How to use an idle phone to create a cold wallet.

First, prepare an idle phone, format it, and then download any wallet from a secure official website (I use MetaMask, but this is not a recommendation, use your own judgment). After downloading the wallet, create the mnemonic phrase while in an offline state. Once the mnemonic phrase is created, write it down manually.

Then enter the wallet interface, copy the newly created wallet address for receiving funds, whether it is TRC20 or ERC20 is fine. Then, on your commonly used phone, download the same wallet as the idle phone, or any wallet that has an address observation feature; just click on the observe address option on the wallet creation page.

Later, when you need to transfer funds to the cold wallet, just record the previous address. You can check the wallet account's balance using the observation address on your commonly used phone. When you need to send coins, simply turn on the hotspot on your commonly used phone to transfer to the idle phone. This way, you achieve the functionality of a regular wallet while also enjoying the security of a cold wallet.​​
