In the A series, only the A56 and A36 are supported for the Nol option, not the A55.Tap your NOL Card straight from your phone | Samsung Gulf https://share.google/edrEgIdioH9t1Bcji
I'm in UAE and the message is also displayed that I can add nol card to Samsung Wallet. But in the 'Transit Cards', the option is not available there. I have the required latest Wallet version, and Android 16, Galaxy A55.
