Why did my BHIM UPI registration fail?

BHIM UPI registration usually fails due to verification issues between your mobile number, device, and bank account. Common reasons include insufficient SMS balance to send the mandatory verification message, weak network connectivity, or the registered mobile number not being in the primary SIM slot. Additionally, registration can fail if your mobile number is not updated in bank records, the bank’s servers are down, or the app lacks necessary permissions. Ensure you have an active SMS plan and stable internet before retrying.
