Use Zeus or Phoenix wallet for self custody. They're free to use.

You will still need some bitcoin to setup a Zeus, or Phoenix, or any other self custody lightning wallet. They don't charge subscription fees. You just pay the normal on-chain fees to miners to open channels.

Use a free custodial wallet like Wallet of Satochi until you have some Bitcoin.

For ten or twenty bucks worth, or just starting out, just use a free custodial wallet.
