You can't.
To see a Phione, you need to breed a Manaphy with a Ditto, or you can use Astion Replay.
Manaphy is obtainable as an egg when you have beaten Pokemon Ranger, and can be traded to D/P/Pt.
we all know that, some of us don't have Pokemon ranger! and in platinum you cant get ditto cause it ain't on the sinnoh dex!
You must have Pokemon Ranger - Shadows of Almia. u get a phione egg and transfer that on heart gold. Ta-da you have a phione ( sorry if this is wrong.. for more info you can try serebii.net. )
You cannot catch Phione in HeartGold or SoulSilver. Phione is a legendary Pokemon, and can only be caught through a special event. This means that it is not available through normal game play.
In PoKéMoN HeartGold, you can find a Phanpy on Route 45 and Mt. Silver (towards the end of the game). It is not obtainable in PoKéMoN SoulSilver.
Unfortunately, you can only get Phione by breeding Manaphy and a Ditto. You'd have to have a Manaphy from DPPt events or Pokemon Ranger and trade it over to HeartGold to get one.
You can't find it you have to get a manaphy and a ditto and make them have an egg. when you hatch the egg you will have a phione.
You don't need Phione you need Rotom, at night go to the Eterna mansion, you know what to do, we all do.
you can not get phanpy in heart and silver. your best opinions is to trade it.

You obtain Phione by breeding Manaphy and Ditto in the Daycare. The Daycare Man will step closer, face towards you, or call you on the Pokegear (Pokemon HeartGold and SoulSilver) to let you know that the Phione Egg is ready to be picked up.
Phione isn't in Pokemon Ranger.
Phione is a Water type pokemon.
No, Phione is not the same as the Pokemon Manaphy.
No, but if you put Manaphy and Ditto in the Day Care together they'll eventually lay a Phione Egg.
