06. *Failover scenario in case GMiD™Box is not accessible? i.e are we going to use SMS OTP? and is using SMS OTP, who will provide the solution, and who will pay for the SMS OTP?

Usually all service providers already have SMS OTP and A2P sms providers integrated, which they can use as a fallback. So we always provide a COVERAGE API to app developers to check whether IPification is available or not. If it is not available, then just keep using whatever they have as the option (SMS OTP, email password etc.)
