Does the eSIM work on the boat over to Koh Larn?

You'll have a solid signal at Bali Hai Pier and around Koh Larn's main beaches like Tawaen, but data drops on the short open-water crossing. Pin your beach and return ferry time before boarding to stay on track.

How much data will I need for a Pattaya break?

For maps, Grab, messaging and photos, most visitors use around 500MB to 1GB a day. Add more if you stream or share lots of video, and remember the same plan covers your Bangkok arrival and transfer too.

Good to know in Pattaya

Most visitors reach Pattaya not by its small U-Tapao airport but by a roughly two-hour drive from Bangkok's Suvarnabhumi, so keep your eSIM active on the transfer to follow the route and message your hotel.

Two simple ways to buy

Pattaya eSIM plans: unlimited, or by the GB.

Every Pattaya eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Pattaya — 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.

Plan your data

How much data do you need in Pattaya?

A rough, honest guide to sizing your Pattaya eSIM so you're not guessing. Most travellers in Pattaya are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Pattaya eSIM: your local data guide.

Pattaya packs a buzzing beachfront, day-trip islands and the giant Sanctuary of Truth into one easy-reach resort city near Bangkok. A Pattaya eSIM keeps Grab, maps and boat bookings running as you stroll Beach Road, catch a speedboat to Koh Larn, or find dinner off neon-lit Walking Street. Install before you fly and you'll be online the moment you arrive.

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

Landing at U-Tapao–Pattaya International Airport (UTP); most fly via Bangkok Suvarnabhumi (BKK)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

On the ground

Where you'll lean on data in Pattaya.

Jomtien Beach

Quieter than the centre, where maps and ride-hailing help you find beachfront cafés and book water-sports slots.

Walking Street

Translation and Grab keep you oriented and safely on your way home through the crowded neon nightlife strip.

Koh Larn (Coral Island)

Strong signal at Bali Hai Pier fades on the crossing, so pin your beach and return ferry before you sail.

Sanctuary of Truth

Map the seafront route and capture the all-teak carved temple, sharing photos on a steady city connection.

The practical bit

Getting around Pattaya on your eSIM.

Apps you'll want online in Pattaya

Grab— Ride-hailing beyond the fixed-route baht-bus songthaews looping Beach and Second Roads.
Bolt— A cheaper ride-hailing option for late nights around Walking Street and Jomtien.
12Go Asia— Books buses and vans from Bangkok plus the Koh Larn ferry from Bali Hai Pier.
Google Maps— Maps the seafront route out to the Sanctuary of Truth and Jomtien's cafés.

How long to stay in Pattaya

Pattaya is often a two-to-four-night break or an easy weekend from Bangkok, enough for the beaches, a Koh Larn day trip and the Sanctuary of Truth.

How much data for Pattaya

For maps, Grab, messaging and photos most visitors use 500MB to 1GB a day, so a balanced 3-5GB covers a short break; add Unlimited if you stream or share plenty of video.

Coverage in Pattaya

Pattaya, Jomtien and the Sukhumvit approach from Bangkok all have strong 4G and 5G, but signal drops on the short open-water crossing to Koh Larn before returning around the island's main beaches.

Peace of mind

Your Pattaya eSIM: data-only, zero bill shock.

Your Pattaya eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Pattaya, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.

Pattaya eSIM questions, answered.

Most travellers fly into Bangkok's Suvarnabhumi (BKK), then drive around two hours to Pattaya; a few regional flights use U-Tapao (UTP). The eSIM connects at either airport the moment you land, so you're online for the whole transfer.
