Frequently asked questions

Can I use eSIM Chiang Mai in other cities across Thailand?

Yes, eSIM Chiang Mai works not only in Chiang Mai but also 99% of the time in Thailand. City eSIM Plans help you connect to the best network in the selected city.
If you plan to stay longer in a particular city, consider choosing our City eSIM Plans for added convenience.

Should I order and activate an eSIM before traveling?

You can purchase an eSIM at your convenience before your travel date, but remember that your data plan will start as soon as you have installed the eSIM on your device.
Additionally, please note that to install the eSIM, your device must be connected to a Wi-Fi or a cellular data network.

Are voice calls and SMS available with the eSIM plan?

You can make phone calls with eSIM Chiang Mai, but the included call credit is limited. You will receive a local mobile number through your eSIM QR Code email after purchase. eSIM Chiang Mai provides 15 minutes of free call credit, and unlimited calls among Dtac numbers.

After my eSIM data amount runs out, can I make a top-up?

Please note that we do not offer a top-up service for eSIM Chiang Mai. Instead, we recommend purchasing a new eSIM plan and installing it on your device again.

Easy setup and value for money

Network coverage is good throughout the city, even at mountainous area. Setting it up was pretty easy as there is a guide provided after purchase. Would definitely get another for my next trip.

Works as advertised; A smooth, seamless experience!

It’s my first time in Thailand; so I wasn’t entirely sure what to expect. I scanned the QR Code while still in my home country; and when I landed in Chiang Mai, my phone automatically connected to the local telco. I got 5G speeds in the city and 4G speeds in the mountains; save for a couple of no-signal zones. The local telco’s app worked and displayed my remaining data package. Really happy with this service and the reasonable price paid. Will definitely order an E-sim again the next time I’m back here. Thank you!
