The only way to get the Sinnoh starters in Pokemon HG/SS is to trade it from games Diamond, Pearl, and Platinum.

Kanto/Hoenn-migration. Also for Johto but you must migrate from Emerald, after beating the league in Emerald, you go to the Safari Zone and there'll be a new area. In the new area you can find Johto Pokemon including the starters (the starters are EXTREMELY rare to find though.)
