Players will be able to visit their friend's towns and invite them to their own towns in the new upcoming Animal Crossing mobile game like other mobile games have PVP (Player versus Player). Let's look back on how to visit other towns in Animal Crossing: New Leaf, the past Animal Crossing game.
Train Station
In Animal Crossing mobile game, you will use your account ID to contact to your friends. Then you can invite your friends to your town or get invited from them. When you visit other towns, use Train Station. When you host your friends, go to the place to pick them up.
Why do we visit other towns?
Here are things assumed to be that you will do by visiting other towns or invite them to your town:
Catching rare fishes
Probability of catching rare fishes increases while you are visiting other towns or having guests in your town.
Selling your town's native fruit

Getting other town's native fruit
You will be able to carry other town's native fruit back to your town. Re-Tail in your town buys those rare fruit at a high price.
