iPhone for Cold Wallet

After I disconnect the internet, should I turn on airplane mode? should I turn off bluetooth ? I still want to use the phone for other purposes. Such as Cold storage of photos & other important references beside using it just a Cold Wallet.

Thank you,

You can ensure that the phone won’t connect to the internet, and the wallet mnemonic on the phone won’t be viewed by others. There are no restrictions on other uses of the phone.

Thank you

no internet is a key
