Good day, dear representatives of the company Blackview. There is a big problem with the new BV6000. It is not connecting to the network. Antenna empty. Another same model and it works great. There is a suspicion that the phone does not fit in frequency in our country, Russia. While doing the search for networks it sees the operators but can't connect. SIM cards work in both slots. We are even ready to pay the repair, really like this smartphone. Did a full reset.
Communication module MOLY.LR11.W1539.MD.MP.v10,2016/06/20 11:02
The build number BV6000_Blackview_V01_20161011
serial number VG45GENFDEQ8R8ZL.

Hi,
We have so many BV6000 users in Russia, and no such a complaint before, but you can still can check
the frequence that this model supports via our official website?
