When is the earliest an NPC can call you for a rematch in HG/SS?

Question

In heart gold, lass dana can call you for a rematch and if you do this you can get a thunderstone but when is the earliest this can happen?

Answer 1

The question was not worded very clearly, but I think this is what it's asking for.

In HeartGold and SoulSilver, Trainers will only begin calling the player for rematches once the player has collected seven Badges and beaten Team Rocket at the Radio Tower in Goldenrod City. In addition, once the Radio Tower has been saved, the player can call registered Trainers to arrange rematches with them without having to wait for the respective Trainers to call the player.

Basically.

Source contradicts the answer. It looks like in HGSS Joey will only call for a rematch three times, and it looks like it’s pretty late in the game. It says on the second battle, he’ll have a level 34 Raticate. I think this would’ve been noted if he could have a level 34 before the first gym.

Answer 3

I don't know when the earliest she can phone you is, but Seribii says you can call her on Thursday nights, provided you are not on Route 38, for a rematch. You can do this as many times as you like on the same night, but I am not sure if you have to pass a certain point before she gives you the stone for beating her. You might have to beat her 4th team. I will have to test this.
