Why did BHIM UPI registration fail?

BHIM UPI registration may fail due to several technical or account-related reasons. Common causes include:

• Mobile number not linked to the bank account.
• Insufficient SMS balance or lack of an active outgoing SMS pack.
• Weak internet connectivity or mobile network issues.
• Using a dual SIM phone where the registered number is not in the primary slot.
• Temporary bank server downtime or using an outdated version of the app.

Ensure your mobile number is linked to your bank and that your device has proper network permissions to complete the verification.
