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.

  • Best value for lighter, shorter trips
  • Clear allowance — pay only for what you need
  • Top up any time from your phone

Your guide to Chiang Mai

Chiang Mai eSIM: your local data guide.

Chiang Mai rewards wanderers, from the temple-dotted Old City to the mountain road up Doi Suthep. A Chiang Mai eSIM keeps Grab, maps and Google Translate handy as you browse the Sunday Walking Street, book an ethical elephant sanctuary in the hills, or find a flat white among Nimman's coffee roasters. Set it up before you fly and land connected.

One eSIM for Chiang Mai and all of Thailand. It's the national Thailand eSIM — from $3.14/day with unlimited data, working the same in Chiang Mai as it does the moment you leave it.
Landing at Chiang Mai International Airport (CNX)?

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 Chiang Mai.

Old City (Tha Phae Gate)

Dropped pins guide you between Wat Chedi Luang, Tha Phae Gate and dozens of temples tucked inside the ancient moat.

Nimmanhaemin (Nimman)

Café reviews, co-working maps and QR payments all lean on a steady connection in this trendy, nomad-friendly district.

Doi Suthep

Navigate the switchback mountain road and share golden-temple views, though signal thins near the very summit.

Sunday Walking Street

Translation and QR-code payments help you haggle for handicrafts along Ratchadamnoen Road each week.

The practical bit

Getting around Chiang Mai on your eSIM.

Apps you'll want online in Chiang Mai
  • GrabRide-hailing in a city where red songthaew trucks are the only other easy option.
  • BoltCheaper rides, popular with Nimman's large digital-nomad and long-stay crowd.
  • Google MapsNavigates the switchback road up Doi Suthep and pins temples across the Old City moat.
  • 12Go AsiaBooks minivans, buses and the sleeper train onward to Pai, Chiang Rai and Bangkok.
How long to stay in Chiang Mai

Most people give Chiang Mai three to five nights, covering the Old City temples, a night market, an ethical elephant sanctuary and a day trip up into the hills.

How much data for Chiang Mai

City 4G is quick and Nimman runs on café Wi-Fi, so light users manage on around 1GB; remote workers and heavy streamers should size up to 5GB or Unlimited for daily video calls.

Coverage in Chiang Mai

Chiang Mai's centre, Nimman and airport enjoy solid 4G and growing 5G, but signal thins on the forested climb to Doi Suthep's summit and fades fast on mountain roads toward Doi Inthanon and Pai.

What is a Chiang Mai eSIM?

A Chiang Mai eSIM is a digital SIM that's already built into your phone. Scan one QR code and a local Chiang Mai data plan installs alongside your home SIM — no plastic, no tray tool, no swap. Your number and WhatsApp stay exactly where they are.

Peace of mind

Your Chiang Mai eSIM: data-only, zero bill shock.

Your Chiang Mai eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Chiang Mai, 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.

Traveller relaxed and connected on her phone, no roaming bill to worry about

Chiang Mai eSIM questions, answered.

Yes, for most of the climb and at Wat Phra That Doi Suthep itself you'll have usable data for maps, photos and songthaew fares. Signal can weaken on the highest, most forested stretches, so cache your directions before you set off.
