I'm an Australian travelling in Asia on a budget. I've always travelled without getting local SIM cards so no phone. I rarely make purchases online.
About four months ago I bought a flight online with my ANZ Visa card from Taiwan to Japan with no problems. Last night I tried to use the card to buy a flight online with a different airline from Korea to Bangkok, but this time a popup window informed me the transaction has to use "Verified By Visa" which sent an SMS to my old Australian mobile phone number I haven't used since January. There were no options to "verify" any other way.
ANZ online banking does not have a way to remove my mobile phone number, just to change it. At the moment I don't have a friend's number I can change it to. In any case the popup had a message from ANZ telling me I had to make an international phone call to them to change the phone number associated with Verified By Visa. (Hence I do not know if the VBV phone number changes when I change my phone number in my online banking.)
I refuse to pay for an international phone call which will probably result in getting put on hold. And in any case I don't have a SIM card and am about to leave this country so won't get one.
While I'm waiting for ANZ to reply to my message sent via online banking, does anyone here know if it's even possible in 2019 to use Verified By Visa with ANZ in some way other than SMS to a mobile phone number?
(I recall being surprised and frustrated by Verified by Visa on other trips before in other ways but don't recall the details. Probably forgotten rarely used passwords or two factor authentication via Gmail blocked in China or something.)
