I'm definitely at a loss here @waquzy and all I can think of is it being because of the non UK version of the phone, although as you say it should work because we get Samsung pay here. Sorry I couldn't be of more help buddy.
No worries mate, thank you for your help. I will pop into one of the Samsung stores in the near future....
That would probably be your best idea mate incase we're missing something, let me know how you get on.
Exactly the same problem with the S6. Perfectly legit phone on Vodafone in the UK, not rooted (I wouldn’t know how), stock model, will not run Google Pay, will not run Samsung pay. When I try google pay I get an error message about the device being rooted, unlocked boot loader or custom ROM. No idea what any of those are but I haven’t messed around with it, it’s stock. Samsung Pay doesn’t work either. I tried it, it failed, and now the App Store isn’t even finding it for me. It’s so annoying. I used tap and go payment perfectly on my J3 and it ran perfectly. What is the problem, and how can I get my S6 to work with a phone pay system? It’s so annoying and there seems to be no help available.
Also having the same issue. US based, but have an international phone(my software model pulls up Turkey, but Samsung Pay has been advertising things relevant to South Africa). It won't let me add Discover into the wallet because of this :(
