Can I use Samsung Pay with Wi-Fi?

pu1. At first, you have to connect to data such as 3g, 4g, and LTE, and after you check it once, you can also connect it to Wi-Fi.
But if it's a zero plan, there's no way to connect

OK

pu2. I don't use Samsung Pay because I don't use data either

OK

pu3. Samsung Pay and Hyundai Card also told me to connect to the data
They said there's no way to ask the customer service
Shinhan Card works well on Wi-Fi, so I only use Shinhan Card for the app card
