Thailand eSIM FAQs
Your eSIM will activate automatically once you arrive in Thailand. We advise installing your Thailand Travel eSIM before you travel (installation is distinct from activation).
To install, just scan the QR code we send or install via the ZenSim app over WiFi. On landing in Thailand, the eSIM will switch on by itself.
If you have any problems, check our eSIM Troubleshooting Guide or contact us 😊
Your Thailand eSIM will start working the moment you land in Thailand-it auto-activates if installed prior to departure.
If you install it after arrival, it will connect immediately.
Trouble connecting? Visit our eSIM Troubleshooting Guide or contact us for help.
No, our Thailand travel eSIMs do not include any phone number - they strictly provide internet data. For calls, use data - driven apps such as WhatsApp, Signal, or Facetime.
No, our Thailand eSIMs only deliver mobile data. For voice or SMS, you’ll need to use an app that works over data - WhatsApp, Skype, or other similar internet calling platforms.
Signal & Connectivity: If you’re stuck without data, follow our detailed troubleshooting guide. If issues persist, contact support and we’ll fix it promptly.
Install Assistance: For help installing, consult our installation walkthrough. Still need help? Reach out and we’ll guide you step by step.
Other Support Requests: For anything else, head to our contact page.
Definitely! ZenSim supports eSIM usage in over 200 countries, so Thailand is covered. If you need multi-country coverage, take a look at our regional eSIM options on the Travel eSIMs page.
Not until you land in Thailand. Installing ahead won’t start your plan; it goes live automatically when you arrive.
Make sure to install before you travel, as WiFi is required for setup and this way your Thailand eSIM will be ready to use when you land.
If you encounter connection issues, see our eSIM Troubleshooting Guide or contact support.
Most ZenSim eSIMs can be topped up directly inside the app. If you ever need extra data, additional days, or want to include a new destination on the same eSIM, the Zen Garden is where you can do it.
Simply log in, tap into the Zen Garden, and you’ll find the option to top up right there.
Available top ups: For Thailand, the top up plans are identical to the ones on the site, but you get a 10% discount.
Extending your stay: Planning to be away longer than 30 days? You can buy multiple top ups ahead of time. They activate one after another, so there’s no risk of replacing your current plan.
More than one country: Many eSIMs now let you attach extra countries through a top up. For example, while using a Europe eSIM you can add Singapore as an extra destination. It will activate automatically when you land in Singapore.
Yes! You may install the Thailand eSIM up to 30 days before you travel. It won’t connect or start using data until you arrive.
Early installation ensures you’re ready on arrival, and it won’t drain your plan until you’re in Thailand.
If you encounter an activation message on iPhone before landing, it’s usually safe to ignore - see our eSIM Troubleshooting Guide for more info.
If you want to avoid roaming headaches in Thailand, a travel eSIM is the smarter pick:
Big Savings: Our local Thailand eSIM data plans are priced for residents, not tourists who pay premium roaming costs.
Easy Plan Changes: Upgrade or downgrade your data allowance on the fly - no need for a new SIM.
Full Transparency: See your data usage in - app so you won’t run out unexpectedly or incur extra charges.
Single-country eSIMs like the Thailand one are only valid within that country once activated.
For travel across borders, a regional plan might suit you better - our regional Travel eSIMs cover multiple countries in one.
