First of all if you have samsung pay installed the one comes pre installed..you need to clear data then uninstall it . Then restart ur phone then go to samsung store and install the new version called samsung wallet, do you setup with ur bank info .
Unfortunately, nothing has changed. The service appears unsupported on your phone. I sent a message to support. I will wait for a response from them. Thank you for your help.
