Deactivate a mobile number linked to bank account
Answers
The truth is that you cannot permanently delink your mobile number from UPI services. You can uninstall a UPI app if you don’t like it, or delete the account from the app’s profile, but it never unlinks it.
What I mean is that if you were to lose your sim card, the person who found it, can trasact with UPI instantly, and withdraw all your money. They don’t even need to know your account number. But they do need to know your debit card number. So if you were to lose your phone, it would be best not to lose your wallet too!
You can’t remove your mobile number and account attached to the number from UPI, unless you visit your branch and change the registered mobile number. Some banks also allow you to change the mobile number from any bank ATM. The phone number is linked to your bank acccount, and as long as this is so, it continues to be linked to UPI service, whether you have installed the app or not.
Hope it helps
