How quickly can I use the eSIM after purchase?

You'll receive a QR code within minutes. Simply scan it on an eSIM-compatible device to activate instantly—no waiting for physical delivery.

Will this work on my phone?

Only on eSIM-compatible, non-carrier-locked devices. Most phones from major global brands (Apple iPhone XS+, Samsung Galaxy S20+, Google Pixel 3+) support it, but devices sold in China and Hong Kong typically don't. Check your device specs online or contact your carrier before purchasing.

Can I use this for calls and text messages?

No—this is data-only. Use internet-based apps like WhatsApp, Viber, Skype, or iMessage for calls and messaging instead.

What happens if I don't use all 50GB in 30 days?

Unused data expires after 30 days. The plan is one-time prepaid with no rollover; plan your data needs accordingly or activate closer to your travel dates.

Can I share this connection with others?

Yes—mobile hotspot is supported, so you can tether the eSIM to other devices (another phone, tablet, laptop) for shared connectivity.

Is there a refund if I don't use it or my plans change?

No refunds are issued for any reason, including compatibility issues or itinerary changes. Verify your eSIM compatibility and travel dates before purchase.
