Is there any data at the Similan Islands?

Realistically no. The Similans are remote national-park islands with essentially no mobile network, and they close during the monsoon. Plan for a full digital detox and sort bookings and directions on the mainland first.

Is Phang Nga's eSIM the same as Phuket's?

Yes - it's the single national Thailand plan, so one eSIM covers Phuket airport, the drive north and all of Phang Nga, roaming onto AIS, TrueMove H or dtac as you go.

Good to know in Phang Nga

The Similan Islands sit beyond mobile coverage and only open from around mid-October to mid-May, so treat any liveaboard trip as fully offline and download maps, tickets and playlists before you sail from Khao Lak.

Best time to visit Phang Nga

November to April is prime - calm Andaman seas, and the Similan Islands only open for diving during these dry-season months.

Two simple ways to buy

Phang Nga eSIM plans: unlimited, or by the GB.

Every Phang Nga eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Phang Nga — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Phang Nga eSIM: your local data guide.

Phang Nga is the Andaman's scenery-stealer - the towering limestone stacks of Phang Nga Bay, James Bond Island near Ko Panyi's floating village, the beach resorts of Khao Lak and liveaboard boats out to the Similan Islands. A Phang Nga eSIM helps you book kayaking tours, check dive-season conditions and navigate between piers.

One eSIM for Phang Nga and all of Thailand. It's the national Thailand eSIM — from $3.14/day with unlimited data, working the same in Phang Nga as it does the moment you leave it.

Across the region

Where you'll lean on data in Phang Nga.

Khao Lak

The main resort strip and Bang Niang market have solid 4G/5G for tours, dining and dive bookings.

Phang Nga Bay

Signal is intermittent among the karst islands, so download maps and tour details before your longtail leaves the pier.

Ko Yao Noi

This laid-back island has workable coverage around the villages, thinning on its quieter eastern shore.

Similan Islands

Expect little to no signal on these remote dive islands - a genuine offline stretch, so prepare beforehand.

The practical bit

Getting around Phang Nga on your eSIM.

Apps you'll want online in Phang Nga

Grab— Main ride-hailing and food app; works in Khao Lak and for airport transfers from Phuket.
12Go Asia— Books ferries, minivans and speedboats linking Phuket, Khao Lak and the Ko Yao islands.
Klook— Popular activity app for booking Similan day trips, Phang Nga Bay kayaking and canopy tours.
Bolt— Alternative ride-hailing app, mainly useful around Phuket airport and the transfer routes.

How long to stay in Phang Nga

Many treat Phang Nga as two to four days around Khao Lak, or add a multi-day liveaboard to the Similan Islands for divers.

How much data for Phang Nga

Light-to-balanced 1-3 GB covers most Khao Lak stays, since much of your island and dive time is offline anyway. Add more only if you'll stream at your resort each evening.

Coverage in Phang Nga

Khao Lak and the mainland resorts get strong 4G/5G, but signal thins fast across Phang Nga Bay's karsts and disappears almost entirely at the remote Similan Islands.
