Changing a registered mobile number without an OTP (One Time Password) can be challenging as most banks and service providers use OTPs to authenticate the process. If you cannot receive an OTP on your registered number, you might need to personally visit the bank or service provider’s branch. Bring your identification documents for verification. The staff will assist you in updating your contact details after verifying your identity. It’s a safeguard to prevent unauthorised changes and protect your account.
