alot of people have reported that sprint htc one will not work on alot of networks since its cdma but it has gsm so if you wanna take a risk go for it i would reccomend a att or google play version to use outside usa
It will work... It has the GSM radio in it so it working on a GSM network isn't the question on hardware...
The only catch is you have to have Sprint unlock it for International Carriers. If they do this you're fine. If you want it unlocked for domestic carriers though (T-mobile / AT&T) they will NOT do it for this.
im aware of that but it has limitations....
Just FYI.
