eSIM for Chiang Mai
Your days start when you land, not when you pay
- Installs in minutes
- Keep your number
- Share data with other devices (hotspot)
- No roaming fees
- Secure payment with Stripe
Chiang Mai is where a lot of long-stay travel actually happens: months rather than days, a café as an office, a scooter instead of taxis. That makes connectivity less a holiday convenience and more the thing the working week runs on.
Most days it is a hotspot for a laptop, calls across awkward time zones, and maps on day trips into the hills or up to Pai. If you are staying a while, topping up matters more than the first plan — you can add data without changing the eSIM.
This is an eSIM for Thailand. It works everywhere in the country, Chiang Mai included — there is no Chiang Mai-only plan, and you would not want one. See all Thailand plans

FAQs for your travel eSIM
Is this eSIM only for Chiang Mai?
No. It is an eSIM for Thailand, and it works across the whole country, Chiang Mai included. That is deliberate: plans are sold per country, so you stay connected when you leave Chiang Mai instead of losing data at the edge of town.
Will my phone work with the Chiang Mai eSIM?
Any eSIM-compatible phone bought in the last few years (iPhone XS or newer, Pixel 3 or newer, recent Samsung Galaxy, etc.) works with our Chiang Mai travel eSIM. Use our compatibility checker if you are unsure.
When does the Chiang Mai eSIM start counting?
Validity starts the moment your travel eSIM connects to a network in Chiang Mai, not when you buy it. You can install it before your trip without losing days.
Do I keep my regular number while using the Chiang Mai eSIM?
Yes. Your physical SIM stays active for calls and SMS on your normal number. The Chiang Mai eSIM only handles mobile data, so WhatsApp, maps and apps all run on your eSIM data.
Can I tether or use a hotspot in Chiang Mai?
Yes, every Chiang Mai eSIM plan allows tethering and personal hotspot, so you can share your eSIM data with a laptop or another device.
What happens if I run out of eSIM data in Chiang Mai?
Top it up from your account: open the eSIM and tap Top up. The extra data is added to the same eSIM — no new QR to scan and no shop to visit. If your plan doesn't support top-ups or has already expired, buy a new Chiang Mai plan instead.
Is the Chiang Mai eSIM refundable?
If you haven't installed your eSIM (installing means scanning the QR) or activated it, and the plan hasn't expired, we refund it in full: contact support with your order number. Once it is installed or activated it can't be refunded because you changed your mind — but if it isn't working, contact us and we'll sort it out.
