Mars eSIM is classified as an “international telecommunications service” (e.g., international data cards, roaming cards). According to the Value-Added and Non-Value-Added Business Tax Act of the Republic of China (Taiwan), such cross-border telecommunication services are subject to zero-rated VAT and are not required to issue a uniform invoice. Therefore, we do not provide additional electronic or paper invoices.

Zero-rated VAT refers to specific types of transactions that are subject to a 0% VAT rate. According to tax regulations, services that qualify as cross-border telecommunications — such as eSIM international data plans — are used outside of Taiwan, and therefore meet the criteria for zero-rated VAT.

⚠️ Since zero-rated transactions are not required to issue invoices, electronic invoices are also not applicable.

Yes! A “Purchase Receipt” (not a uniform invoice) can be provided for each order.
The receipt includes: product names, amounts, payment method, and other related details.

• The receipt reflects the total amount for the entire order; itemized or split receipts are not available.
• If any coupon or discount code was applied, the receipt will show the discounted amount.
• The receipt can be used for internal reimbursement or personal record purposes.
