Insufficient Network Fee

Hello. I recently join the coin world and I wanted to take some ceek tokens. I sent money to binance and get some ETH. After that I sent these ETH to trust wallet but at the end I want to send them to pancakeswap. Hovewer, I couldn’t send because there is a network fee which is only paid with BNB smart chain. I don’t have any bnb and I don’t know how can I solve this problem ? Can anyone help me with that problem ?

Have a nice day

BNB Smart Chain Account : 0x5fD1501cE4A221F5C2Ab8cC8c19aE6Aa93cff15f

The network fee is only 0.3 cent but I don’t know how to buy that with my ETH
