The Z Force is and always will be exclusive to Verizon in the US. It won't be on other carriers or internationally (at least as the "Z Force"). The regular Moto Z is available unlocked in the UK right now, so you might be able to find one and get it to work in Russia, but it's probably not there yet. The Z Play will be avaliable internationally in a couple months, but is only available in the US from Verizon right now.
