Before using any wallet just keep mean mind that you are a beginner or an expert.Before creating any wallet just check whether it is device friendly or not. So I always prefer to use hardware wallets to store eth. Also nowadays trust wallet is very popular which supports more no.of erc20 tokens and beginners can use it easily as its interface is very simple.
I think if used on the phone, you should use Trust Wallet because this is the wallet that is recommended to use the most and has absolute security when used. In addition, this wallet has a great support from Binance so you can feel secure when keeping money here. Of course there are many wallets that suit your needs but it is best to research carefully.
