Can I flash USA stock firmware (unroot) on Middle east region Z2 (D6502,not rooted) ?

hi folks
I have a Z2 d6502 model and its not rooted and the bootloader is still locked
Im on 5.1.1 stock firmware 23.4.A.1.232 middle east version
Can I flash a USA region 23.4.A.0.546 / R6C firmware via flashtools ?
I downloaded it via XperiFirm and here are the info it gave me about the firmware :
-------
Device: Xperia Z2 (D6502)
CDA: 1281-9706
Market: USA
Operator: Customized US
Network: GLOBAL-HSPA
Release: 23.4.A.0.546 / R6C
Size: 1.39 GB
-------
since Im in middle east, will there be any problems ?
It says operator is customized of the US, so Does that mean that I cant use my sim card and make calls once I flash this ?
