How quickly can I use the eSIM after purchase?

You'll receive a QR code within minutes of purchase. Simply scan it to install the eSIM on your device—no physical delivery time. Activation is instant; data begins when you scan and install.

Will this eSIM work on my iPhone/Android phone?

Yes, if your device supports eSIM and isn't carrier-locked. Most devices from China and Hong Kong don't support eSIM. Check your device model's specifications online or contact your carrier before purchasing.

Can I make phone calls or send SMS with this plan?

No, this is a data-only plan. Voice calls and SMS aren't supported. However, you can use data-based apps like WhatsApp, Telegram, Viber, and FaceTime for communication.

What happens if I don't use all 20GB in 30 days?

Unused data doesn't roll over and isn't refundable. Plan carefully based on your estimated usage; 500MB daily covers navigation, emails, and light social media but not heavy video streaming.

Can I share the data with others using mobile hotspot?

Yes, mobile hotspot is supported. You can create a personal hotspot and share your data connection with travel companions' devices, though this will consume your daily allowance faster.

What's your refund policy if the eSIM doesn't work?

No refunds are issued for compatibility issues or plan changes. Verify device compatibility before purchasing and activate only on confirmed travel dates. Contact supplier support via email if you experience activation problems.
