ONT Withdraw Problem. Help

Hello, I am trying to withdraw ONT from my wallet. I have 58 ONT and it says insufficient ONT to cover network transactions. How do I exchange ONT to ONG for withdraw fee? Both of them have same wallet address. Can anyone help me? Please. My app’s version is 1.28.2.

You can’t change ONT to ONG in the wallet, it is not supported. You need to get ONG as gas to be able to transfer your ONT.
To get ONG, you can buy via the third-party crypto provider that is integrated into the app (guide: https://community.trustwallet.com/t/how-to-buy-crypto-with-trust-wallet/507/2) or by withdrawing from an exchange (example: https://www.binance.com/en). If you have a friend who has spare ONG, you may want to contact them as well.
