Pokémon Global Link service ending late February 2020
With nine years under its belt, the Pokémon Global Link service used by millions of 3DS owners worldwide will be retiring. As of February 24th, 2020 you will no longer be able to use any gameplay features that require a connection to the PGL on your Pokémon Ultra Sun, Pokémon Ultra Moon, Pokémon Sun, or Pokémon Moon games. Players will still be able to use other online functionality of the titles apart from the PGL.
Pokémon Sword and Pokémon Shield will have similar features as to what was on offer through PGL, all of which will be available through the Nintendo Switch.
