OCB (Orient Commercial Bank; in Vietnamese, Ngan hang Phuong Dong) has one notice for residents who hold an account there. Starting August 19, 2026, SMS notifications for balance changes on some deposit products will stop, switching to free push notifications on the "OCB OMNI" mobile app. Anyone in the habit of checking salary deposits or transfer activity by text message will stop receiving those notifications altogether if they haven't installed the app. For Japanese residents in Vietnam who use mobile payments and banking apps, missing this change could throw off how you track your take-home money.
SMS notifications stopped for five term-deposit and savings products
According to OCB, the SMS notification suspension applies only to personal deposit products. Specifically, it covers five products: electronic term deposits (Tiet kiem/Tien gui dien tu), Omni Flex, electronic recurring deposits, the optimal-yield term deposit under Max Savings, and the flexible-yield certificate under Flexi Savings. For transactions on these products — issuing funds, partial withdrawal of principal, full closure, or a change of account name — notifications that used to go out by SMS are now consolidated into OCB OMNI app notifications. Not every everyday transaction on a regular savings account is affected right away, but for accounts holding a term deposit or recurring savings plan, the app becomes the only channel for notifications.
SMS costs money, the app is free — a shift in who bears the cost
SMS balance notifications from Vietnamese banks have long been offered as a paid service with a monthly fee. The more transactions you have, the higher the monthly charge, since a cost is incurred for every notification sent. From the bank's side, this is also an area where the SMS fees paid to telecom carriers add up. Moving to app push notifications removes this entire cost structure. OCB describes the switch as "optimizing the customer experience and offering a convenient, free way to receive notifications" — for users, the notification fee disappears, while for the bank, it cuts sending costs. This SMS-to-app shift isn't unique to one bank; it's more accurate to see it as part of a rationalization move that Vietnamese banks are making in step with each other.
What makes this confusing is that this August, several Vietnamese banks rolled out account-related rule changes all around the same time. Some banks introduced new management fees for dormant accounts, while others are moving to suspend transfer functions for accounts without registered biometric data. Those changes are about fees or identity verification, and are a different kind of change from what OCB is doing here, which only changes "how the notification arrives." OCB's announcement isn't a new fee or an account freeze — it's limited to one point: shifting balance-change notifications from SMS to the app. It's best not to skim the headlines and jump to the conclusion that "fees went up again."
Residents without the app, or with notifications turned off, will be the ones left out
The people who will actually run into trouble because of this change are residents who hold an account but haven't installed OCB OMNI, or who have it installed but have turned off notifications on their device. Typical cases include people who just arrived in Vietnam and rely only on SMS, people who haven't reinstalled the app after switching phones, and people still using a Japanese phone number alongside a Vietnamese SIM. It's possible for a term deposit to mature, or for a transfer to arrive, with nothing showing up on screen. Banking app changes keep coming — the PIN rules for transfers changedin the July 30 app updateandthe biometric registration that can suspend an accountand, in the same vein, keeping the app updated and notifications allowed is increasingly becoming a baseline requirement. Assuming "no notification means no transaction" is the most dangerous mistake to make.
One thing worth being especially careful about: unlike SMS, which arrives regardless of device or settings as long as there's signal, app push notifications depend on the device's own settings. On both iPhone and Android, notifications can fail to show up because of power-saving mode, background refresh restrictions, or notifications switched off for that app. If you're using a Japanese phone as-is with a Vietnamese SIM inserted just for data, it's worth checking whether that number can even receive SMS in the first place. Term deposits don't move often, but it's exactly the high-value transactions — maturity or closure — where a missed notification ends up mattering most later. Anyone tracking salary or client payments through their account balance should treat the app's notification history as their only real-time record.
Account checks to make today
- Install OCB OMNI and keep it updated to the latest version. Turning on automatic updates in the App Store/Google Play also cuts the risk of missing something.
- Turn on push notifications for OCB OMNI in your phone's settings. Also check whether airplane mode or power-saving settings are suppressing notifications.
- If you have a term deposit or recurring savings plan (Max Savings, Flexi Savings, etc.), switch your assumption so that maturity or closure payments are expected to arrive as app notifications.
- If you've changed your phone number, check that the number registered on OCB OMNI matches the one you're currently using.
- For questions, call the hotline at 1900 1846 (priority customers: 1800 6678).
Not receiving SMS anymore isn't a loss in itself — it's actually a positive change that removes the notification fee. But that depends on OCB OMNI working correctly on your phone. If you hold an OCB account with a term deposit, it's worth opening the app today and running a test transfer to confirm the notification actually comes through.
