I understand you require a developer to fix the “Invalid SMS Timing on DLT” error and ensure 24x7 OTP delivery through MSG91 and Jio DLT for your mobile app. You need verification of your MSG91 account setup, Jio DLT template mapping, and proper API integration to handle transactional routes effectively. With over 15 years in full stack development and API integration, I have completed more than 200 projects involving PHP, Node.js, and REST APIs, including multiple SMS gateway and DLT compliance tasks. My experience with backend troubleshooting and SMS API setups aligns well with your needs. I will start by auditing your MSG91 configuration and Jio DLT templates to identify timing and routing issues. Then, I’ll adjust the OTP API integration for seamless compliance and test OTP delivery across Jio, Airtel, and VI networks to confirm consistent performance. This can be completed within 2-3 days given the focused scope. Feel free to share more details so we can get the OTP system running smoothly without interruptions.
