What is an Unlimited Data Plan?

An Unlimited Data Plan provides unlimited data throughout your plan validity. After reaching the daily high-speed data allowance, the connection speed will be reduced, while internet access will remain available for essential online activities.

How is the experience with speed limits on an Unlimited Plan?

After the high-speed data allowance is used, your speed is reduced to 5 Mbps. This is still fast enough for navigation, messaging, browsing, social media, and video calls, so you can stay connected throughout your trip.

Date calculation rules:

All plan time calculations follow a 24-hour cycle. The validity period begins when the plan is activated, and daily data or speed limits reset every 24 hours from the activation time.

How do installation and activation work?

Install and activate your eSIM within 30 days of receiving the QR code. Your plan starts immediately upon activation, and all validity and data cycles are calculated from that time.

Yes! You can keep your primary SIM in your phone while using iRoamly eSIM for data. Simply select iRoamly eSIM for data in your settings to avoid roaming charges.

Some Thailand eSIM plans allow data top-ups. If yours does, you can purchase an add-on directly—no reinstall needed. If not, simply buy a new eSIM and install it as usual.

Yes, iRoamly eSIM supports hotspot and tethering. A few devices may restrict hotspot use due to phone or system limitations, but over 95% of users can share data without issues.

A Thailand eSIM is more convenient: no extra device, no battery to charge, and no need to carry additional equipment. Just install the eSIM and start using mobile data instantly.

The eSIM's validity starts when you enable roaming in your phone settings. To avoid early activation, install the eSIM before departure but do not turn on roaming until you arrive in Thailand.

Most eSIMs allow you to check data usage in the iRoamly app or on our website. For eSIMs that don't support this, contact support@iroamly.com for your balance.

We recommend installing your eSIM a few days before departure while your phone has internet access. Installation at busy airport WiFi may fail. Installing early does not activate your plan until roaming is turned on.

After purchase, your eSIM appears on your iRoamly account and you'll receive an email with the QR code within minutes. If not, check your email address or contact support@iroamly.com.

No. The Thailand eSIM only provides mobile data. Use apps like WhatsApp, Zoom, or Telegram for calls and messages.

  • Refunds are possible if:

    • Your device is incompatible
    • Your trip is canceled or you no longer need the eSIM
    • Network issues persist after troubleshooting
  • Refunds are issued to the original payment method within 3–5 business days.
