I don't know how it work actually, but when the seller tell me , it has a Vpn router and inside also has the Vpn service! . The things i do is just connect my vpn router with my wifi router and then i can use this just like Normal vpn.
I dont know what are you thinking about my post. But I alrady used it more than one year, and before vacation i went back to my hometown and i give it to my frd to borrow. After came back i buy a new one. So the one i borrowed to my frd still work!
If you want to complain me about i'm lying to buyer... lpls respect to others! Im not the one who produce this thing , i just bought , used (and i see it's work) and wanna sell it, if you wanna know how's it work go and ask the seller or search the information about another kind of this vpn.
Im not the kind of lying person, if you wanna know the information pls ask other that also use this thing.
