Linking Pokémon GO to Nintendo Account is necessary if you want to take full advantage of what Pokémon Home has to offer. Linking your accounts will allow you to trade and move Pokémon between Pokémon Bank, GO, and Switch games.
Fortunately, setting up Home is easy. First, download the Pokemon Home app on your phone. Then you can sign in with your Nintendo Account. Next, you will need to go to Pokémon GO and go to Tuning Equipment. Find the Pokémon Home option and you’ll sign back in with your Nintendo Account.
That’s all you need to do to link your account. From there, you’ll be able to store up to 30 Pokémon in Pokémon Home and access them from Pokémon Sword and Shield, Let’s GO, Pokémon GO, and even Pokémon Bank.
In Pokémon GO, you can only transfer a few Pokémon at a time as it will deplete the GO Transporter’s energy. It will fill up over time. The rarer or stronger a Pokemon is, the more energy it will consume.
There are premium plans that give you more storage, billed monthly. It’s $3 for one month, $5 for three months, and $16 for the year. Only Premium Account holders can move Pokémon from the bank, use the Judge function, or create Trading Rooms.
