eSIM Chiang Mai 
Can I receive verification codes (OTP) on a voice eSIM?
Yes. Incoming SMS reaches your voice eSIM from anywhere in the world and is free, so one-time codes from banks, WhatsApp, Google or Telegram do arrive - on a French number, since that is where the number is issued. There is one important limit, and we would rather you hear it from us than discover it later: the number changes roughly every 30 days. That makes it fine for a code you need while you are travelling, but wrong as the permanent number on your account. If you register it for two-factor authentication or move your WhatsApp to it, you can lose access to that account once the number changes. Keep your own number for anything you need long term.
Can I install multiple eSIMs on the same phone?
Yes. Modern iPhones and Android devices support multiple eSIM profiles - typically 5 to 8 stored profiles, with 1 or 2 active simultaneously. You can install eSIMs for different countries and switch between them in settings without removing any.
How can I verify if my eSIM is activated?
There are two clear indicators: (1) your phone's status bar shows the local carrier name once you arrive at your destination, and (2) the data icon (4G, LTE, or 5G) appears next to the eSIMno line in your cellular settings. If neither shows up, turn airplane mode on and then off again, or restart your phone.
Do I need to remove my eSIM after my trip?
You don't have to remove it. When your plan ends, the eSIM stops providing data and moves to Archived in Profile > My eSIMs. If you keep it installed on your phone, you can top it up there and use it again - no new QR code needed (top-ups aren't available for unlimited and voice plans). If you need the space, you can delete the old profile in your phone's cellular settings; after that, you'll need a new eSIM for your next trip.
How do I set up the eSIM on my device?
The fastest way is straight from your order confirmation email, which now contains - for each eSIM - the QR code, a one-tap install link, and the SM-DP+ / activation codes. On the phone you'll use, tap the one-tap install link; or, to use the QR, show it on another screen or a printout and scan it with that same phone (not another phone); or enter the codes manually. The email also has an "Install eSIM" button that opens your eSIM's detail page and launches the install pop-up (sign in if prompted), and you can reach the same pop-up anytime via Profile > My eSIMs > find your plan (shown as "Ready to use") > Install. After installing, turn Data Roaming ON for your eSIMno line (iPhone: Settings > Cellular; Android: Settings > Connections/Network) - without it the eSIM installs but shows no internet.

Can I tether or use Personal Hotspot with my eSIM?
Yes. Your eSIMno plan supports tethering and Personal Hotspot at no extra charge. Activate the Personal Hotspot feature in your device settings and connect other devices as you would with any cellular plan. Data used while tethering counts toward your plan allowance.
When should I set up my eSIM?
A Wi-Fi connection is required to install your eSIM, so we recommend setting it up before you leave home. Activation can happen later, either right before departure or after you land at your destination - but the initial QR scan needs Wi-Fi.
Are there any hidden fees or extra charges?
No. The price you see at checkout is the total price - no activation fees, no hidden taxes, no roaming surcharges. Your data plan is fixed-price, and you'll never receive a surprise bill from your home carrier as long as you keep cellular data off on your home SIM.
Can I install my eSIM before traveling?
Yes - setting it up before your trip is the easiest approach. Your confirmation email contains the QR code, a one-tap install link and the manual SM-DP+ / activation codes (the same options are also available via sign in > Profile > My eSIMs > Install). While on Wi-Fi at home, install it with the one-tap link on your phone, or - to use the QR - show it on another screen or a printout and scan it with the phone you are setting up (not another phone). Installing does not start your plan: the validity countdown only begins when the eSIM connects to a mobile network inside your plan's coverage area. While you are outside that area, the eSIMno line and its Data Roaming can stay on - the eSIM cannot connect there, so nothing starts; just keep mobile data on your main line until then. On arrival, set mobile data to the eSIMno line and turn off Data Roaming on your main line so your carrier does not charge roaming fees. Important: if your plan also covers the country you are in right now, turning the line and Data Roaming on starts it immediately - leave both switched off until you want to use it. Please note: once installed, an eSIM is considered used and is no longer eligible for a refund.When Should I Set Up My eSIM?
What data plans are available for the Thailand eSIM?
eSIMno offers data plans from 1 GB up to unlimited data, valid from 1 day to 180 days depending on the plan. Regional and lifetime options are also available for travelers who want flexibility across multiple destinations.
Can I switch the eSIM to a different phone after activation?
Generally no. Once an eSIM is activated on a device, it's tied to that device. If you switch phones, you'll need to install a new eSIM. Some carriers offer eSIM transfer features, but eSIMno plans don't currently support transfer between devices.
Can I use the eSIM on more than one device?
Each eSIM profile is tied to a single device once activated. If you need data on multiple devices (e.g., phone and tablet), you can either purchase separate eSIMs for each device or use the Personal Hotspot feature on your phone to share data with other devices.
