Sadly I can't I use my mobile hotspot almost all the time and it's a bit of hit and miss, might work today and won't work tomorrow it's really annoying I can search other players but can't join any game or room I could also create a lobby but others can't join .Then suddenly it would work the next day. Does anyone know how to port forward on android or any other solution I don't have access to a router am on the move most of the time that's why I love my 3ds because it's portable but I can't seem to enjoy multiplayer on it
