Plutonium

I have a big problem and it is that I don't have a router or Wi-Fi connection and I use mobile data to play plutonium but the nat is strict and I have searched for videos and everything and I can't play with friends. Does anyone have a solution? and Radmin vpn and hamachi have not worked for me either

I can't do the final step of the mob of the dead easter egg when I get on the plane in afterlife mode it won't let me and no interaction button appears and I'm playing in original mode
