Common questions

Find an answer and get back on track.

How do I purchase and access a product?

Choose a product and plan, add it to your cart, then sign in and proceed to checkout. Select an available payment method and complete the order. After payment, visit My orders to check its status and access your purchase. Complete phone verification if prompted. The order page shows the delivery status.

I’ve paid. Why can’t I access my purchase yet?

Check the payment and delivery status in My orders, and complete any verification requested on the page. If payment is awaiting confirmation or delivery is pending, do not pay again. Contact support on Discord or LINE with your order number for help.

When is phone verification required?

Some payment and order-viewing flows require phone verification. Follow the instructions on the page. You can view your linked phone in Account profile, but cannot change it yourself. Contact support if you need to replace it.

How do I view my balance or top up?

After signing in, open My wallet to view your balance and top-up history, or start a top-up. Select a payment method and check the service fee and total shown on the page. Complete phone verification first if requested.

What if a product is under maintenance or unavailable?

Temporarily unavailable products may still appear on the website or in your cart, but are excluded from the total of items available for checkout. Choose an available product or check back later. For issues with a paid order, contact support with the order number.

How do I change language? Does the currency change?

Use the language selector at the top of the page. The website remembers your choice. Changing language does not change the currency: all prices are shown in New Taiwan dollars (TWD).
