Will I get signal on Ko Larn?

Around Na Baan pier and Tawaen Beach you'll have usable 4G for photos and messaging. It grows patchier on the island's remote coves, so screenshot ferry times and your return-boat details in advance.

Can I use ride-hailing apps in Pattaya?

Yes - Grab and Bolt both operate here and need a live connection to book and track cars. Data also helps you compare fares against the local baht-buses, which don't use meters or apps.

Good to know in Chonburi

Pattaya's baht-bus (songthaew) routes aren't in most map apps, so keep data on to cross-check directions - and download a Ko Larn ferry schedule, as the island's signal drops on the western beaches.

Best time to visit Chonburi

November to February brings dry, cooler weather ideal for Pattaya's beaches; March to May turns hot and humid before the rains.

Two simple ways to buy

Chonburi eSIM plans: unlimited, or by the GB.

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

Chonburi eSIM: your local data guide.

Chonburi packs Thailand's eastern seaboard into one province - the buzz of Pattaya, the seafood markets of Si Racha, student-favourite Bang Saen beach and the day-trip island of Ko Larn. Whether you're booking a speedboat, navigating Sukhumvit-Pattaya traffic or finding a rooftop bar, a Chonburi eSIM keeps maps, Grab and messaging live.

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

Landing at U-Tapao Pattaya (UTP), with Bangkok Suvarnabhumi (BKK) a common alternative?

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

Across the region

Where you'll lean on data in Chonburi.

Pattaya

Dense 4G/5G across Beach Road and Jomtien means ride-hailing, bar-hopping and hotel bookings all run smoothly.

Ko Larn (Coral Island)

The main pier and Tawaen Beach have decent signal, but it weakens on the quieter far-side coves.

Si Racha

This industrial port town has strong, steady coverage - useful for expat services and seafood-market navigation.

Bang Saen

Chonburi's local beach resort stays well connected along the promenade, ideal for weekend crowds and food stalls.
