Common YONO App Problems and Fixes

1. YONO App Keeps Crashing or Won't Open

Possible causes: Outdated app, low storage, OS incompatibility.

Fix:

1. Close the app completely and reopen it
2. Check if your phone has at least 500 MB free storage
3. Update the YONO app from Google Play Store or Apple App Store
4. Clear app cache: Go to Settings → Apps → YONO SBI → Clear Cache
5. If the problem persists, uninstall and reinstall the app
6. Ensure your phone OS is updated (Android 8+ or iOS 13+ recommended)

Tip: Do not install YONO from third-party APK sites. Always use official app stores.

2. YONO Login Failed — Wrong Password or Username

Possible causes: Incorrect credentials, account locked, special characters issue.

Fix:

1. Ensure you are entering the correct Internet Banking username (not account number)
2. Check that Caps Lock is off and password is entered correctly
3. If you've forgotten your password, tap Forgot Password on the login screen
4. To reset via the app:
   • Open YONO → Tap Forgot Login Password
   • Enter your username and registered mobile number
   • Verify with OTP → Set a new password
5. If your profile is locked after 3 wrong attempts, wait 24 hours or visit your home branch with ID proof

3. OTP Not Coming on YONO

Possible causes: Network issue, DND activated, SIM not in slot 1, SBI server load.

Fix:

1. Ensure your registered mobile number is active and has network signal
2. Check if DND (Do Not Disturb) is blocking transactional SMS — call your telecom provider to whitelist SBI
3. Keep your SBI-registered SIM in Slot 1 of your phone
4. Wait 2-3 minutes — OTPs can be delayed during peak hours (1st of month, salary days)
5. Tap Resend OTP if available
6. If OTP still doesn't arrive, try after 30 minutes or use SBI's Internet Banking portal instead

4. YONO Server Down or "Service Temporarily Unavailable"

Possible causes: Scheduled maintenance, high traffic, backend issues.

Fix:

1. SBI performs maintenance usually between 11:30 PM to 12:30 AM IST — avoid this window
2. On salary days (1st, 5th, 7th of the month), servers face heavy load — try during off-peak hours
3. Check SBI's official Twitter/X handle for maintenance announcements
4. Switch between Wi-Fi and mobile data to rule out network issues
5. If you see a persistent error, try again after 1-2 hours

5. Biometric Login (Fingerprint/Face) Not Working

Possible causes: Biometric not registered, phone sensor issue, app update needed.

Fix:

1. Go to YONO Settings → Login Preferences → Enable Biometric Login
2. Ensure your phone's fingerprint/face unlock is set up in phone settings first
3. Clean your fingerprint sensor and try again
4. If biometric fails repeatedly, log in with password and re-register biometric
5. After an app update, biometric may reset — set it up again from Settings

6. "Update Required" or App Version Not Supported

Fix:

1. Open Google Play Store or Apple App Store
2. Search for "YONO SBI" and tap Update
3. If update is not available, your phone model or OS may no longer be supported
4. Minimum requirements: Android 8.0+ / iOS 13.0+
5. If your phone is too old, use SBI Online Banking via a mobile browser as an alternative

7. Transaction Failed on YONO

Possible causes: Insufficient balance, daily limit exceeded, beneficiary not activated, server timeout.

Fix:

1. Check your account balance — ensure sufficient funds including minimum balance
2. Verify daily transfer limits:
   • NEFT/RTGS: Up to ₹10 lakh (default, can be increased at branch)
   • UPI via YONO: Up to ₹1 lakh per transaction
   • IMPS: Up to ₹5 lakh
3. New beneficiaries have a cooling period of 4-24 hours before first transfer
4. If the transaction failed but money was debited, it usually reverses within 3-5 working days
5. For stuck transactions, raise a complaint in YONO under Service Requests → Transaction Complaint

How to Reset YONO Login Password

1. Open the YONO app → Tap Forgot Password
2. Enter your Internet Banking username
3. Verify with registered mobile OTP
4. Create a new password (must include uppercase, lowercase, number, special character)
5. Log in with the new password

Alternatively, reset via SBI Internet Banking → Forgot Login Password.

How to Re-register on YONO

If you cannot fix the issue, re-registering often resolves persistent problems:

1. Uninstall YONO from your phone
2. Reinstall from official app store
3. Tap New User? Register Here
4. Enter your account number and registered mobile number

Important Tips

1. Always update the YONO app to the latest version for security and bug fixes
2. Never share your OTP, MPIN, or login credentials with anyone — SBI will never ask for these
3. Use strong passwords with a mix of letters, numbers, and special characters
4. Avoid public Wi-Fi for banking transactions
5. If money is debited but transaction shows failed, do not retry — wait for auto-reversal
