Internet & SIM cards in Phuket.

AIS has the broadest fibre footprint on the island and is the default choice for many long-stay renters, reaching most condos and villa estates from Patong to Bang Tao. Packages typically run from around 500-700 THB/month for entry speeds up to roughly 1,000-1,200 THB for the faster 1Gbps tiers, and its English-friendly myAIS app makes billing and top-ups easy.

True is the other big fibre player in Phuket and is strong in the built-up west-coast and town areas, often bundling internet with TrueVisions TV and mobile lines. Pricing is broadly similar to AIS - roughly 500-1,200 THB/month depending on speed - and it is a common pre-installed option in newer condo buildings.

3BB (now under the National Telecom / AIS umbrella) is popular for value, with keen pricing on mid-tier speeds and a solid reputation among expats in residential areas. It is worth quoting alongside AIS and True; in some estates it is the cheapest route to a reliable 300-500 Mbps line.

NT, the merged state operator (former TOT/CAT), still provides fibre in parts of the island, including some areas the private ISPs reach less densely. Service and English support can be more variable, but it is a useful fallback where AIS, True and 3BB coverage is thin.

AIS has the strongest overall mobile network in Phuket and the most reliable data across the island, including the beaches and viewpoints. It is the safest single-SIM choice for anyone who depends on their connection, with well-stocked shops in every mall and at the airport.

True and dtac have merged into a single operator, giving True a large, improved network that competes closely with AIS in the populated west-coast and town areas. Coverage is excellent where people live and work; AIS still edges it in the most remote corners of the island.

Both AIS and True sell tourist SIMs at Phuket International Airport and in convenience stores, bundling generous data (often unlimited at capped speed) for 8-30 days from a few hundred baht. They are the fastest way to get online the moment you land, before deciding on a longer-term plan.

Most newcomers start on prepaid (pay-as-you-go, top up in any 7-Eleven or via the app) because it needs no contract. Once you have a lease and ideally a work permit or long-stay visa, a postpaid monthly plan can be cheaper for heavy users and adds perks - but prepaid is perfectly adequate for most long-stay renters.

AIS, True and travel-eSIM providers (Airalo, Holafly and others) all support eSIM on compatible phones, letting you activate a Thai data plan before you even arrive. It is ideal as a backup line or for travellers who island-hop, though a physical local SIM is still cheapest for a settled long stay.

The busy west-coast strip from Patong through Karon and Kata has the densest fibre and mobile coverage on the island - multiple ISPs reach most buildings and 4G/5G is strong. If uninterrupted connectivity matters, the developed west coast is the safest bet.

The southern long-stay belt around Rawai, Nai Harn and Chalong is well covered by AIS and True fibre and popular with remote workers, though a few villa pockets up in the hills can see slower speeds. Check the specific address before signing a lease if your income depends on your line.

The affluent northwest around Bang Tao, Laguna, Cherng Talay and Surin has good modern fibre in the branded estates and condos, with reliable mobile data. Some newer developments come internet-ready, so ask whether a line is already installed before ordering your own.

Phuket Town and the central districts get city-grade fibre and the fullest choice of providers, usually the quickest to install. Coverage thins only in the rural hills and far-flung capes, where NT or a mobile 5G router can fill gaps that fixed fibre does not reach.

For digital nomads and DTV holders, Phuket is a dependable base: fibre in the main areas comfortably handles video calls and large uploads, and a cheap second SIM on a different network is the standard insurance against outages. Coworking spaces in Rawai and Bang Tao also offer business-grade backup connections.

Thai law requires SIM cards to be registered to a passport, so bring yours when you buy - shops and airport counters register it on the spot in minutes. eSIMs are registered digitally during activation. Keep your number active with an occasional top-up so a long-unused prepaid line is not recycled.

Typical home fibre in Phuket runs from 300 Mbps up to 1Gbps, more than enough for streaming and remote work, while mobile 5G in the towns can be very fast. Real-world speed depends on your building's wiring and the estate's backhaul, so a quick speed test during a viewing is worth doing.

Prepaid top-ups are effortless - any 7-Eleven, Family Mart, the carrier apps or PromptPay QR - while home fibre is billed monthly and easily paid through banking apps or at convenience stores. Setting up auto-pay from a Thai bank account once you have one keeps the line uninterrupted.

AIS has the strongest and most reliable network across the whole island, including the beaches and viewpoints, so it is the safest single-SIM choice. True (now merged with dtac) is very close in the populated west-coast and town areas. Many long-stay residents carry an AIS line plus a cheap second SIM on True as a backup.

Home fibre from AIS, True or 3BB typically runs from around 500-700 THB per month for entry-level speeds up to roughly 1,000-1,200 THB for 1Gbps plans. 3BB is often the cheapest for mid-tier speeds. Some newer condos and villa estates come with a line already installed, so ask before ordering your own.

Yes. AIS and True both have counters at Phuket International Airport (HKT) selling tourist SIMs with generous data for 8-30 days, and they register the SIM to your passport on the spot. It is the fastest way to be online the moment you land before choosing a longer-term prepaid or postpaid plan.

Yes - fibre in the main areas (Patong and the west coast, Rawai, Bang Tao and Phuket Town) comfortably handles video calls and large uploads, and mobile 5G is fast in the towns. The usual advice is to confirm the specific building's line during a viewing and keep a second SIM on a different network as backup.

Yes. Thai law requires every SIM to be registered to an identity document, so bring your passport when buying a physical SIM - registration takes a few minutes in any carrier shop, convenience store or airport counter. eSIMs are registered digitally during activation.
