T-Mobile stock rom on 920i from Singapore

Hello,
I have bought a note 5, which came with a singtel app, so it came probably from Singapore (good, because no region lock). It lacks Samsung pay and T-Mobile WiFi calling, so I am wondering what are my options for installing a different rom that would include any of these features, ideally the stock from t-mobile. Before I root the phone, any suggestions or pointers?
Best,
Do

Huawei Honor U8860 - Stock Rom B930 Singapore Camera - Upload request

Hi everybody,

I'm looking everywhere about the stock rom B930 Singapore Camera for Huawei Honor (U8860). The exact denomination is "V100R001C388B930". This stock rom is no more downloadable from Huawei official site :/

If you own this rom, could you upload her somewhere ?

Thanks a lot !
