So with my secure element SIM card,I should already be able to make NFC payments with tap to pay?SIM card with enabling.
In WP 8.1, they've pulled out any functionality for NFC payments from the Wallet app itself. This way, carriers can make their own app that controls this sort of stuff. My guess is that's a concession to the group formerly known as Isis, which involves T-Mobile, AT&T, and Verizon for the US markets. Still, nothing has panned out yet.
