Why +65 1800-222-2121 fails from a foreign phone
On a toll-free number, UOB (United Overseas Bank) pays for the call instead of you. Carriers generally only route these calls from networks inside the area the number covers, here Singapore. A call from a foreign SIM, or from a home SIM roaming on a foreign network, has nobody to bill it to, so the network rejects it. You usually hear "your call cannot be completed as dialled", a fast busy tone or silence.
That's why UOB (United Overseas Bank) lists +65 6222-2121 for callers outside Singapore. Dial that one with VoixCall.

Record the call and keep the reference number
A call to UOB (United Overseas Bank) usually ends with a case or reference number and a promise about what happens next. After a long hold, in a second language, it's easy to miss a digit.
Switch on Record on the VoixCall dialer before you call ($0.003/min). If you've also turned on "Record and transcribe my calls" in Settings in the web app, about a minute after you hang up Call History shows a short summary, the reference numbers that were said (each with a Copy button), what each side agreed to do next, and the full transcript, for $0.02/min.
Recording is off by default. UOB (United Overseas Bank) hears a short recording notice when the call connects, and only you can see your recordings and transcripts.
