In Pokémon HeartGold and SoulSilver (HGSS), players have the unique opportunity to register Gym Leaders' phone numbers in their Pokégear. This feature allows you to call them for rematches, which adds depth and replayability to the game. However, getting their numbers isn’t automatic—you’ll need to meet specific requirements for each Leader.
To start, most Gym Leaders will only give you their number once you've defeated them in battle. After that, you'll usually need to find them at a particular location at a specific time or day. For example, Falkner, the Violet City Gym Leader, can be found at the Celadon Department Store on Sundays after you’ve beaten him. Talk to him there to register his number.
Each Gym Leader is tied to a usa cell phone number data specific day of the week and location. Here's a quick overview:
Falkner – Celadon Dept. Store, Sunday (Morning)
Bugsy – Viridian Forest, Thursday (Afternoon)
Whitney – Goldenrod Dept. Store, Saturday (Afternoon)
Morty – Bell Tower, Monday (Night)
Chuck – Cianwood City, Wednesday (Afternoon)
Jasmine – Olivine Lighthouse, Wednesday (Morning)
Pryce – Lake of Rage, Tuesday (Morning)
Clair – Dragon’s Den, Friday (Night)
After registering their number, you can call them during certain times (usually in the evening) to request a rematch. These rematches take place in Saffron City’s Fighting Dojo, offering stronger versions of their teams.
Collecting all the Gym Leader numbers is a fun side quest that enhances your post-game experience and offers a great way to train your team. Make sure to bring a Pokémon with the Pokégear and check your timing so you don't miss out!
