, and contract conditions that pull customers into bundled mobile/TV plans they don't need. The True iD TV bundle is heavily pushed. The True app and online portal are functional but not great. Verdict: best fibre quality in Bangkok central, but the worst customer support of the three when something goes wrong.

AIS is the strongest mobile network in Thailand and has built a credible fibre service over the last decade. Reliability is generally excellent. The AIS PLAY TV bundle includes BeIN sport channels that are popular with expats. Customer service has English-speaking staff at the central call centre and is the most foreigner-friendly of the three. AIS Fibre's mesh wifi router (the Huawei H66 unit) is solid for typical 1–2 bedroom apartments. Verdict: the best default choice for foreigners in 2026 — good network, good service, easy contract.

3BB is owned by JASMINE and now under the same corporate umbrella as AIS following acquisition. It historically focused on provincial Thailand and the strategy was lower prices than True or AIS. Network performance is competitive but the customer service has been the weakest of the three for English-speaking customers, with most agents not speaking English. The 3BB app is in Thai only. If your landlord installed 3BB and the connection works, leave it. If you're choosing a new provider, AIS or True are generally better choices for English-speaking customers.

Many expats keep an AIS or True mobile SIM with a 4G/5G unlimited data plan as backup. AIS 5G in Bangkok averages 500–700 Mbps download in good coverage areas and works reliably as a primary internet during fibre outages. A 599 THB/month unlimited plan plus a Huawei E5577 mobile hotspot router gives full home backup for under 800 THB total. For digital nomads, an unlimited mobile plan alone is often sufficient — many Bangkok and Chiang Mai apartments now don't bother with fibre.

Installation requires a Thai phone number for verification, a copy of your lease, and either a Thai ID or a passport. Some providers require a landlord signature. Installation typically takes 3–7 days from order to engineer arrival; faster in central Bangkok, slower in smaller cities. The engineer brings the router and runs fibre to a wall plate. Initial setup is usually completed in 60–90 minutes.
