To do Paytm UPI, you must link your bank account to the Paytm app using your registered mobile number. Follow these steps:
- Download and log in to the Paytm app with your bank-registered mobile number.
- Go to UPI and Payment Settings and tap Add Bank Account.
- Select your bank; the app will verify your number via SMS and fetch account details.
- Set a secure UPI PIN using your debit card or Aadhaar details.
Once set up, you can instantly send or receive money using a UPI ID, mobile number, or by scanning any UPI QR code.
