Go to the FAQ for Evolving Eevve below.
How can I tell if I’ve used a Nickname already without evolving?
You can tell if you used a Nickname already attempting to use it and changing your Eevee’s Nickname. If the desired evolution’s silhouette does not appear on the evolve button, then you’ve already used that Nickname before to guarantee that evolution.
For example, if you are trying to evolve an Eevee into a Leafeon using the Nickname trick, you would see Leafeon’s silhouette. Otherwise, you likely used it previously.
Is there anyway to guarantee Vaporeon, Jolteon, or Flareon?
The only way to guarantee Vaporeon, Jolteon, or Flareon is using the nickname trick. Each name will only work the first time it is used. Afterwards it is random which of the three you will recieve.
What time is considered day/night to evolve Espeon/Umbreon?
Day and night are based your local time. They can be determined by looking at the environment and sky in-game. If it’s day in-game, you can evolve in to an Espeon. If it’s night in-game, you can evolve in to an Umbreon. To verify which your Eevee will evolve into, you can look at the silhouette and evolution information on the evolve button.
How do I obtain a Mossy Lure Module/Glacial Lure Module?
Mossy Lure Modules and Glacial Lure Modules are occasionally given as Research rewards so you might already have one in your item bag. Otherwise, you can purchase them in the in-game shop.
I’m not near a PokeStop with the right lure, can I still use the nickname trick to evolve a Glaceon or Leafeon for the first time?
Yes, the nickname trick does not have any other requirements. You just need to nickname your Eevee. Make sure to check the silhouette on the evolve button that you have the evolution or haven’t used that Nickname already.
