UOB is still in the dark about what is expected in today’s world of internet banking and mobile banking. The website is worse than most from the late 90s and their app is completely non-functional (hangs on loading screen). If I wasn’t forced to use this Bank for financing, I would stay away based on how little they understand what is required as a baseline for a respectable international bank.
If you are looking for seemless interaction with a Bank, then keep looking. UOB has been worthless for the past 3 years, and even with recent updates to both app and website, they are still far behind their competition, even with the bar set low by other Asian and local banks.
