All Z1 compact spare parts are the same in all regions.
The difference is the carrier you choice.
Ok, but that's for the hardware.
I come from a HTC one and this phone had different versions, not all of them had the same 4G bands and so on.
The HTC also has versions specific for Sprint and verizon.
Depending on the CID you were able to install some rom versions and other ones not.
I bought my xperia z1c in the Netherlands but if I look at the documentation included it is not from The Netherlands but from one of the countries in Eastern Europe, I still don't know yet which one, I think I have to grab some words of the doc and put them in the translate.google to know which country.
I just want to make sure I will not encounter any problems if I would install a custom rom.
Up to now the phone is not yet in use because I'm waiting for the screenprotector, coming from China, still not arrived (it is a full body protector) and the ones you can order in the USA are too expensive due to the transport costs.
