If you purchase a mobile phone in installments through China Unicom Mall, you need a credit card to purchase it in installments. You can purchase a contract phone by installment payment, which is the same as an ordinary contract phone. China Unicom’s iPhone 6 does not have a customized logo, so you can buy it with confidence. If you purchase at a physical store of China Unicom's own business hall, you will also need to provide a credit card before you can pay in installments.
