I want to buy a cheap phone with a SIM card which I will only use for receiving text codes for Two Factor Authentication. I can't use my own phone as I have another account linked to it.
Is there a mobile phone company that offer SIM cards where you don't have to top it up and will still be able to keep the number without it expiring?
I know you can use an authenticator app but if the phone breaks or it's stolen, then it's almost impossible to recover.
(Sorry, if this is a silly question, I thought I'd ask for some advice.)
