Firmware from another country.

[Fabiano4141]

Hey there fellows, I'm new here, thanks for having me! I've got a question and would appreciate if someone could help me! I've bought a Note 8 in the UK with an EE contract and tried to use Samsung Pay but the app doesn't work. After that, I've checked that the phone is from Germany (SM-N950FZKADBT) so I would like to know you if I can flash an UK firmware via Odin without having any problems and keep on using my EE plan. Hope you understand my English! Many thanks!
