TL;DR

VietQR payments on an iPhone may be unreliable, while Android payments are reported to work more consistently. In Nha Trang, keep banking apps ready, carry more than one card, and have some cash available from ATMs as a backup.

What the community said

For day-to-day spending, do not rely solely on QR payments: keep banking apps on your phone, carry two cards, and have a few cash notes with you.

Two cards and cash

Even when VietQR transfers generally work, occasional payment failures can happen. One reported example was a successful VietQR payment of 28,000 for a used iPhone.

If an ATM stops showing your balance after changing settings or a card, it may be a temporary glitch. Do not leave cash withdrawals until the last minute, and keep an alternative card.

ATM

QR payments may fail on an iPhone even when the same payments work on Android. iPhone users should especially keep cash or a physical card as a backup.

When mobile payment is unavailable, use ATMs for cash withdrawals and check the exchange rate shown by the bank or ATM before confirming the transaction.
