I always hear the “I need my phone for bank stuff” but can’t you just leave your phone at home and then schedule going to the bank if it’s that necessary to a part of your day? I can’t imagine you need to be interacting with the bank 24/7/365.
"Going to the bank"? Banks around here began to close physical branches well over a decade ago now, and visiting one of the remaining branches often requires a multi-hour wait in the queue, if not an appointment made many days in advance.
The “I need my phone for banking” excuse is a vague reason to keep using it. They don’t need their phone for banking, they want their phone and banking is a convenient reason to placate that want.
It's not your country. It's the banks' country if they own it to the extent that they own your identity.
