I have 4 accounts
SBI - for any kind of Govt. and investment related activities (like Standing Instructions) as Govt. banks have the cheapest start and cancel charges
ICICI - Salary account
HDFC - Primary account
BoB - Secondary account
I was planning to open one more digital account on a differet number, (but same PAN Card), so that in case my Primary Mobile number linked to the banks do not work or gets stolen or hacked or soemthing, I will have a back up account.
But, I am also scared that it may be a lot of accounts (5 in total).
Need some suggestions.
