You must have BNB network fees.

Guys, how do I buy from the Web 3 wallet? I don't know how to transfer it to it and I can't buy or return the money or make an exchange. It says for two days that there is an error in transferring the currency. The BNB balance is not sufficient to pay the fees, even though it was transferred to 27$ . Help me, may God heal you. I need a solution.
