I have a cell phone dedicated to my cryptos. Just asking if the cell phone lacks the SIM card is an extra way to protect me against hackers or wathever.
Thanks!

It is relatively safer than a phone with SIM card, but still it depends what kind of attacks you're expecting and trying to protect from. If an attacker has the capability to tamper with a device by allowing it to connect using a SIM, then I won't see why they couldn't exploit any wifi network used by the cell phone.
Offline storage such as a ledger USB is safer.

I would never have my main wallet in a device I can take outside and lose it. Also, always use a hardware wallet and pair it with your browser/app wallet.
If you really must have it on your phone, create a separate wallet and keep a smaller amount there.

I think a cell phone without a SIM card is a lot safer because then the hacker has to either hack the phone or hack the cellular network to steal the crypto. If there is a SIM card in it, all they have to do is social engineer the phone company to do a SIM swap, and anyone that works at the phone company could steal all of the crypto. As long as it's not set up so a text message is all you need to steal the crypto, even a cell phone with a SIM card is pretty secure.
Cell phones are pretty difficult to hack - especially if you don't use it for normal web browsing or email, and keep the security patches up to date.

It doesn't really matter. What matter more is what network you're connected with while doing transactions.
!!! NEVER DO ANYTHING ON YOUR BANK ACCOUNT/WALLET WHILE IN A PUBLIC WIFI !!!
A connection to a service provider is much more difficult to "hack". And as JohnS0N said, having your wallet on a mobile phone might not be the best idea.

Being on a public wifi would allow for man in the middle attacks, but don't all crypto connections use encryption that assumes that the network would be compromised?
If someone could steal crypto from a public wifi, they could just get a job at an internet backbone and steal everyone's crypto at once. Obviously they aren't doing that.
Pretty much all modern connections these days assume that the channel can be compromised and use key exchange countermeasures so the client can be 100% sure that it's talking directly to the server.
The cell phone vulnerability, as I understand it, is only an issue if crypto exchanges rely on the security of text messaging - which is a bad idea because text messages are only as secure as the phone company, and phone companies have next to no security against insider attacks.

Go there, grab a compatible ThinkPad (that recommended X230 + 16 GB RAM should be less than $200 used, avoid HDD ones or upgrade to SSD). Online banking goes into clearnet VMs, crypto stuff into Whonix VMs and you're good. I don't trust hardware wallets.
