Choose between iPhone and Samsung Galaxy by the operating system you prefer, then compare the display, camera, battery and storage. A 128 GB model may suit basic use, while frequent video recording or large app libraries may call for more space. Check eSIM, 5G and the exact model specifications rather than assuming features from a series name.
For a used phone, review the condition, battery, included accessories and warranty stated on its product page. Compare models with the same storage and condition; a lower price does not necessarily mean the same device condition or after-sales coverage.
For installment payments, check the OnePay option on the product or checkout page. When enabled, it is available for eligible orders from VND 3,000,000 and depends on the credit card, bank and term. Review the interest, fees and total payable amount at the payment gateway before confirming.
