Is there signal at the Golden Triangle border?

Yes, the Sop Ruak viewpoint and Mae Sai town have usable coverage. Take care near the borders, though - your phone may briefly latch onto a Laos or Myanmar network and switch to pricier roaming.

Is Chiang Rai's eSIM different from Chiang Mai's?

No. It's the same national Thailand plan, so one eSIM covers both provinces and the three-hour drive between them, roaming onto AIS, TrueMove H or dtac throughout the north.

Good to know in Chiang Rai

Chiang Rai's best sights are spread across mountain roads with thinning signal and the odd border zone - download offline maps of Doi Tung and Mae Salong, and keep data on to check that day-tour pickups are running.

Best time to visit Chiang Rai

November to February brings cool, clear mountain air and blooming hills; avoid the March-April burning season, when haze blankets the north.

Two simple ways to buy

Chiang Rai eSIM plans: unlimited, or by the GB.

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

How much data do you need in Chiang Rai?

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

Chiang Rai eSIM: your local data guide.

Thailand's northernmost province mixes the surreal - Wat Rong Khun's dazzling White Temple and the cobalt Blue Temple - with mountain country: the Golden Triangle where three borders meet, the tea terraces of Doi Mae Salong and hill-tribe villages around Doi Tung. A Chiang Rai eSIM keeps you routed on winding roads where signposts thin out.

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

Chiang Rai eSIM from $3.14/day — the whole bill, agreed before you fly.

Across the region

Where you'll lean on data in Chiang Rai.

Chiang Rai city

The compact centre and night bazaar have strong 4G/5G for maps, cafes and booking day tours.

White Temple (Wat Rong Khun)

This famous temple just south of the city has solid coverage for photos and ride bookings.

Golden Triangle (Sop Ruak)

Signal is decent at the riverside viewpoint where three countries meet, though it dips on the approach roads.

Doi Mae Salong

Up in the tea hills coverage grows patchy, so download maps before tackling the mountain switchbacks.

The practical bit

Getting around Chiang Rai on your eSIM.

Apps you'll want online in Chiang Rai

Grab— Works in Chiang Rai city for cars and food, though driver numbers thin outside the centre.
Maxim— Ride-hailing app popular in northern Thai towns, often with cars when Grab is scarce.
12Go Asia— Books buses and minivans linking Chiang Rai, Chiang Mai and the Golden Triangle towns.
Klook— Handy for booking White Temple tours, Golden Triangle trips and hill-tribe day excursions.

How long to stay in Chiang Rai

Two to four days suits most, pairing the city's temples with a Golden Triangle run and a day in the tea-growing mountains.

How much data for Chiang Rai

Balanced 3-5 GB works well - you'll lean on maps and navigation more than usual on Chiang Rai's mountain roads. Unlimited suits anyone hotspotting or streaming at their guesthouse.

Coverage in Chiang Rai

Chiang Rai city and the White Temple enjoy strong 4G/5G, but coverage genuinely thins on high mountain roads around Doi Mae Salong, Doi Tung and the remote Phu Chi Fa ridge.
