Not only that, but also when you are abroad.
While I have the Wise app on my phone, I always prefer to use the web version, as I also do with other online platforms, because of bigger screen.
My previous verification method was set as text message to my Thai phone number.
When I went to Europe recently, that would mean I had to keep Thai SIM in my phone with roaming enabled. This may not be convenient for some, unless your phone is dual SIM enabled.
This way I would receive the verification code in the WhatsApp app on my phone with a foreign SIM inserted, or on the tablet which I carried with me, and which I was using to connect to Wise
