I have to say, that game makes fun :)
But sometimes its little bit buggy.
I'm using "Vpn Download: Top, Quick und Unblock Sites" from Play store.
It works very well, enough to play this game.
Sometimes you have no connection to Vietnam servers, but that's not horrible.
Know I give you my secret selutio to ply this game without using during vpn :)
First you have to start any vpn app and you have to be connected to a Vietnam server.
Second, start the game and login with you Charaktere. If you are in the game, start step 3.
Third, disconnect from the Vietnam server and play with you mobile network oder wifi.
Very important is, don't completely close the game, only minimize!
Have fun to try this way, I hope I could help you :)
Sorry for my English.
I will try to answer your questions.
