eSIM for Chiang Mai
Your days start when you land, not when you pay
- Installs in minutes
- Keep your number
- Hotspot included
- 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

Frequently asked questions
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 eSIMs. Use our compatibility checker if you are unsure.
When does the Chiang Mai eSIM start counting?
Validity starts the moment the 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 keep working.
Can I tether or use a hotspot in Chiang Mai?
Yes, all our Chiang Mai plans allow tethering and personal hotspot, so you can share data with a laptop or another device.
What happens if I run out of data in Chiang Mai?
You can buy a new plan for Chiang Mai at any time and install it on top of the previous one. No need to wait or visit a shop.
Is the Chiang Mai eSIM refundable?
If you have not installed or activated the eSIM yet, contact our support and we will issue a refund. Once the QR has been scanned and the eSIM activated, it cannot be refunded because you changed your mind — but if it isn't working, contact us and we'll sort it out.
