Anbox is ready to rock!
At first I had no reception on mobile. Wifi was working.
I shut down the phone, removed battery, switched SIM1 -> SIM2.
After that i have no longer wifi, but guess what, cellular data is working now making calls, no problem.
EDIT. My mistake. SIM2 works for calling, no cellular data, wifi works but doesn't show networks anymore. So i don't see i have wifi connection, but i'm connected.
And seems like i can't use the SD card.
EDIT2: After another reboot wifi's are showing up again, but have the indication that i am not connected to cellular network, but can make calls.
