There’s only one correct way to use Pokémon Go’s Eevee name trick
There are a lot of species to get in Pokémon Go, but players often have a soft spot for Eeveelutions. You might have to be patient to get them all, however, especially since it’s recommended to wait for a long time before using the Pokémon’s name trick.
Many players recommend waiting until Level 41 to use the trick because one of the missions to reach Level 42 is to evolve Eevee into each of its unique evolutions.
