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 😊
No - the plan’s data and days only start when you arrive in Thailand. Installation beforehand simply sets it up for activation on landing.
We recommend installing before departure since you will need WiFi to complete the installation process and this way you will be connected as soon as you land.
If you need help connecting, check our eSIM Troubleshooting Guide or reach out to us.
Connection Problems: If your Thailand eSIM isn’t loading data, check our troubleshooting post. If that doesn’t do it, contact us and we’ll get you fixed up.
Installation Questions: Need help installing your eSIM? Visit our how-to guide, or shoot us a message at Contact Us and we’ll sort it out.
Anything Else: Got other queries? Visit our contact page and we’ll be right with you.
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.
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.
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.
Of course. Open the ZenSim app and log in. From there, you can choose to top up your eSIM with additional days or gigabytes.
Just select the top-up plan you need (for example, another 30 days or a plan of 10GB) and complete your purchase - it’s instant.
Traditional calls and SMS aren’t part of our Thailand eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.
Once you arrive in Thailand, your eSIM activates automatically if it’s already installed.
If you install it after arriving, the eSIM will activate and begin working immediately.
For any setup or connection problems, refer to our eSIM Troubleshooting Guide or contact our support.
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.

Top 3 Things to Do in Thailand

The Phi Phi Islands are a tropical paradise known for their crystal-clear waters, white sandy beaches, and vibrant marine life.
