Internet & SIM cards in Phang Nga.

AIS Fibre is Thailand's largest fibre provider and the most reliable home-internet choice across Phang Nga -- independently confirmed via AIS's own coverage listings for Phang Nga town and for Ko Yao (Ko Yao Noi/Ko Yao Yai), with plans advertised from around 269 baht a month. Coverage is strongest in Phang Nga town and the Khao Lak beach strip; check AIS's own online coverage checker for a specific address before committing to a lease.

True (now merged with dtac) is the other national giant, offering True Online fibre often bundled with TrueVisions TV and mobile SIM discounts. It is available along the Khao Lak resort strip and in Phang Nga town, with pricing broadly comparable to AIS -- roughly 400-900 baht a month depending on speed. Bundle promotions vary by building, so compare the exact package on offer for your specific condo or house.

3BB (now under the AIS/3BB umbrella) is the budget-friendly, no-frills fibre option in Thailand, often undercutting the big two where it reaches. Availability in Phang Nga is patchier than AIS or True -- it's worth asking your landlord or building manager which providers are already wired in before assuming 3BB reaches your specific address.

AIS Fibre is confirmed available on Ko Yao (both Ko Yao Noi and Ko Yao Yai), so a proper wired connection is realistic there if you're basing yourself on the islands rather than the mainland. The Similan Islands are a different story entirely -- a seasonal national park (open roughly November to May) reachable only by boat, with no permanent population and no fixed infrastructure, so treat any stay there as fully mobile-dependent, and expect gaps even on mobile data away from the ranger station.

In Phang Nga town and along the Khao Lak strip, homes already wired for fibre can usually get connected within a few days of booking -- you pick a plan, book an appointment, and a technician installs a router. Homes off the main grid, including many Ko Yao Noi properties, may need a fresh line pulled, which takes longer. You'll typically need your passport and lease; some plans require a 12-month contract while others run month-to-month at a slightly higher rate. Many furnished long-stay rentals already include fibre in the rent, so ask your landlord first.

Thailand's mobile market is now effectively AIS versus True Corporation (True completed its merger with dtac, so they operate as one network under two brand names). AIS holds the largest market share nationally and consistently shows stronger rural and island coverage -- the safer default if you'll spend time on Ko Yao Noi, Ko Yao Yai, boat tours through Phang Nga Bay, or the Similan Islands. In Phang Nga town and the Khao Lak strip both networks deliver solid 4G/5G, so there the choice comes down to price and the nearest shop.

Prepaid (top-up) SIMs are the easy starting point: buy one over the counter with your passport, add credit, and pick a data package -- no contract, no credit check. Postpaid (monthly bill) plans can be cheaper per gigabyte for heavy users and give you a fixed number, but require more paperwork -- typically a passport plus proof of address or a long-stay visa, and sometimes a deposit for foreigners. Most expats in Phang Nga start on prepaid and move to postpaid once settled with a lease and address.

Tourist SIM packages -- typically 8, 15 or 30 days of generous or unlimited data for a few hundred baht -- are convenient for a short Khao Lak beach holiday but poor value over months. For a long stay, buy a standard prepaid SIM from an operator shop or convenience store and attach a monthly data package, which works out far cheaper than repeatedly renewing tourist bundles.

Both AIS and True support eSIM on compatible phones, activated in-store by scanning a QR code -- handy if your phone lacks a spare physical slot. International travel eSIM providers (Airalo, Holafly and similar) let you land already connected via Phuket International Airport (the nearest major gateway to Phang Nga), though for a long stay a local physical or eSIM plan from a Thai operator works out cheaper. Confirm your phone model supports eSIM before relying on it.

Phang Nga town and the Khao Lak strip have solid connectivity for remote work: 4G is fast and near-universal, AIS Fibre and True Online comfortably handle video calls and uploads, and 5G is expanding along the main roads. The picture changes heading out to Ko Yao Noi and Ko Yao Yai (fibre exists but is patchier) and drops to mobile-only, intermittent signal on the Similan Islands. The practical setup for remote work is a fibre plan in Phang Nga town or Khao Lak plus a strong AIS mobile data package as backup.

Topping up a prepaid SIM is straightforward: use the operator's app (myAIS or TrueiD), buy a top-up voucher at any 7-Eleven or Family Mart -- both common in Phang Nga town and along the Khao Lak strip -- use a top-up kiosk, or dial the USSD code on your SIM starter pack. Once you have credit, activate a data package through the app or a short code; the apps also let you check balance, buy add-ons and set auto-renew.

The nearest airport is Phuket International Airport (about 1-1.5 hours from Khao Lak), where you can buy a SIM on arrival, though tourist bundles there run pricier. Official AIS and True shops in Phang Nga town and along the Khao Lak strip are the best one-stop option for postpaid, eSIM setup and English-speaking help; any 7-Eleven or convenience store sells basic prepaid SIMs. Thai law requires SIM registration, so always bring your passport.

Expect roughly 269-900 baht a month for home fibre depending on provider and speed (AIS Fibre's entry plans start from around 269 baht), and 300-600 baht a month for a solid mobile data package. A basic prepaid starter SIM costs around 50-200 baht before you add data. All in, a well-connected household in Phang Nga typically spends about 600-1,300 baht a month on internet and mobile combined.

AIS Fibre has the broadest confirmed presence across Phang Nga town, the Khao Lak strip and even Ko Yao (Ko Yao Noi/Ko Yao Yai), with entry plans advertised from around 269 baht a month. True Online is a solid alternative, often bundled with TV. 3BB reaches less of the province. Always confirm which providers serve your exact address before signing a lease.

Ko Yao Noi and Ko Yao Yai have confirmed AIS Fibre availability, so a proper wired connection is realistic if you're island-based. The Similan Islands are a seasonal national park (open roughly November-May), boat-access only with no permanent population -- treat any stay there as mobile-only, and expect gaps even on mobile data away from the ranger station.

Most expats in Phang Nga start with a prepaid (top-up) SIM -- buy it over the counter with just your passport, no contract or credit check -- and add a monthly data package. Postpaid plans can be cheaper per gigabyte for heavy users but need proof of address or a long-stay visa, and sometimes a deposit for foreigners.

AIS has the larger network and the stronger track record on islands, boats and rural roads -- the safer default if you'll spend time on Ko Yao Noi, Ko Yao Yai, or touring Phang Nga Bay by boat. In Phang Nga town and along Khao Lak, both AIS and True (now merged with dtac) deliver fast, reliable 4G, so price and the nearest shop matter more there.

Budget roughly 269-900 baht a month for home fibre depending on provider and speed, and 300-600 baht for a good mobile data package. A basic prepaid starter SIM is about 50-200 baht before data. Combined, a connected household typically spends around 600-1,300 baht a month on internet and mobile.
