Dumb mobile phones still have SMS, so 2FA still works and since it is a telephone, talking to friends and family is also possible.
I suspect the reasons the OP gave up on the smart phone was to get away from all of those phone apps.
While SMS-based 2FA may be worse than the alternatives, it is clear that the previous commenter has decided that having a smartphone is much worse than the alternatives.
Unless their financial institution offers a non-smartphone 2FA option, such as a PIN-based card reader[0], having to use SMS-based 2FA is a reasonable price to pay.
For wire transfer there are still alternatives although becoming more and more difficult unfortunately. Other things one can still do without a smartphone, and the benefits outweigh the cons (for me at least).
